Black Tea is just tea and although the leaves in the tea bag are black, the tea fluid is the same old color as regular tea. It tastes the same as regular tea as well. Lack tealeaves are dried and fermented, which gives the tea a darker color and richer flavor than green tea (which does not undergo the fermentation process).
Depending on how strong it's brewed, black tea contains about 50 mg of caffeine per cup. (green tea contains 8 to 30 mg per cup, while coffee contains 100 to 350 mg.)
But I don’t drink it as a pick-me-up I drink it for its benefits. Black tea contains a number of antioxidants, which are compounds that help the body fight free radicals although early research on black tea's cardiovascular benefits has yielded mixed results but in a laboratory study published in 2009, scientists discovered that compounds extracted from black tea were more effective at slowing the absorption of blood sugar than those extracted from green tea and oolong tea. Additionally, a 2009 population study of 1,040 elderly adults found that long-term intake of black and/or green tea was associated with lower prevalence of diabetes.
