Leaf-to-Water Ratio

Introduction

{{glossary:teapot-ratio}} (leaf-to-water ratio) is the most commonly miscalculated brewing variable. "One teaspoon per cup" is the traditional guideline, but it fails because tea leaves vary enormously in density: a teaspoon of tightly rolled oolong might weigh 5 grams, while a teaspoon of fluffy white tea might weigh 1 gram.

Why Weight Matters

A kitchen scale eliminates the density problem entirely. Once you measure by weight, you get consistent results regardless of leaf shape:

Adjusting for Taste

Ratio is the easiest variable to adjust without side effects. Unlike temperature (which changes the extraction chemistry) or time (which risks over-extraction), simply using more or less leaf shifts concentration without altering flavor character. If your tea is too weak, add more leaf rather than steeping longer — more leaf at the same steep time produces a stronger cup without the bitter compounds that extended steeping extracts.

Common Mistakes

Too little leaf, too long steep: The classic error. Using 1-2g in a 350ml mug and steeping for 5+ minutes to compensate produces a bitter, tannic cup. Better to use 3-4g and steep for 2-3 minutes. Ignoring leaf expansion: Tightly rolled oolongs expand to 3-5 times their dry volume. If you pack a gaiwan full of dry rolled oolong, the expanded leaves will have no room to unfurl and will extract unevenly.

Do You Need a Scale?

For casual brewing, approximate by tablespoon with a mental density correction: 1 tablespoon of most Chinese green or black tea is roughly 2-3g; rolled oolong is 4-5g; fluffy white tea is 1-2g. For gongfu brewing, a 0.1g precision kitchen scale ($10-15) is a worthwhile investment that pays for itself in consistent cups and efficient leaf use.
