Why Is Arabica Coffee Expensive?
When they buy coffee at the market or order a cup of Java with their meal, some folks are only interested in the caffeine and others are looking for the excellent aroma and taste that comes with an Arabica coffee. For those who only want enough caffeine to stay awake, Robusta coffee is cheaper and has a higher caffeine content. The reason that coffee house coffee is more expensive is that they use Arabica coffee beans from places like the Colombian coffee triangle. So, why is Arabica coffee expensive? Is it all about the market for better tasting coffee or is there more to the story?
Coffee Harvest for Arabica vs Robusta
Both Arabica and Robusta coffee plants take three to four years from when they are planted until they bear fruit. Both will typically keep producing coffee beans for twenty-five to thirty years and then taper off but potentially keep producing for up to fifty years or even more. During that time a Robusta coffee plant routinely outproduces an Arabica plant by about thirty to forty percent yield. This is assuming that both plants remain healthy and produce year after year.
Coffee Leaf Rust and Other Coffee Diseases
The British grew coffee on the island of Ceylon (now Sri Lanka) until the middle of the 19th century until a fungal disease killed all of the coffee plants which was when they switched to growing tea forcing much of the British public to become tea drinkers instead of coffee drinkers. Coffee leaf rust has wiped out vast areas of coffee production over the years spreading across the East Indies to Africa and in about 1950 to Brazil from where it spread bit by bit up through Colombia and into Central America and Mexico.
How Plant Diseases Like Leaf Rust Affect Coffee Prices
Developing newer varieties of Arabica that are cross bred from resistant strains and growing Arabica only at higher elevations where it is cooler have helped Arabica production recover but made Arabica more expensive to grow and more scarce. Climate change with progressively higher temperatures has driven Arabica production higher into the mountains also thus reducing output and driving prices up. Fortunately for Robusta coffee, it is resistant to coffee leaf rust and many other coffee plant diseases. Thus it can be grown at lower elevations and is not prone to having whole fields wiped out by plant disease. This makes Robusta cheaper to grow and maintain so the coffee farmer can sell at a lower price than Arabica and still make a profit.
The Market Determines the Price of Coffee
The eternal problem for coffee farmers in the mountains where coffee grows best is the same for farmers everywhere. When there is a great year with ideal weather, no new crop diseases, and, thus, a bumper crop, the price of their crop falls. This problem is often compounded by exchange rates. Coffee is priced in dollars and is quoted on the New York Mercantile Exchange. You can walk into coffee cooperative office in the heart of the Colombian coffee triangle and see a TV screen with up-to-the-minute price quotes in dollars and conversions to Colombian pesos. Every time Brazil has a bumper crop the price of Arabica falls and when they have drought and production falls the price goes up everywhere. Because Robusta can grow and produce in dryer conditions it is less prone to such variations in crop yield and thus less prone to such extreme price variations.
What Is Organic Coffee?
The pinnacle of the coffee world is organic coffee. So what is organic coffee? The organic label means that the coffee you are drinking was grown, processed, and stored according to sustainable agricultural practices and not mixed with coffee that does not meet this standard. The short version is that organic coffee is free from the roughly one hundred fifty impurities that can routinely be found in regular coffee grown by regular means. Roughly three percent of commercially available specialty coffee is organic.
Certification of Coffee As Organic
Coffee may be totally organic but you, the consumer, do not know that since you live in somewhere North of the coffee belt that is in the tropics. The coffee probably comes from near Manizales, Colombia, in the Colombian coffee belt, was likely grown around 8,000 feet altitude in rich volcanic soil and miles away from any nearby city. Luckily there are organizations that go to coffee farms and make sure that all of the boxes have been checked so that the coffee you are drinking is organic. The label on your bag of coffee says USDA Certified but the US Department of Agriculture delegates the certification job to local experts. The only coffee the US resident drink that is grown in the USA is grown in Hawaii where the USDA does the certifying.
Criteria for Organic Coffee Certification
Coffee falls under the same rules that the USDA uses for all organic foods. Here is what they say.
