Decaffeinated Tea refers to black or green tea that has had most of its natural caffeine removed. It's important to note that decaffeinated does not mean caffeine-free . There is still a small amount of caffeine in most decaffeinated teas unless the product is highly processed. Decaffeinated Black Tea can contain about 4-6mg of caffeine per tea bag. Decaffeinated Green Tea can contain about 2-4mg of caffeine per tea bag. Tea quality and steep time will also influence the amount of caffeine in decaffeinated tea. The Journal of Food Science independently tested Stash Premium Decaffeinated Green Tea and found that it contained 7.6mg of caffeine per 2 grams of tea leaves.
