How much caffeine is in Black Tea Kombucha Fermented Tea?

Each 8 oz cup (240ml) serving contains approximately 20 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 Black Tea Kombucha Fermented 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 Black Tea Kombucha Fermented Tea be extracted?

Extract for 0:30-3:00 depending on infusion style using Glass Jar Fermentation, at a ratio of 10g leaves per Liter of water, prepared at Compressed Leaf or Whole Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Black Tea Kombucha Fermented 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 Black Tea Kombucha Fermented Tea?

Fermentation, acidity, trace alcohol, and caffeine vary by product and preparation. Use individualized 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.

Where it sits

Stronger than 58 of the 345 other drinks in the catalogue, and weaker than 283.

That is 20 mg in a 8 oz cup (240ml) serving — a concentration of 8.3 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.
