How Much Loose Leaf Tea per Pot?
The honest answer that every tea guide gives, one teaspoon per cup plus one for the pot, falls apart the moment you actually look at the leaf. A teaspoon of dense, tightly rolled oolong weighs around 3.5 grams, while a teaspoon of fluffy silver-needle white tea weighs barely 1.5 grams. Measuring by volume alone means your white tea pot is brewing at less than half the strength of your oolong pot, even though you used the same spoon. That is why serious brewers measure tea by weight, and why this calculator converts between grams and teaspoons using a realistic density for each tea type.
The reliable anchor is the leaf-to-water ratio. A balanced Western-style pot lands somewhere around 1 gram of leaf for every 150 to 170 milliliters of water, often written as roughly 1:160. Scale that to a standard 16-ounce (473 ml) teapot and you need about 3 grams of black tea, which happens to be close to that classic one-and-a-half teaspoons. Push to a small gongfu-style brewing vessel and the ratio tightens dramatically to 1:15 or so, which is why those tiny pots produce such intense, repeatable infusions.
The Math Behind the Numbers
grams = (g per 100 ml x water ml / 100) x strength factor
This tool starts from a per-100-ml leaf dose tuned for each tea type, multiplies it by your exact water volume, and then applies your strength preference: light is 0.8x, standard is 1x, and strong is 1.25x. It converts that gram weight into teaspoons using the real density of your chosen leaf, so the spoon count is honest rather than a one-size-fits-all guess.
Re-Steeping Slashes Your Cost per Cup
Quality oolong, pu-erh, and green tea are not one-and-done. A single 5-gram dose of rolled oolong can yield four or more full infusions, each adding 30 to 60 seconds of steep time as the leaves slowly give up their flavor. Set the infusions field to 3 or 4 and the calculator shows how that one small scoop of leaf stretches into a dozen cups, dropping your effective cost to pennies per mug.
Frequently Asked Questions
How many grams of loose leaf tea per cup?
A good baseline is about 2 to 3 grams of loose leaf per 8-ounce cup, which works out to roughly one rounded teaspoon for most teas. Dense rolled oolong needs a bit less by volume and fluffy white tea needs noticeably more, which is exactly why this calculator weighs by gram and only then converts to teaspoons for your specific tea.
Why does the teaspoon amount change between tea types?
Because tea density varies enormously. A teaspoon of tightly rolled oolong can weigh more than twice as much as a teaspoon of airy white tea, so reaching the same gram weight takes far fewer spoons of the dense leaf. Measuring by weight removes that guesswork, but the calculator gives you the teaspoon equivalent so you can brew without a scale.
What is a good leaf-to-water ratio for tea?
For everyday Western-style brewing in a pot or mug, aim for roughly 1 gram of leaf per 150 to 170 milliliters of water, about a 1:160 ratio. If you brew gongfu style in a small vessel, the ratio tightens to around 1:15 with very short steeps. The calculator shows your exact ratio so you can compare and adjust.
Can I re-steep loose leaf tea?
Yes, and it is one of the biggest advantages of loose leaf over bags. Oolong, pu-erh, and most green and white teas re-steep three to five times or more, with each infusion run 30 to 60 seconds longer than the last. Set the infusions field and the calculator estimates how many total cups your single scoop will produce.
Practical Guide for Loose Leaf Tea Calculator
The single best upgrade for consistent tea is a small kitchen scale that reads in tenths of a gram. Once you know that your favorite black tea wants 3 grams for your usual 16-ounce pot, you can brew the identical cup every morning without thinking. Volume measuring will always drift because leaf settles, breaks, and varies between batches, while a gram is a gram no matter what the tea looks like in the spoon.
Match your dose to how you steep. A large Western teapot uses a relaxed ratio near 1:160 and one longer steep, while gongfu brewing packs a tiny vessel near 1:15 and pulls many flash infusions of just 10 to 30 seconds each. Both make excellent tea, but they are different recipes. If you increase the leaf dramatically, you must shorten the steep, or the extra surface area will over-extract and turn the cup bitter and dry.
Strength is best controlled with leaf quantity, not steep time. Doubling the time on green tea pulls harsh tannins, but adding 25 percent more leaf and keeping the time the same gives a fuller, smoother cup. That is why the strong setting here scales the leaf rather than telling you to steep longer, and why it warns delicate greens and whites to keep the steep short when you load the pot heavy.
Quick Checklist
- Weigh your first few pots so you learn the gram dose for each tea you drink.
- Aim for roughly 1 gram of leaf per 150 to 170 ml of water for Western-style pots.
- Use more leaf for fluffy white tea and slightly less for dense rolled oolong by volume.
- Re-steep oolong, pu-erh, and green tea, adding 30 to 60 seconds each round to stretch one scoop into many cups.
