Black teas have been the favorite of American and British tea drinkers for many years. Earl Grey, breakfast teas and even the masala chai native to India are a few of the blends with which you may be most familiar.

Like white, green and oolong tea, black tea comes from the camelilia sinensis plant and does contain caffeine. It is also the most highly processed; the leaves are withered, rolled and fermented prior to being heated. Like other teas, it offers a variety of healthy polypheonols, or antioxidants, and helps to boost the immune system as well as potentially prevent certain types of cancer.