In order for coffee to get organic certification, the land it was grown on has to have been free of herbicides, pesticides, or synthetic fertilizers for three years or more and there has to be a buffer of land between the organic coffee crop and adjacent non-organic crops. This has to be demonstrated to the certifying agent before certification can be obtained. Additionally, organic coffee is processed, stored and shipped separate from other coffee.
Organic food is produced without using most conventional pesticides; fertilizers made with synthetic ingredients or sewage sludge; bioengineering; or ionizing radiation. Before a product can be labeled ‘organic,’ a Government-approved certifier inspects the farm where the food is grown to make sure the farmer is following all the rules necessary to meet USDA organic standards. Companies that handle or process organic food before it gets to your local supermarket or restaurant must be certified. Organic food is produced by farmers who emphasize the use of renewable resources and the conservation of soil and water to enhance environmental quality for future generations. Organic meat, poultry, eggs, and dairy products come from animals that are given no antibiotics or growth hormones.”
When you insist on the organic label for your coffee you can be assured that the coffee is high quality because nobody goes to all of the trouble of organic farming without producing a superior product. Thus, besides being free of impurities, grown according to strict standards, and processed to perfection, your coffee is Arabica of the highest quality.
Gourmet Organic Coffee
Besides organic coffees the other set of expensive coffees are gourmet coffees. May gourmet coffees are, in fact, grown organically. Thus they are free of impurities, tend to have higher levels of antioxidants, and generally taste a lot better than the average cup of coffee. As we noted, because organic growers put more effort into their crop much of that work results in gourmet quality coffee at the same time that it satisfies organic requirements.

Should You Drink Low Acid Coffee?
Coffee is the drink for a morning wakeup and afternoon pick me up. It has many health benefits. But what if coffee gives you heartburn or an upset stomach because of acid? Should you drink less coffee? Should you go with decaf? Should you drink low acid coffee? For that matter, what is low acid coffee?
Why Can Coffee Upset Your Stomach?
Drinking coffee can stimulate acid secretion in your stomach. This is because of the caffeine in your coffee. Going with a Colombian Arabica instead of a Robusta like Death Wish Coffee will help this. Then the coffee itself has acid content and, in fact, Arabica coffees with their high antioxidant content also are a bit more acidic. Roast makes a difference as light roast coffees are more acidic while a dark roast is less acidic. Espressos are less acidic than other coffees due to the short brewing time. And cold brewing results in a less acidic coffee as well.
Coffee Alternatives
You can find coffee brands that advertise lower acid content but remember that they have caffeine which will cause your stomach to secrete acid. Decaf coffee gets around the body’s secretion of acid and a dark roast reduces the coffee’s acid content. Cold brew, espresso are also alternatives. Drinking coffee that is not so strong and drinking fewer cups a day are reasonable approaches to reducing acid. In addition, avoid drinking a lot of coffee on an empty stomach as there is no food there to dilute the effects of the coffee. When you filter your coffee use a paper filter instead of metal as this traps some of the acid.
Chicory Coffee
At times when coffee has not been available people have used roots of the chicory plant to make a coffee substitute. The roots are roasted and ground and provide a non-acidic substitute for coffee. There are types of mushroom coffee that work in a similar fashion. While both of these get around the acid issue, they also eliminate real coffee from your diet.
Not All Heartburn Is Only Because of Coffee
Heartburn happens when acid from the stomach refluxes up into the esophagus. This happens because a band of muscle called a sphincter is not working properly. Many people who do not drink coffee and are careful with their diets need to take medicines like omeprazole (an acid blocker) to avoid having damage and a stricture in their esophagus. You probably do not want to be taking lots of drugs because you are drinking a dozen cups of coffee a day but if one or two cups causes problems ask your doctor about something for your acid reflux heartburn.
How about a Nice Cup of Tea?
Unfortunately, tea also contains caffeine and other chemicals that cause the stomach to secrete more acid. Pretty much any drink that gives you a boost like coffee does also tends to increase acid secretion. Using milk in your tea or coffee helps buffer some of that acid but too much cream (fat) can reverse that benefit by provoking more acid or bile secretion which does not get better with acid blockers!
