Yogi teas are packaged to preserve freshness and quality for up to two years in a variety of shipping and storage conditions. To ensure maximum flavor and freshness for our consumers, Yogi teas are stamped with a Best Before date, which indicates two years from the date of manufacture. Yogi teas are perfectly safe to enjoy outside of the Best Before window; however, you may notice a difference in potency or flavor after that time. You can find the Best Before date on your tea carton, located on the same side as the yoga pose.
