How much caffeine is in Fu Zhuan Dark Tea Brick?

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 Fu Zhuan Dark Tea Brick?

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 Fu Zhuan Dark Tea Brick 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 Fu Zhuan Dark Tea Brick 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 Fu Zhuan Dark Tea Brick?

Fermentation depth, acidity, and caffeine vary by product and preparation. Post-fermented tea is not alcoholic. 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.
