Hei Cha

Hei cha is the only tea category where leaves go through true fermentation, a slow bacterial process that transforms the leaf, after drying. That process gives each tea a deep, mineral character unlike anything else. If you enjoy deep, woody flavors, or already drink Pu-erh, start here. Our guide to dark tea covers the full range of styles. The collection features aged, pressed dark teas with rich, mellow flavor developed over years of natural change.

Most hei cha is pressed into bricks, logs, or columns and aged for years before drinking. The flavor leans towards dates, dry wood, and sometimes a grain-like warmth, with a sweet undertone that deepens over time. Texture stands out too: a well-aged dark tea feels dense and soft on the palate, almost syrupy. For the oldest pressings we carry, our aged teas collection goes deeper. Brewing is simple and tolerant of long steeps, so this is an easy style to explore at any level.
