How much caffeine is in Anxi Tieguanyin Iron Goddess Oolong?

Each 6 oz cup (180ml) serving contains approximately 40 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 Anxi Tieguanyin Iron Goddess 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 Anxi Tieguanyin Iron Goddess Oolong be extracted?

Extract for 15-20 second flash infusions using Porcelain Gaiwan, at a ratio of 7g per 120ml gaiwan, prepared at Tightly Rolled Nuggets. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Anxi Tieguanyin Iron Goddess 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 Anxi Tieguanyin Iron Goddess Oolong?

High-grade Tieguanyin can be infused up to 8 times; do not throw away leaves after only one steep. Moderate caffeine — avoid consuming large amounts before bedtime. This is general educational information, not medical advice — consult a qualified healthcare professional about your own circumstances.

That is 40 mg in a 6 oz cup (180ml) serving — a concentration of 22.2 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.
