黑茶生产历史悠久,是我国特有的茶类,属于后发酵茶,经杀青、初揉、渥堆、复揉、干燥五道基本工序初制而成,利用菌发酵的方式制成。由于黑茶的原料粗老,制造过程中往往要堆积发酵较长时间,叶片大多呈现暗褐色,因此被人们称为“黑茶”。又因其主要供边区少数民族饮用,所以也被称为边销茶。 Black tea has a long history of production. It is a kind of tea unique to China. It belongs to post-fermented tea.

Because of its main supply for the ethnic minorities in the border region, it is also known as side pin tea.
