History

Liu An Basket Tea (六安篮茶) is one of China's most distinctive and rare dark teas, originating from Qimen (Keemun) county in Anhui province - the same region famous for Keemun black tea. The tea is packed into small bamboo baskets lined with bamboo leaves and aged for years or decades, during which it undergoes slow post-fermentation. Historically, it was shipped to Southeast Asia (particularly Hong Kong, Malaysia, and Vietnam) where overseas Chinese communities prized it as a household medicine and daily drink. Cantonese families traditionally kept Liu An in their medicine cabinets, using it to treat digestive complaints, sore throats, and fevers. Vintage Liu An baskets from the 1950s–1970s are now highly collectible.

Processing

The base tea is a sun-dried green tea from Qimen's local cultivar. After initial processing, the leaves are steamed and packed tightly into small bamboo baskets (approximately 500g each), lined with fresh bamboo leaves. The baskets are sealed and stored for aging - during which natural microbial fermentation slowly transforms the tea. The bamboo imparts its own subtle flavor. Authentic Liu An must be aged a minimum of 3–5 years, with 10–30 year aged versions being most prized.

Tasting Notes

Appearance

Dark, compact leaves with a slightly reddish-brown hue, often with visible bamboo leaf fragments. The liquor is a clear, deep amber-red - lighter than pu-erh but darker than most black teas.

Aroma

Distinctively medicinal and herbaceous - ginseng, bamboo, dried herbs, and a subtle camphor coolness. The bamboo basket imparts a unique green, woody note. Older baskets develop a deeper, more complex medicinal character.

Taste

Smooth, clean, and subtly sweet with a distinctive medicinal-herbal character. The bamboo basket aging gives it a unique 'green' quality unlike any other dark tea. The mouthfeel is clean and refreshing despite its dark color. Old Liu An has a remarkable cooling sensation in the throat.

Brewing Guide

Western Style

  • Leaf: 4g per 200ml
  • Water: 100°C (212°F)
  • Time: 1–2 minutes
  • Infusions: 6–10 infusions

Gongfu Style

  • Leaf: 6g per 100ml
  • Water: 100°C (212°F)
  • Time: 10s first, +5s each subsequent
  • Infusions: 10–15 infusions

Step-by-step

  1. Break the basket carefully. Gently pry apart the compressed tea from the bamboo basket. Don't shatter the leaves - try to separate them as intact as possible. Tip: A tea pick or letter opener works well. Some drinkers keep the leaves in large pieces for slower extraction.
  2. Rinse twice. Two quick rinse steeps (5 seconds each) to remove storage dust and wake up the aged leaves. Tip: The rinse water should smell herbaceous and clean - any musty smell indicates poor storage.
  3. Use full boiling water. 100°C throughout. Aged dark tea needs maximum heat to open up. Tip: Yixing clay teapot is ideal - it retains heat and complements the tea's earthy character.
  4. Short, patient steeps. Start at 10 seconds, extend gradually. Liu An releases flavor slowly and evenly over many infusions. Tip: The medicinal character emerges most clearly in steeps 3–6. Later steeps become sweeter.