In the end the best answer to the problem of too much coffee causing acid is to cut back on your coffee intake to where you are not getting heartburn.
Colombian Coffee Triangle
There are many excellent coffees in the world but the region where one can find universally excellent coffee in the greatest quantities is in the West of Colombia in the Paisa region of largely rural Colombia. This region is the coffee triangle but is also called the coffee growing axis (Eje Cafetero in Spanish). The region produces the majority of Colombia’s coffee and includes the departments of Caldas, Quindío, and Risaralda as well as the Northern regions of the Cauca Valley and Tolima. The main cities in this area are Manizales, Armenia, Pereira, and Ibagué.
Commercial Coffee Production in Colombia
Coffee production in Colombia was commercialized at the beginning of the 19th century with earliest coffee growing in the regions around the original Spanish missions. It was in the mid-19th century that the now-famous fourteen families traveled to the series of mountain ridges where Manizales is located today and began growing coffee in what became the heart of Colombian coffee production, the department of Caldas. Today the dominant departments for coffee production include Antioquia, Caldas, Cundinamarca, Huila, Nariño, Norte de Santander, Quindío, Risaralda, Tolima, and Valle del Cauca. Of these regions the greatest producers are still Caldas, Risaralda, Quindío and Tolima.
Why Does the Coffee Triangle Grow Great Coffee?
In the Colombian coffee triangle they only grow high quality Arabica coffee. Geographically this region is the Andean rainforest with temperatures ranging from 8 to 24 degrees Celsius. Rainfall is plentiful and the soil is rich and volcanic with the region lies just west of Colombia’s Northern Volcanic Front where the still-active volcano Nevada del Ruiz continually spews ash in a plume from its summit. Additionally, this region has not gone to overly mechanized coffee farming. This is partly because of the mountainous terrain but also because they simply produce better coffee with their grain by grain approach. The Juan Valdez character used in advertising Colombian coffee represents a Paisa coffee farmer from this region.
Coffee Culture Landscape World Heritage Site
This unique region was designated a world heritage site by the United Nations in 2011 which includes 18 urban areas and 6 sites within the coffee triangle. The specific areas were chosen as representative of different types of traditional coffee growing and culture. These include Riosucio, Pereira, Salamina, Calarcá and Armenia as well as smaller towns and coffee farms throughout rural, mountainous areas. As a result of this added attention to the region theme parks have been developed such as the Colombian National Coffee Park in Quindío as well as the Museum of Culture Coffee where various processes are demonstrated. These facilities also demonstrate aspects of traditional culture such as folk dances and celebrations.
Visiting the Colombian Coffee Triangle
For a foreigner who wants to visit the Colombian Coffee Triangle the best cities for setting up a “base camp” are Manizales followed by Pereira. Manizales can be reached by regional flights from Bogota as can Pereira and Pereira also has once a day evening flights from Panama. Manizales is a smaller city with a 400,000 population and our first choice for a visit. An ideal hotel with a spectacular view of the mountains and Nevada del Ruiz is the Caretero on Avenida Santander. Be aware that in neither Manizales nor Pereira or throughout the coffee triangle English is not commonly spoken and rarely understood so brush up on your Spanish or bring a pocket dictionary.
Where Does Your Coffee Come From?
Americans love their coffee. Although Northern European countries like Finland, Denmark, Sweden, and the Netherlands drink more coffee per capita the larger US population times a high consumption rate results in the US drinking more coffee than any other nation. Where does all of this coffee come from? The only state in the US that grows coffee is Hawaii so the US gets her coffee from the topical coffee belt that in the western hemisphere starts in Mexico and extends to Brazil. The two biggest producers in this region are Brazil which is the biggest producer of coffee overall and Colombia which is the biggest producer of Arabica coffee.
US Green Coffee Imports
The United States Department of Agriculture June 2022 pdf covering world markets and trade for coffee reports that the majority of imported unroasted coffee is Arabica of which the most is imported from Brazil followed by Colombia. Imports from these two nations have increased at the expense of imports from Mexico and Central America mostly because production has increased substantially in the two biggest South American producers.
