How much caffeine is in Keemun Hao Ya Black Tea?

Each 8 oz cup (240ml) serving contains approximately 48 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 Keemun Hao Ya Black 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 Keemun Hao Ya Black Tea be extracted?

Extract for 2:30-3:30 using Gaiwan, at a ratio of 12g/L (3g leaves to 240g water), prepared at Whole Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Keemun Hao Ya Black 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 Keemun Hao Ya Black Tea?

Caffeine and serving strength vary with dose, preparation, and individual sensitivity. Use individualized medical 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.

Where it sits

Stronger than 164 of the 345 other drinks in the catalogue, and weaker than 169.

That is 48 mg in a 8 oz cup (240ml) serving — a concentration of 20 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.
