How do you produce decaffeinated coffee organically?
Caffeine can be extracted using solvents such as methylene chloride or ethyl acetate. The latter is better than the former from health and environmental aspects but neither would be allowed for organic. There are two further processes. One is decaffeination using carbon filtration and the other uses liquid Carbon dioxide. As activated carbon and Carbon dioxide are both allowed as processing aids in organic production these processes may be used. The former is known as the Swiss water process and is the most common for organic coffee.
