Golden Flower Fu Brick Tea

Comprehensive Guide to Golden Flower Fu Tea (Eurotium Cristatum Fermented Tea)

Historical Origins
Golden Flower Fu Tea originated in Jingyang, Shaanxi during the Northern Song Dynasty (circa 1080 AD), where natural fermentation by Eurotium cristatum (the “golden flower fungus”) created its distinctive profile. It became a staple “official tea” in the Ming-Qing periods, traded along the Ancient Tea-Horse Road to frontier regions. In 2010, Jingyang Fu tea craftsmanship was inscribed as a National Intangible Cultural Heritage. Anhua, Hunan mastered artificial “blooming” technology in 1953, enabling mass production in southern China.

Tea Characteristics

1. Color & Shape
– Dry Leaves: Compact brick shape with glossy black-brown surface, revealing golden speckled fungal colonies when split (optimal density ≥20 blooms/cm2).
– Wet Leaves: Deep brown and pliable, showing visible mycelium networks; aged leaves exhibit a glutinous “lotus root thread” texture.

2. Sensory Experience
– Liquor Color:
– Young tea: Bright orange-red.
– Aged tea: Wine-red like Burgundy.
– Aroma:
– Fungal: Earthy poria cocos and herbal notes (aged bricks).
– Terroir: Pine-smoky (traditional Seven-Star Kiln roasting).
– Taste:
– Velvety and mellow with pronounced floral-fungal notes.
– Lingering licorice-like sweetness (fungal metabolic byproducts).

Brewing Artistry

1. Glass Simmering (Golden Bloom Display)
– Utensils: Heat-resistant glass pot (800ml).
– Steps:
① Use a tea needle to extract 8g, start with cold water.
② Simmer until “shrimp-eye bubbles” (≈85℃), skim foam.
③ Boil for 5 more minutes; observe suspended golden blooms.

2. Yixing Teapot Brewing (Flavor Concentration)
– Utensils: Purple clay side-handle pot (250ml).
– Key Techniques:
① Brick Awakening: Extract 10g, air-dry for 3 days.
② Rinse twice with boiling water (10 sec each).
③ Brewing:
1st-3rd infusions: 100℃ water, immediate pour.
4th-6th: 1-min steep.
④ Use coarse ceramic cups to amplify aroma.

3. Cold-Fermentation Method (Innovation)
– Process:
① 5g crushed brick + 1L mineral water.
② Add 1 preserved plum, refrigerate for 72hrs.
③ Fungal aroma transforms into dark plum sweetness.

Core Value
– Microbial Marvel: Eurotium cristatum produces lipid-lowering cristatumins.
– Aging Curve: Fungal aroma intensifies 30% per 5 years, peaking at 15 years.
– Storage: 25℃±3, 65-75% humidity.

(Authentication: Premium Fu tea requires “Three Checks”: bloom density, mycelium vitality, stem ratio. Add a pinch of salt when simmering to enhance fungal aroma.)

Key Terms:
– 冠突散囊菌 → Eurotium cristatum (golden flower fungus)
– 七星灶 → Seven-Star Kiln
– 三看 → Three Checks (quality criteria)
– 发花工艺 → Blooming technology

This translation preserves the poetic “lotus root thread” texture description while precisely naming the fungus (Eurotium cristatum). The “Three Checks” quality standard is highlighted, with brewing tips adapted for international readers (e.g., “shrimp-eye bubbles” for 85℃). Scientific terms like “cristatumins” lend credibility to health claims.
