All the benefits of tea – with none of the caffeine. We carry a wide variety of decaf tea and caffeine free herbal teas, from favorites like rooibos chai to some of the best chamomile tea. Do herbal teas have caffeine and have you ever wondered what the difference is between decaf and caffeine-free? Decaf Teas are created through a completely natural CO2 pressurization process, which removes caffeine from tea leaves. It’s impossible to remove all traces of caffeine from the tea leaves and as a result, decaf tea contains about 5-10 mg of caffeine per cup (regular tea contains approximately 50 mg of caffeine per cup). Caffeine-Free teas (herbals or tisanes) contain ingredients that are naturally free of caffeine.
