Why Does Dan Cong Tea Need Quick Infusion to Avoid Bitterness?
Dan Cong tea, produced in Fenghuang Mountain, Guangdong, is renowned for its rich aroma and distinctive mountain character. However, many tea lovers experience bitterness when brewing it, often due to slow pouring. This is closely related to the tea's characteristics.
Characteristics of Dan Cong Tea
Dan Cong is a semi-fermented oolong with tender leaves and a striped shape, allowing rapid release of compounds during brewing. If steeped too long, polyphenols and caffeine dissolve excessively, causing bitterness and astringency.
- Polyphenols: contribute astringency and bitterness; excess leads to harshness.
- Caffeine: main source of bitterness; more is released with longer steeping.
- Aroma compounds: have low boiling points; prolonged steeping causes them to evaporate, weakening the fragrance.
The Science Behind Quick Pouring
Quick pouring controls the extraction rate, balancing aroma and taste in the first few infusions. In a short time, aromatic compounds and sweet amino acids are released first, while bitter components remain undissolved, resulting in a fresh, mellow cup.
- First 3 infusions: pour out within 5-10 seconds to enjoy the floral aroma and mountain notes.
- Infusions 4-6: extend to 15-20 seconds; the flavor strengthens but remains smooth.
- After 7 infusions: adjust to taste, but avoid exceeding 30 seconds to prevent bitterness.
Practical Brewing Tips
- Water temperature: use 95-100°C boiling water to release aroma.
- Tea amount: about 7-8 grams, best in a gaiwan or purple clay pot.
- Pouring water: pour gently along the wall, avoiding direct hitting of the leaves to reduce agitation.
- Draining: pour out completely and quickly, leaving no residual water to prevent over-extraction.
Mastering the rhythm of quick pouring allows you to enjoy the perfect balance of fragrance, sweetness, and aftertaste in Dan Cong tea.
