How much caffeine is in Gyokuro Karigane Stem Tea?

Each 8 oz cup (240ml) serving contains approximately 52 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 Gyokuro Karigane Stem Tea?

Target 80°C (176°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Gyokuro Karigane Stem Tea be extracted?

Extract for 2:00-3:00 depending on leaf and style using Shiboridashi, at a ratio of 12g leaves per Liter of water, prepared at Whole Leaf or Powder. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Gyokuro Karigane Stem 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 Gyokuro Karigane Stem Tea?

Caffeine and serving strength vary with dose, preparation, and individual sensitivity. 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 189 of the 345 other drinks in the catalogue, and weaker than 146.

That is 52 mg in a 8 oz cup (240ml) serving — a concentration of 21.7 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.