Imports of Arabica Versus Robusta
Over the last decade the US has imported increasing amounts of Arabica coffee at the expense of Robusta with Arabica going from 68% of imports to 80% during those years. Because of inflation in the coffee market as well as everywhere else, Arabica prices are outpacing Robusta prices causing the USDA to speculate that US coffee roasters might start buying more Robusta and selling blends of Arabica and Robusta to remain competitive in pricing. Over the last decade Arabica imports went from 16.1 million bags a year to 19.4 million bags while Robusta fell from 3.5 million bags to 2.6 million bags.
Increased Coffee Imports from Brazil and Colombia
Over the last decade Brazil has increased its US market share from 29% to 36% while Colombia’s market share has gone from 17% to 23%. During this decade Mexico fell from an 8% share to 4% and Central America as a group fell from 25% to 23%. Because much of this reshuffling of market share came from increased Colombian and Brazilian production there could well be a trend reversal if Central America catches up. The report does not note the degree to which the Colombian civil war has cooled down and allowed production to resume in previously troubled regions.
World Coffee Production Increases
Production is up this year largely because of Brazil and the fact is that this is the “on” year of the two-year production cycle, important coffee growing regions are recovering from a severe frost in 2021 as well as drought. The increase is also being fueled by Brazil’s increasing production of Robusta going from 21.7 million bags to 22.8 million bags. Meanwhile production in Vietnam fell from last year’s record harvest to 30.8 million bags this year of which 95% is Robusta. Arabica production in Colombia will be flat this year as fertilizer shortages due to Russia’s war in Ukraine have limited potential gains. Production is estimated to come in at 13 million bags with 11.8 million to be exported to the USA.
Can Coffee Be Dangerous?
We have written extensively about the health benefits of drinking coffee. But we have to admit that there can be some negative aspects of drinking coffee as well. All of them have to do with drinking large amounts of coffee when you are already experiencing side effects of the stimulant aspects of caffeine. While the benefits of coffee seem to increase as you move up to as many as six cups a day, drinking more than that does not seem to help and is where many of the side effects lie. And some folks are simply more sensitive to the stimulant effects of caffeine. So, can coffee be dangerous? Here are a few examples.
When You Are Already Anxious More Coffee Is Not a Good Idea
A normal cup of coffee, eight ounces, contains ninety-five milligrams of caffeine. About 500 milligrams or five cups a day is commonly where caffeine starts to cause anxiety, stress, or depression according to the Journal of Pharmacology. If you are consuming 1,000 milligrams of caffeine a day or ten cups, they say that this is a reliable predictor of a higher level of anxiety than usual. There are many things in life that can cause you to be anxious but when evaluating why you are nervous think about how much coffee you are drinking.
When You Sleep Is Not Giving You Rest Ask What Role Coffee Has
A cup or two of coffee helps you wake up in the morning and keeps you going in the afternoon. However, six hours after you drink coffee half of the caffeine is still in your body. Twelve hours later a fourth still is hanging around. That means a fourth of your 2 pm coffee is still there at 2 am. If you have a nice espresso after supper at 8 pm half of that is still in your system at 2 am. People vary in terms of how fast their bodies metabolize (process) caffeine but if you find yourself staring at the dial of your alarm clock at 2 am consider limiting your coffee to mornings only and if that is not working, cutting your total consumption in half!
A Fast Heart Rate Can Be from Too Much Coffee
How a person’s heart responds to caffeine in the system varies from person to person. As much as two cups of coffee every five hours or even every hour has little effect on the heart rate for some people. For others a single cup of brewed coffee causes an irregular beat and a fast rhythm. If a person has a heart condition that affects their heart rate or regularity of their heart rhythm it is wise to discuss coffee intake with their treating physician. For the average person drinking a couple of cups of coffee a day this is not an issue.
