**I. Brewing Logic: Balancing Roast & Rock Essence**
1. Tea Awakening
• *Dry Awakening*:
◦ New tea: Spread on ceramic plate for 24 hrs to mellow roast.
◦ Aged tea (3+ yrs): Store in Yixing clay jars for 1 week to revive aged notes.
• *Wet Awakening*:
◦ Light roast: 95°C (203°F) flash rinse (3 sec).
◦ Heavy roast: 100°C (212°F) 10-sec "steam shock" to unlock caramelization.
2. Temperature Gradients
• *Standard*: 98-100°C (208-212°F) to penetrate roast layers.
• *Exceptions*:
◦ Rare cultivars (White Cockscomb): 95°C (203°F) first 3 brews → 100°C after.
◦ Aged Shui Xian: 100°C + iron kettle boiling to activate woody depth.
3. Tea-to-Water Ratios
• *Gaiwan Standard*: 8g per 110ml (1:13.75); bold leaves (e.g., Rou Gui) use 9g.
• *Clay Pot Adjustment*: Reduce by 0.5g in Zhu Ni pots to avoid astringency.
4. Pouring Dynamics
• *High-Altitude Pour*: 15cm (6") height, thick stream for tightly rolled leaves (Iron Arhat).
• *Circular Low Pour*: Edge-hugging flow for open-leaf types (Buddha’s Hand).
5. Steeping Timeline
• *Light Roast (Floral)*:
◦ Brews 1-3: 5-sec flashes for orchid notes.
◦ Brews 4-6: 15→25→35 sec for pectin sweetness.
◦ Brews 7+: 60 sec to extract mineral base.
• *Heavy Roast (Caramel)*:
◦ Brews 1-3: 10 sec.
◦ Brews 4-6: 20 sec.
◦ Brews 7+: +30 sec per round.

**II. Vessel Science**
1. Thin-Wall Zhu Ni Pot (Core Tool)
• *Thermal Control*: 1.5mm walls balance roast intensity.
• *Shapes*:
◦ Pear-shaped: Maximizes aroma for fragrant Rou Gui.
◦ Flat-top: Broad space for aged Shui Xian expansion.
2. Blue-White Porcelain Gaiwan (Precision)
• *Heat Stability*: 2-3mm thickness prevents temp drops.
• *Observation Window*: 8.5cm diameter monitors leaf unfurling.
3. Woodfire Clay Pot (Aged Tea)
• *Taming Power*: Micro-pores soften astringency in 10+ year teas (e.g., 1990s Iron Arhat).
4. Silver Kettle (Niche Use)
• *Water Softening*: Silver ions enhance Hui Yuan "mossy" minerality.
• *Avoid*: Heavy-roast teas to prevent amplified harshness.

**III. Advanced Techniques**
1. Roast-Level Optimization
• *Light Roast*: Open lid 3 sec post-pour to protect florals.
• *Medium-Heavy Roast*: Crack lid 0.5mm after pours to vent roast.
2. Terroir Enhancement
• *Ravine-Grown*: 98°C (208°F) spring water + silver kettle for cooling sensation.
• *Cliff-Top*: Mineral water + Zhu Ni pot at 100°C to emphasize boldness.
3. Blending Science
• *Varietal Layering*: Top with floral types (Yellow Rose), base with rich Shui Xian.
• *Aging Blends*: 3:7 new (aroma) to aged (depth) ratio.

**IV. Myth-Busting**
✘ "Boiling water mandatory": Small-leaf types (Rui Xiang) need 95°C (203°F) protection.
✘ "Fast pours lack depth": 10-sec first brew highlights Ma Tou Yan Rou Gui’s spice.
✘ "Yixing is best": Delicate Que She tastes better in porcelain.

**V. Adaptive Brewing Framework**
Tailor by roast level, terroir, and age:
• *Light Roast + Zhengyan + Young Bush*: 95°C (203°F) / porcelain gaiwan / fast pours.
• *Heavy Roast + Ravine + Old Bush*: 100°C (212°F) / Zhu Ni pot / slow extraction.
• *Medium Roast + Danxia + Blends*: 98°C (208°F) / woodfire pot / staged steeping.

Wuyi rock tea brewing is a duel between fire and water, aroma and essence. By controlling catechin (astringency), theaflavin (brightness), and pectin (body) extraction, its "fragrant, clear, sweet, lively" rock essence unfolds. Master the Three-Observation Rule:
1. Leaf Expansion → Adjust temp.
2. Liquor Clarity → Time steeps.
3. Cup-Bottom Aroma → Choose vessels.
This transforms each brew into a geological poem written in tea liquor.
