How much caffeine is in China Yixing Zi Sha Hong Cha?

Each 5–6 oz cup (150–180 ml) serving contains approximately 44 mg of caffeine. For comparison, a standard 8 oz cup of brewed drip coffee contains around 95 mg. Actual content varies with dose, water temperature, and contact time.

What temperature should I use for China Yixing Zi Sha Hong Cha?

Target 90°C (194°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should China Yixing Zi Sha Hong Cha be extracted?

Extract for 1.5–2.5 min using Yixing Zisha Pot or Gaiwan, at a ratio of 3–4g per 150ml water, prepared at Curled / Orthodox. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my China Yixing Zi Sha Hong Cha taste bitter?

Bitterness almost always indicates over-extraction. Shorten the contact time, lower the water temperature slightly, or use less leaf. Change one variable at a time so you can tell which one was responsible.

Who should avoid China Yixing Zi Sha Hong Cha?

Caffeine sensitivity: moderate; avoid before sleep. Iron absorption: low-level tannins; minimal concern. Pregnancy: 200 mg/day caffeine ceiling. This is general educational information, not medical advice — consult a qualified healthcare professional about your own circumstances.