Too Much Coffee Can Cause the Jitters
Some people get jittery when they drink too much coffee. This is an “overdose” of caffeine. Whether or not this happens to you depends on how much caffeine is in your coffee, how much coffee you drink, if you drink all of your daily coffee in a short time, and your innate sensitivity to caffeine. In addition to the jitters, too much caffeine can cause headaches, a fast heart rate, and trouble sleeping. Cutting back on your coffee intake will help but we suggest tapering off instead of going “cold turkey” as caffeine withdrawal causes headaches and fatigue and can last up to nine days.
Can Coffee Make You Feel Tired?
The caffeine in coffee is a stimulant. We use it to wake up and keep going. However, the body needs rest and when a person continually uses coffee to stay awake and keep going eventually the underlying fatigue overcomes even multiple cups of coffee and the person crashes. If you need to stay up for one night because of an emergency, using coffee as a stimulant is OK. But as a constant habit this will catch up with you and you need to time your coffee consumption so that you get uninterrupted sleep.

Is Juan Valdez a Real Guy?
You have probably seen him in the side of a package of coffee or on television. Juan Valdez is leading his burro who is in turn loaded with bags of coffee down out of the Andes Mountains in Colombia. When you see Juan Valdez on the label that means your coffee is 100% Colombian. So, is Juan Valdez a real guy? He has always been portrayed by a real person although not always Colombian and not necessarily someone in the business of growing or selling coffee.
History of Juan Valdez
Back in the 1950s coffee growers in Colombia wanted a way to distinguish their coffee from coffee produced elsewhere. Colombian coffee is uniformly very good Arabica coffee and commands a premium on the market. An American advertiser, William Bernbach, came up the idea of using a guy with a burro to emphasize the Colombian origin of the product. Thus, Juan Valdez was created. He was portrayed on TV and in print by a Cuban actor, José F. Duval, from 1958 to 1969. From 1969 to 2006 the role was taken by the Colombian actor Carlos José Sánchez Jaramillo with voice-overs, when necessary, by Norman Rose. Finally, in 2006 the Colombian Coffee Growers actually chose a Colombian coffee grower to play the part. Now Juan Valdez is played by Carlos Castañeda who is a real coffee grower from Andes, Antioquia, the department of Colombia where Medellin is located and in the Eje Cafetero.
What Does Juan Valdez On the Label Tell You?
There are lots of great coffees in the world. And Colombia is only the third ranking coffee producer after Brazil and Vietnam. However, Vietnam produces exclusively Robusta coffee and Brazil produces a substantial amount of Robusta. Thus, the biggest producer of Arabica coffee is Colombia. The fact of the matter is that the place in the entire world where you can most reliably find excellent Arabica coffee in is the Andes in the West of Colombia in the coffee growing axis, the Eje Cafetero. The climate with cool temperatures at high altitude, ample rain, excellent drainage, and rich volcanic soil combined with a multi-generational coffee growing culture to produce coffee that is routinely of the highest quality. The point of creating Juan Valdez was to provide a visual cue for coffee consumers that would lead them to always purchase the highest quality coffee from Colombia.
Juan Valdez Coffee Shops
A relatively recent addition to the Juan Valdez legacy is the chain of coffee shops with the Juan Valdez name. These are found primarily in Colombia but also throughout the Western Hemisphere. Juan Valdez coffee shops only serve Colombian coffee and feature coffees from specific departments such as Caldas, Huila, and Antioquia. They also feature organic coffees. Any of these can be ordered and brewed on the spot and customers can purchase bags of coffee from virtually any coffee growing region in the country. Juan Valdez coffee shops are popular meeting places and can be found in central regions of major cities, shopping malls, and even movie theater lobbies.

Update: Coffee and Diabetes
We have known for several years that coffee drinkers tend to have a lower risk of developing Type II diabetes. The Mayo Clinic website notes that the risk of developing diabetes is reduced by drinking coffee but that drinking coffee does not actually cure you if you have diabetes. The protective effect of drinking coffee increases up to about five to six cups a day and it’s the same for caffeinated and non-caffeinated coffee. Adding cream and sugar may tend to raise a person’s blood sugar momentarily but do not reverse the protective effect of not getting type II diabetes.
