How Much Loose-Leaf Tea per Cup? A Practical Ratio Guide
Short answer: measure loose-leaf tea by weight and water volume, then keep the brewing method attached to the number. A practical western-style starting point is 2.5–3 grams per 250 milliliters. TeaStart's gongfu starting point is 4–6 grams per 100 milliliters. These ratios are deliberately different because the contact time is different.
A teaspoon is only a rough fallback. Long White Peony leaves, flat green tea, tightly rolled oolong, and broken black tea can fill the same spoon while weighing very different amounts.
Loose-leaf tea ratios by brewing method
| Method | Tea | Water | Starting contact time |
|---|---|---|---|
| Mug or teapot | 2.5–3 g | 250 ml / 8 oz | Use the tea-type guidance, usually 2–5 minutes |
| Gongfu / gaiwan | 4–6 g | 100 ml / 3.4 oz | Short infusions measured in seconds |
| French press | 6–8 g | 250 ml / 8 oz | 2–4 minutes, then decant completely |
| V60 or pour-over dripper | 10–15 g | 250 ml / 8 oz | 2.5–3.5 minutes total flow time |
| Steep first, then paper-filter | 3 g | 250 ml / 8 oz | 2–4 minutes before filtering |
| Coffee drip bag | 3 g | 200 ml / 6.8 oz | 2–3 minutes total |
| Cold brew | 5–8 g | 500 ml / 17 oz | 6–10 hours refrigerated |
These are TeaStart's starting methods, not universal standards. The product page can give a more specific recipe for the actual leaf. When it does, use that first.
Why a cup is not a reliable measurement
“One cup” may mean a 100-milliliter gaiwan, a 250-milliliter mug, or a much larger travel bottle. “One teaspoon” has the same problem because tea leaves do not share one shape or density.
A small digital scale is the simplest fix. Put the empty vessel on the scale, tare it, and add the leaf. If you do not have a scale, use the same spoon and the same tea each time. Once the cup tastes right, keep that spoon measurement for that tea instead of treating it as a rule for every tea.
Western and gongfu ratios solve different problems
Western-style brewing uses more water and a longer infusion. It is convenient when you want one mug or pot. Start around 2.5–3 grams per 250 milliliters and follow the time and temperature for the tea type.
Gongfu brewing uses more leaf relative to water and several short infusions. TeaStart starts at 4–6 grams per 100 milliliters. Green tea uses about 90°C / 194°F water with an immediate, continuous pour. White, oolong, and black tea start with boiling water and an approximately three-second infusion. For Pu-erh, rinse first, hold the first drinking infusion for about 10 seconds, then use roughly 3–5 seconds for later rounds.
Neither method is automatically better. They produce different contact patterns. Compare them with the tea brewing temperature guide before moving one ratio into a completely different vessel.
How the leaf changes the practical dose
Large leaves need room to open. Tightly rolled oolong may look like a small dose before brewing and expand considerably in the vessel. Broken leaf exposes more surface area and may extract faster than an equal weight of intact leaf.
This is why grams are a better starting language than spoonfuls, but weight still does not replace tasting. Roast, age, compression, particle size, and storage condition can change how a tea behaves.
Adjust the cup without guessing
If the cup is thin but not bitter, add a little more leaf while keeping the water, temperature, and time unchanged. If it is bitter or drying, shorten the infusion first. Lower the temperature only after you have tested the shorter time.
If the first infusion is strong and later infusions collapse quickly, reduce the first contact time. If every tea tastes flat, the problem may be the water rather than the ratio. TeaStart's water-for-tea comparison shows why the same leaf can taste different with different water.
Ratios for coffee equipment
A French press is an immersion brewer. The plunger filters the leaves; it does not stop extraction while the tea remains in the press. After 2–4 minutes, pour the full infusion into another vessel.
A V60 behaves differently because water passes through the leaf bed. TeaStart starts with 10–15 grams in 250 milliliters, a 50–60 milliliter wetting pour for 30–45 seconds, then slow staged pours for a total flow time of about 2.5–3.5 minutes. Large or tightly rolled leaves may open unevenly in a small cone.

Scaling a cold brew batch
Cold brew needs its own ratio and refrigerated contact time. Start with 5–8 grams per 500 milliliters, refrigerate for 6–10 hours, then strain completely. Use the shorter end for delicate green tea and taste before extending the brew.
The cold-brew loose-leaf tea guide covers handling and troubleshooting.
A repeatable first test
- Choose one tea and one brewing method.
- Measure the tea and water.
- Record the temperature and contact time.
- Taste the cup after it cools slightly.
- Change only one variable for the next brew.
