All true teas contain caffeine. Decaffeinated teas are leaves from the plant Camellia sinensis that have had at least 97.5% of the caffeine removed. The term “decaffeinated” is different from “caffeine free.” Decaffeinated refers to a product that originally contained caffeine (like Camellia sinensis) and underwent a process to remove most of its caffeine content. Caffeine-free, on the other hand, refers to a product (like many of our herbal teas) that never contained caffeine to begin with. For our decaf teas, we exclusively use the carbon dioxide (CO2) method of decaffeination. We believe this is the safest form of decaffeination, and retains the greatest flavor and health benefits.
