Question: what is the difference between caffeine free and decaffeinated?
Answer: The decaffeination process leaves a minute amount of caffeine in the leaf. By law, tea labeled as “decaffeinated” must have less than 2.5 percent of its original caffeine level, which usually equates to less than 2 mg per cup. "Caffeine-free" refers to a product that never contained caffeine to begin with.
