What is Dark Tea?
Post-fermented and microbially transformed for deep, earthy character - 13 varieties.
Dark tea (Hei Cha) is a broad category of post-fermented teas produced across several Chinese provinces. Unlike pu-erh, these teas undergo distinct microbial fermentation processes specific to their region. Historically compressed into bricks and traded along the Tea Horse Road to Tibet and Central Asia, dark teas remain essential to the dietary traditions of China's northwestern minorities.
How dark tea is made
Steps: Kill-green → Roll → Pile & Ferment → Dry → Press
Dark tea's microbial fermentation is driven by specific fungi and bacteria - most notably Eurotium cristatum in Fu Zhuan, which produces the distinctive golden flowers visible in aged bricks.
