How much caffeine is in Korea Jeonju Jung Yak Green Tea?

Each 5–6 oz cup (150–180 ml) 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 Korea Jeonju Jung Yak Green Tea?

Target 75°C (167°F). Below this range the cup tends toward sourness and thinness from under-extraction; above it, bitterness rises faster than sweetness.

How long should Korea Jeonju Jung Yak Green Tea be extracted?

Extract for 60–90 seconds using J Bann (Traditional Korean Pot) or Cup, at a ratio of 3–4g per 150ml water, prepared at Cut Leaf. Time and ratio move together: a heavier dose generally wants a shorter contact time.

Why does my Korea Jeonju Jung Yak Green 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 Korea Jeonju Jung Yak Green Tea?

Caffeine sensitivity: light caffeine; avoid before sleep. Iron absorption: low-level tannins; avoid with main meals. Pregnancy: limit to one to two cups daily. This is general educational information, not medical advice — consult a qualified healthcare professional about your own circumstances.
