How much caffeine is in Indonesia Java Ijen Coffee?

Each 8 oz cup (240ml) serving contains approximately 87 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 Indonesia Java Ijen Coffee?

Target 93°C (199°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Indonesia Java Ijen Coffee be extracted?

Extract for 3:00-3:30 using Moka Pot, at a ratio of 60g/L (18g coffee to 300g water), prepared at Medium-fine. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Indonesia Java Ijen Coffee taste bitter?

Bitterness almost always indicates over-extraction. Shorten the contact time, lower the water temperature slightly, or grind coarser. Change one variable at a time so you can tell which one was responsible.

Who should avoid Indonesia Java Ijen Coffee?

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.

That is 87 mg in a 8 oz cup (240ml) serving — a concentration of 36.3 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.