Drinking Coffee If You Have Diabetes
Polyphenols are the molecules in coffee with antioxidant properties. They are what help prevent type 2 diabetes, heart disease, cancers, and other diseases. In addition, the magnesium and chromium present in trace amounts in coffee also reduce type II diabetes risk. The risk reduction ranges from about 11% for one cup a day up to 17% for those who consume more than a cup a day. There is some evidence that in diabetics caffeine further reduces insulin sensitivity. Thus some experts suggest drinking decaf coffee. the best choice for diabetics who drink coffee is to use skim milk instead of cream, Splenda instead of sugar, or just plain black coffee.
Coffee Can Lower or Raise Blood Sugar in Diabetics
While the research is pretty clear that coffee drinkers are less likely to develop diabetes it is not clear in regard to whether in a specific individual with diabetes if coffee will lower or raise their blood sugar. The bottom line that we can discern from looking at research on this subject is that there are two different effects of coffee. Routinely drinking coffee has a strong tendency to reduce whatever factors drive a person to get type II diabetes and very likely continue to have this protective effect in diabetics. In other words, a type II diabetic will probably not get a worse case of their disease if they continue to drink coffee. The other effect is that by drinking coffee a type II diabetic may tend to temporarily either raise or lower their sugar.
Should a Type II Diabetic Quit Drinking Coffee?
If you are a diabetic you should be checking your blood sugar. As such, you will be able to see if your morning cup of black coffee raises or lowers your blood sugar. This is probably the most practical approach. For diabetics who already have complications such as retinal or kidney disease the wise approach is to ask your doctor what to do and to strictly follow their advice. Because there is some evidence that diabetics who drink coffee experience a drop in their blood sugar this is beneficial and, as we noted, there appears to be a long-term benefit of coffee drinking even in those who are now diagnosed as having type II diabetes.
Medium Roasted Coffee for Maximum Phenol Content
Since it is the polyphenols that provide the most protection against developing type II diabetes which coffee gives you that benefit? Medium roasted coffee provides the greatest phenol levels, and the best coffees are Arabicas like Coffee from Colombia!

Who Invented Coffee?
The coffee plant is native to East Africa where it still grows in its original home in the forest of the Ethiopian plateau. Thus the plant was not invented but grows naturally. However, it did take a person to roast coffee beans and brew coffee. No one really knows how coffee made it from being an upland forest plant to the most popular drink on the planet but the story goes that a goat herder named Kaldi saw his goats eating the beans of the coffee plant, getting excited, seeming to enjoy them, and not sleeping at night. The story continues that Kaldi brought berries to a nearby monastery where the abbot experimented with the berries and discovered that roasting, grinding and brewing the beans resulted in coffee as we know it. Thus the person who invented coffee in its original form was someone like the abbot in the story who first brewed coffee.
Who Invented the Coffee Business?
No matter which individual or individuals came up with the idea of roasting coffee, grinding it, and brewing it to make a cup of coffee, it would have been a local beverage in the highlands of Ethiopia without commercialization of coffee on the Arabian Peninsula in 1400s in what is today the country of Yemen. A century later trade within the Ottoman Empire had taken coffee to Persia, Syria, Egypt, and the seat of the Empire in what is today the country of Turkey. It took another hundred years for coffee to be consumed in Europe. By that time Dutch traders were planting coffee throughout the East Indies and Spanish colonials were planting it in the New World.
Who Invented The French Press?
At the seat of the Ottoman Empire coffee was made using an Ibrik. Coffee grounds were boiled just like they are for making Turkish coffee today. Over time people came up with different methods for brewing coffee. The French Press came into being in the middle of the 19th century and both the French and the Italians claim credit for inventing this method for making coffee. This method remains popular today because it is cost-effective and gives a person better control over the taste of the coffee.
Who Invented the Automatic Coffeemaker?
