"Black Tea" is a fully oxidized tea made from the leaves of Camellia sinensis, enjoyed hot or iced worldwide. Its dark color and robust, malty or brisk flavor come from polyphenols transformed during oxidation. Naturally containing caffeine and L-theanine, it can support alertness while still feeling smooth and steady for many people. Sipped plain or with a splash of milk, black tea offers a low-calorie way to add flavor, warmth, and hydration to daily routines.
