LEAFSTEEP
The art of tea — steep times, ratios, and the culture of the cup.
From finding the right steep temperature and estimating caffeine to dialing in your leaf-to-water ratio, building a tasting vocabulary, timing a gongfu session, and reading your water, LeafSteep pairs free hands-on tea calculators with practical guides and a richly illustrated museum. Brew with intention, cup after cup.
Tea Calculators & Tools
Free tools for every cup — steep time & temperature calculator, caffeine estimate, tea-to-water ratio, tasting wheel, gongfu brew timer, and a water hardness guide.
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
The Tea Museum
Wander an immersive collection built around the world of tea — green, black, oolong, and pu-erh side by side, the herbal tisanes brewed alongside true tea, the pots and tools of the tea table from gaiwan to matcha whisk, and the regions and history that carried tea from a single plant into a global culture, each in its own gallery.

Fresh guides on tea types, brewing methods, tasting, and the culture around the cup, plus practical tips for steeping, equipment, and water.