By the twentieth century coffee makers arrived in which boiling water was poured or dripped over coffee grounds which got rid of the problem of having grounds mixed with the coffee after boiling the coffee grounds with the coffee. Electric percolators allowed for commercial quantities of coffee to be made for restaurants or large kitchens serving many people.
Who Invented Vacuum Packed Coffee?
By the turn of the 19th to 20th century it became popular to buy roasted and ground coffee instead of buying whole beans and grinding them. In order to preserve freshness of ground coffee on the shelf the Hills Brothers invented a method of vacuum packing their coffee so all of the air was sucked out of the can of coffee before it was sealed.
K-Cup Invented in 1992
The idea of single serve coffee started with Ernesto Illy who created pre-measured espresso pods in 1974. It was 18 more years before Green Mountain invented the K-cup and so the history of invention in the world of coffee continues after hundreds of years from when coffee crossed from Africa to the Arabian Peninsula and then spread around the world.

Does Coffee Cause Dehydration?
We drink coffee to wake up in the morning and to keep going in the afternoon. We drink coffee because we like it. The wakeup part of coffee comes from caffeine which also acts as a diuretic. That is, caffeine causes your kidneys to produce more urine. So, if you drink lots of coffee does coffee cause dehydration? The quick, short answer is that if you drink lots of coffee that has lots of caffeine you will lose more water than you take in with the coffee.
Metabolism and Effects of Coffee
When you drink coffee, it passes into the intestinal tract and is absorbed into the blood stream. The many health antioxidants in coffee serve to decrease inflammation, reduce the likelihood of Type II diabetes, cut back on your chances of getting Alzheimer’s, and even decrease the risks of various cancers. Caffeine goes to the brain where it serves to wake us up and when it passes through the kidneys it stimulates increased urine formation. The direct effect of caffeine is that it increases blood flow to the kidneys which in turn ups urine creation. This effect has the potential to cause dehydration. Does it?
How Much Coffee Does It Take to Cause Dehydration?
Coffee contains water so it should hydrate our bodies. Caffeine causes excessive urination which should cause dehydration. The key to the question of how much coffee it takes to dehydrate a person has to do with getting enough caffeine to overcome the water that one drinks with the coffee. Thus, stronger coffees are more likely to dehydrate than weaker ones and one needs to drink enough coffee to get enough caffeine to get the dehydration effect. How much is that? Studies have shown that a person of average size needs to ingest at least 500 mg of caffeine to get enough diuretic effect to overcome the amount of water they ingest with their coffee. Because an average cup of brewed coffee contains 90 mg of caffeine this means you need to drink more than five and a half cups of coffee a day to lose more water from your coffee drinking than you take in as part of the coffee.
Caffeine Content of Various Types of Coffee
Brewed coffee is the kind that most people drink. This includes using a percolator, pour over coffee, or a French press. The amount of caffeine in an eight ounce cup of brewed coffee ranges from seventy to one hundred forty milligrams with ninety milligrams being the average. Robusta coffee has a higher caffeine content than Arabica coffee from Colombia so you can drink more Colombian coffee than Death Wish coffee before you have to worry about dehydration.
Caffeine In Instant Coffee
Convenient instant coffee generally has less caffeine than brewed coffee ranging from thirty to ninety milligrams per eight ounce serving. So, if avoidance of dehydration is your only goal you can drink more instant coffee than brewed and accomplish your goal.
Caffeine In Espresso
A shot of espresso carries on average sixty-three milligrams of caffeine. Of course the volume of water is lower as well as thirty to fifty milliliters. However, the concentration of caffeine in espresso is as much as five times stronger than in brewed coffee.
Decaf coffee contains no more than seven milligrams of caffeine in an eight ounce cup so if your only goal is avoiding dehydration this is the next best step to drinking a glass of water!
You Need To Drink Lots of Strong Coffee To Achieve Dehydration
The bottom line to our question about dehydration is that you need to drink at least nine shots of espresso or about five and a half cups of brewed coffee for the amount of caffeine that you ingest to cause you to lose more water through your kidneys than you take in with the coffee. The amount of coffee goes down to around three cups a day if you are only drinking strong Robusta coffee.
