How much caffeine is in Tianjian Fu Zhuan Dark Tea?

Each 8 oz cup (240ml) serving contains approximately 34 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 Tianjian Fu Zhuan Dark Tea?

Target 95°C (203°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Tianjian Fu Zhuan Dark Tea be extracted?

Extract for 0:30-3:00 depending on infusion style using Gaiwan / Boiling, at a ratio of 10g leaves per Liter of water, prepared at Compressed Leaf or Whole Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Tianjian Fu Zhuan Dark Tea 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 Tianjian Fu Zhuan Dark Tea?

Caffeine and serving strength vary with dose, preparation, and individual sensitivity. Use individualized guidance for pregnancy, medication interactions, allergies, reflux, or other health concerns. This is general educational information, not medical advice — consult a qualified healthcare professional about your own circumstances.

That is 34 mg in a 8 oz cup (240ml) serving — a concentration of 14.2 mg per 100 ml. The scale above ranks whole servings, and servings differ in size, so a larger drink can sit further right while being weaker cup for cup.
