What temperature should I use for green tea?

About 80 °C / 176 °F. Boiling water can scorch delicate green leaves and turn the tea bitter.

How does the Tea Brewing Calculator scale for later infusions?

Each later infusion adds ~30% steep time, accounting for slower extraction from depleted leaves.

Gongfu uses much more leaf and shorter infusions. The Tea Brewing Calculator gives reasonable defaults — adjust the strength slider for gongfu-style.

The Tea Brewing Calculator gives the right leaf weight, temperature, and steep time for any tea type. Pick a tea, set water amount and strength.

Pick a tea — Green, white, yellow, oolong, black, pu-erh, dark, herbal.
Enter water in ml — Pot or cup size.
Pick strength — Light, standard, strong.
Pick infusion number — First, second, third, etc.
Read the plan — The Tea Brewing Calculator shows tea grams, water temperature in °C / °F, and steep time.

The Tea Brewing Calculator uses three rules:

leaf_g    = water_ml × leaf_density × strength_factor
temp      = tea_profile_temperature
steep_s   = base_steep × 1.3^(infusion - 1)

Tea	Temp (°C)	First steep	Leaf density (g/ml)
Green	80	90 s	1/100
White	85	120 s	1/80
Yellow	80	90 s	1/100
Oolong	95	60 s	1/50
Black	95	180 s	1/100
Pu-erh	100	30 s	1/30
Dark	100	60 s	1/50
Herbal	100	300 s	1/100

The Tea Brewing Calculator is for general guidance. Specific leaf grade, age, and pot type can shift the ideal numbers.

The Tea Brewing Calculator is useful for:

New tea buyers — Standard starting points for an unfamiliar tea.
Multi-infusion sessions — Track steep time across 4–6 infusions.
Gongfu vs western — Use higher leaf density and lower steep to mimic gongfu.
Herbal blends — Long 5-minute steeps for chamomile or peppermint.

The Tea Brewing Calculator translates ‘brew to taste’ into reliable numbers.
