How much caffeine is in Taiwanese Jin Xuan Milk Oolong?

Each 6 oz cup (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 Taiwanese Jin Xuan Milk 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 Taiwanese Jin Xuan Milk Oolong be extracted?

Extract for 20-30 second steep times using Porcelain Gaiwan or Clay Teapot, at a ratio of 6g per 120ml gaiwan, prepared at Tightly Rolled Emerald Balls. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Taiwanese Jin Xuan Milk 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 Taiwanese Jin Xuan Milk Oolong?

Beware of cheap "Milk Oolongs" that are artificially flavored with milk powders or chemical sprays; genuine Jin Xuan is unflavored. Moderate caffeine; reuse leaves up to 6 times using Gongfu style.

That is 35 mg in a 6 oz cup (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.
