Decaf tea is any tea that has undergone a process which eliminates most of the caffeine content. Two processes are currently used to commercially decaffeinate tea, an ethyl acetate and a CO2 method. While the ethyl acetate method is cheaper and easier, the CO2 method has been proven much safer. Decaf tea is the perfect alternative for tea lovers who are trying to lower their caffeine intake. Adagio Teas continues to sell the finest loose decaf tea you'll find, and now offers one variety in a convenient gourmet tea bag as well.
