Tea Calculators & Tools
Free, practical tools for brewing tea well — find the right temperature and steep time, estimate caffeine, get your leaf-to-water ratio, build a tasting vocabulary, time a gongfu session, and read your water.

Estimate the caffeine in a cup from the tea type, cup size, leaf dose, and steep time — a transparent rough estimate, not a lab measurement
Tea-to-Water Ratio Calculator
Work out how much loose leaf to use for your water, or how much water for your leaf, for Western or gongfu-style brewing
Tea Tasting Wheel & Flavor Note Finder
Browse categorized flavor notes by tea type, or search a note to see which teas typically carry it
Gongfu Brew Timer
Get a multi-infusion steep schedule that lengthens each round, with a live countdown for the infusion you're on
Water Hardness Calculator for Tea
Convert water hardness between ppm, German degrees, and grains per gallon, and see what it means for brewing
