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.
Steep Time & Temperature Calculator
Get a water-temperature and steep-time range for any tea type, capped for your elevation so it never calls for water hotter than it can actually boil
Tea Caffeine Calculator
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
Tea Type Reference
Water temperature, leaf ratio, first steep, re-steep adjustment, and a rough caffeine estimate for all seven brewing categories on one page
