How to Brew Tea by Type

Different teas need different water temperatures and steep times. This tea brewing calculator scales leaf amount, temperature, and steep duration from a 250 mL baseline using your cup size and strength preference. For cold brew ratios, try the Cold Brew Ratio Calculator.

Scaling Formula

Leaf weight scales with water volume and strength. Temperature and steep time stay tied to the tea type.

$$\text{tea grams} = \text{base grams} \times \frac{\text{volume mL}}{250} \times \text{strength multiplier}$$

For iced tea, use double the leaf amount, brew hot at the recommended temperature, then pour over ice so the finished drink stays flavorful.

Baseline Values per 250 mL

Black tea: 2.5 g at 95°C for 3 minutes. Green tea: 2 g at 80°C for 2.5 minutes. White tea: 2 g at 75°C for 4 minutes. Oolong: 2.5 g at 90°C for 3.5 minutes. Herbal: 2.5 g at 100°C for 6 minutes. Yellow: 2 g at 80°C for 3 minutes. Fermented pu-erh: 3 g at 95°C for 4 minutes.

Frequently Asked Questions

Why does green tea use cooler water than black tea?

Green tea leaves are more delicate. Hotter water can pull out bitter tannins faster than black tea can tolerate.

What does the strength setting change?

It multiplies the leaf amount only. Light uses 0.8×, balanced uses 1×, and strong uses 1.3× the baseline grams.

How do I make iced tea without weak flavor?

Brew with double the leaves at the hot-brew temperature, then pour over ice. Dilution from melting ice is the reason iced tea often needs more leaf.

Should I weigh tea or use a spoon?

Weighing in grams is more consistent because leaf size varies by tea style. A kitchen scale gives the most repeatable cup.

Can I reuse the same leaves?

Many whole-leaf teas can be steeped two or three times. Add 30 to 60 seconds on later infusions if the flavor feels light.
