Hong Yun

The less famous sibling of Ruby 18, crossing Kyang assamica with an Indian Jaipuri plant. It gives a rounder, fruitier black tea without the menthol signature, and is planted far less widely.

What the plant is like

Worth knowing mainly because it is the honest answer to 'is there Taiwanese black tea that does not taste of mint'.

What it is usually made into

The categories this cultivar is typically processed into. It is a statement about common practice, not a limit — processing decides the category, and a cultivar can be taken down more than one route.

  • Black teaTea taken deliberately through full enzymatic oxidation, giving the dark leaf, amber-to-red liquor and malty or brisk character most Western drinkers think of as simply 'tea'.

  • Hong Yu (Ruby 18) vs Hong Yun (Ruby 21)Taiwanese black tea became distinctive rather than derivative because of one cross, and that cross produces a natural menthol-and-cinnamon aroma nobody believes is natural. Its less famous sibling is the answer for anyone who does not want it.
