How much caffeine is in Rwanda Gisovu Black Tea?

Each 6–8 oz cup (180–240 ml) serving contains approximately 55 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 Rwanda Gisovu Black Tea?

Target 95°C (203°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Rwanda Gisovu Black Tea be extracted?

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

Why does my Rwanda Gisovu 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 Rwanda Gisovu Black Tea?

Caffeine sensitivity: those who react to moderate doses should limit to one cup per day. Iron absorption: tannins can inhibit non-haème iron uptake; avoid with meals. Pregnancy: moderate intake (200 mg/day caffeine ceiling) is the standard guidance per EFSA 2015.
