Served strong without sweeteners, drenched in cream, flavored with fruits, or blended with citrus oils, black tea is one of the most popular brews in the United States and abroad. When compared to other varieties, black tea undergoes a lengthier oxidization process, which produces stronger flavors and more caffeine than less oxidized selections. Black tea also retains its flavor for several years, unlike green tea, which typically loses its taste within a year. From worldwide classics to exotic blends, below you will find 10 variations of black tea to add to your tea-drinking repertoire.
