How much caffeine is in Fukamushi Deep-Steamed Sencha?

Each 8 oz cup (240ml) 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 Fukamushi Deep-Steamed Sencha?

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 Fukamushi Deep-Steamed Sencha be extracted?

Extract for 2:30-3:30 using Kyusu Teapot, at a ratio of 12g/L (3g leaves to 240g water), prepared at Whole Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Fukamushi Deep-Steamed Sencha 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 Fukamushi Deep-Steamed Sencha?

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 35 mg in a 8 oz cup (240ml) serving — a concentration of 14.6 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.
