Coffee Bloom

What is a coffee bloom and is it a good or bad thing? The coffee bloom is the release of carbon dioxide gas when hot water is poured over ground coffee beans. Carbon dioxide gas is trapped inside coffee beans when they are roasted. Darker roasts contain more carbon dioxide and lighter roasts contain less. Roasted whole beans retain the carbon dioxide longer than roasted and ground coffee and storing in a cool environment keeps the carbon dioxide longer. The antioxidant compounds that give coffee its health benefits and flavor are trapped in the carbon dioxide as well.

More Carbon Dioxide, More Bloom, More Flavor and Better for You

Store your coffee as green beans if you have the ability to roast. Store them as roasted whole beans otherwise. Store in a cool and dry location and grind just enough coffee just before brewing. Doing all of this will give you a bigger coffee bloom when you add water and better flavor and health benefits as well. It all has to do with the antioxidants after all.

Antioxidants

Regular and organic coffee antioxidants are good for you and are what give coffee its flavor.

So, just what are antioxidants and why should we want to have more of them? Scientifically an antioxidant is a molecule that inhibits the cell damage and cell death in human cells caused by oxidative breakdown of other molecule in the cell. Oxidation is a factor in sickness and aging. Antioxidants help prevent the damage caused by excessive oxidation and to a degree inhibit the aging process. When an oxidative reaction brought on by disease gets going it produces free radicals that start chain reactions which in turn cause cell and tissue damage. The human body has or uses antioxidants to control this situation. Natural means of controlling oxidation include vitamins C and E as well as glutathione. It is low levels of antioxidants that can lead to a condition referred to as oxidative stress and resultant damage to cells in the body. Organic coffee antioxidants are in the same class of molecules that help reduce oxidation.

So, when you see a substantial coffee bloom you know that you have stored your coffee correctly and that your coffee is full of healthy antioxidants. What are some of the health benefits of antioxidants?

Less Cancer, Less Diabetes and Fewer Neurological Degenerative Diseases

Drinking coffee is associated with a lower incidence of several forms of cancer. People who drink four to six cups of coffee a day experience half the incidence of Type II diabetes. And coffee drinkers are less prone to Alzheimer’s disease and Parkinson’s disease. It appears to be all about the antioxidants. And preserving these antioxidants is good for you.

More about the Coffee Bloom

When you store roasted coffee, it releases carbon dioxide or degases. That is to say the gas inside the bean seeps out. This goes faster in heat and slower in cold.  When you pour hot water over your freshly ground coffee the pleasant aroma and foam on top of the coffee is the coffee bloom, a sign of great fresh coffee.
