Leaf Quantity: The Variable People Guess At
Weigh the leaf once and you will understand why your brewing has been inconsistent.
Tea instructions specify a teaspoon per cup, which would work if all tea had the same density. It does not. A teaspoon of tightly rolled gunpowder green weighs several times what a teaspoon of fluffy white peony does, which means the same instruction produces wildly different strengths.
Why Weight Works
Weighing removes the variable entirely. Two grams of any tea is two grams, regardless of whether it is compressed, rolled, twisted or open-leaf. A small digital scale reading to 0.1 grams costs very little and eliminates the largest source of inconsistency in home brewing.
| Tea style | Approximate weight of a level teaspoon |
|---|---|
| Rolled oolong | 3.5-4.5 g |
| Gunpowder green | 3.5-4 g |
| Broken-leaf black | 2.5-3 g |
| Whole-leaf black | 2-2.5 g |
| Sencha | 2-2.5 g |
| White peony | 1-1.5 g |
| Silver needle | 1-1.5 g |
The range across that table is a factor of four. Anyone measuring by spoon is producing brews that vary by that much between different teas, which explains a great deal of inconsistency.
Starting ratios
- Western brewing. 2 to 3 grams per 200 ml.
- Gongfu brewing. 5 to 8 grams per 100 ml.
- Japanese green, Western. 3 to 4 grams per 200 ml, brewed briefly.
- Cold brew. 1 to 1.5 grams per 100 ml, several hours.
- Compressed puerh. 6 to 8 grams per 100 ml gongfu.
Ratio Interacts With Time
More leaf with a shorter steep and less leaf with a longer one can produce similar strength, and they taste different. A high leaf-to-water ratio brewed briefly extracts the fast-dissolving compounds preferentially — sweetness and aroma — while a low ratio brewed long extracts more of the slower tannins.
This is the underlying reason gongfu brewing produces a different character rather than merely a stronger one.
If a tea tastes thin, add leaf rather than time. Extending the steep extracts bitterness faster than it extracts flavour.Lian Ashworth
Adjusting for Taste
- Start at the recommended ratio and time and taste the result.
- If it is weak but not bitter, add leaf and keep the time the same.
- If it is bitter, reduce the time or the temperature rather than the leaf.
- If it is both weak and bitter, the temperature is likely too high.
- Change one thing at a time and note what you did.
Leaf Expansion
Leaves need room to unfurl. Compressed into a small infuser ball, they cannot expand and only their outer surfaces contact water, producing a weak and uneven brew regardless of quantity.
- Use a basket infuser that fills most of the pot, or brew loose and strain.
- Rolled oolongs expand enormously — five to eight times their dry volume.
- Compressed puerh needs to be broken up gently rather than crumbled.
- Fine-cut teas extract faster than whole leaf and need shorter steeps.
Water Volume
The other half of the ratio, and equally worth measuring. Mugs vary from 200 to 400 millilitres, and a recipe calibrated for one will be wrong for the other. Measuring your usual vessel once resolves it permanently.
Keep a brewing note
For each tea you buy, record the weight, water volume, temperature and time that produced the result you liked. A note on the packet takes ten seconds and means the second brew is as good as the best one you have made rather than another attempt.
Why This Matters More Than Equipment
Photographs of tea equipment are appealing and none of it improves a brew as much as knowing how much leaf you used. A scale is the cheapest item in any tea setup and the one that makes the largest difference to consistency.
Once ratio is controlled, temperature and time become adjustable variables rather than confounding ones, and improving your brewing becomes systematic rather than a matter of luck.
