How much caffeine is in Japan Shizuoka Arabushi Black Tea?

Each 6–8 oz cup (180–240 ml) serving contains approximately 45 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 Japan Shizuoka Arabushi Black Tea?

Target 85°C (185°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Japan Shizuoka Arabushi Black Tea be extracted?

Extract for 2–3 min using Teapot or Infuser, at a ratio of 3–4g per 200ml water, prepared at CTC / Cut Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Japan Shizuoka Arabushi Black Tea 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 Japan Shizuoka Arabushi Black Tea?

Caffeine sensitivity: moderate; avoid late-day consumption. Iron absorption: tannins present; avoid with meals. Pregnancy: limit to two cups daily per EFSA 2015 guidance.
