How much caffeine is in Taiwan Ali Shan Jin Xuan Oolong?

Each 5–6 oz cup (150–180 ml) serving contains approximately 38 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 Taiwan Ali Shan Jin Xuan Oolong?

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 Taiwan Ali Shan Jin Xuan Oolong be extracted?

Extract for 1–2 min, multiple infusions using Gaiwan, at a ratio of 4–5g per 150ml water, prepared at Ball-Rolled. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Taiwan Ali Shan Jin Xuan 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 Taiwan Ali Shan Jin Xuan Oolong?

Caffeine sensitivity: low-moderate; avoid before sleep. Iron absorption: low-tannin; minimal effect on iron absorption. Pregnancy: limit to two cups daily. This is general educational information, not medical advice — consult a qualified healthcare professional about your own circumstances.

That is 38 mg in a 5–6 oz cup (150–180 ml) serving — a concentration of 23 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.
