Black
Taiwan
Taiwan's black teas are defined by cultivar character more than any other black-tea family. Ruby 18 (Hong Yu) carries a signature cinnamon-menthol note that makes it immediately identifiable and unlike any Indian or Chinese black; it was bred from a wild Taiwanese assamica crossed with a Burmese assamica. The broader Hong Cha category covers other local-cultivar blacks that are typically lighter and more aromatic than Himalayan-tradition blacks. For a drinker familiar with Darjeeling or Assam, Taiwanese blacks are a genuinely different experience.
Taiwan's blacks are all about the cultivar, and Ruby 18 is the showstopper: that cinnamon-and-menthol signature is unlike any other black tea on Earth. If you only know Assam and Darjeeling, this family will genuinely surprise you, which is half of why I keep coming back to it.
