How much caffeine is in Alishan High Mountain Oolong?

Each 6 oz Gongfu serving (180ml) serving contains approximately 35 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 Alishan High Mountain Oolong?

Target 92°C (198°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Alishan High Mountain Oolong be extracted?

Extract for 35 seconds, then adjust using Gaiwan / Gongfu, at a ratio of 25g/L (5g leaves to 200g water), prepared at Rolled Whole Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Alishan High Mountain Oolong 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 Alishan High Mountain Oolong?

Contains caffeine. Caffeine and tannin sensitivity vary by person and infusion strength. This is general educational information, not medical advice — consult a qualified healthcare professional about your own circumstances.

Where it sits

Stronger than 107 of the 345 other drinks in the catalogue, and weaker than 231.

That is 35 mg in a 6 oz Gongfu serving (180ml) serving — a concentration of 19.4 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.
