All of our English Tea Store loose leaf black teas are made from Ceylon tea, high grown in estates 5500 feet above sea level. Natural flavoring is added to infuse each blend with a distinct flavor. Each, in 4 oz. or 16 oz. sizes, is packaged in a vapor-proof triple-layer bag. Some of our naturally-flavored black teas include peach, Brazilian guava, Arctic raspberry, black forest, and coconut.
