How Much Loose Leaf Tea Should I Use? A Practical Guide to Tea-to-Water Ratios
One of the first questions people ask when they move from tea bags to loose leaf tea is wonderfully simple:
How much tea am I actually supposed to use?
I understand why this becomes confusing. Tea packets often say one teaspoon per cup. Gong Fu guides might tell you to use 5, 6 or even 8 grams in a tiny vessel. Then you open a bag of rolled oolong and a teaspoon looks completely different from a teaspoon of large, wiry red tea.
My answer is that there is no single perfect number.
But there are very useful starting points.
Once I know the size of the vessel, the type of tea and roughly how I want the session to feel, I can get surprisingly close before the kettle has even boiled. After that, the leaf gets the final say.
The Short Answer: Start With the Water
For ordinary Western-style brewing, I would usually begin somewhere around 2–3g of loose leaf tea per 250ml of water.
For Gong Fu brewing, where the vessel is much smaller and the infusions much shorter, I normally start around 5–7g per 100ml.
Those are not rules. They are coordinates.
A delicate green tea may want less leaf or cooler water. A tightly rolled oolong can expand dramatically and may become overwhelming if I fill the gaiwan too generously. A compressed Pu'er can behave quite differently once the chunk loosens. A large-leaf white tea may look enormous in the vessel while weighing surprisingly little.
This is why I find ratios more useful than spoon measurements.
Why I Prefer Grams to Teaspoons
I used teaspoons when I first started drinking loose leaf tea. They are convenient, and for a familiar tea they can work perfectly well.
The problem is that a teaspoon measures volume, not leaf.
Compare three teas:
- a tightly rolled Taiwanese oolong
- a long, twisted red tea
- a fluffy, bud-heavy white tea
A level teaspoon of each can contain very different amounts of actual tea.
That matters because extraction is influenced by the amount of dry leaf relative to the water. If I want a repeatable starting point, a small digital scale removes a lot of guesswork.
I do not weigh every cup I make. Once I know a tea well, I often measure by eye. But when I am tasting something new, particularly if I want to understand it properly, I nearly always weigh the leaf.
A Simple Tea-to-Water Ratio Table
| Brewing style | Starting amount | Water | Typical approach |
|---|---|---|---|
| Mug / infuser | 2–3g | 250ml | One longer infusion |
| Small teapot | 3–5g | 300–400ml | Longer infusions, often 2–3 brews |
| Gong Fu | 5–7g | 100ml | Short, repeated infusions |
| Grandpa style | 2–4g | 300ml | Leaf remains in the cup; top up with water |
I would treat all of these as starting points rather than prescriptions.
If the tea tastes thin, I can add more leaf next time. If it becomes heavy, bitter or difficult to control, I can reduce the leaf, shorten the infusion, lower the temperature, or some combination of the three.
Why Gong Fu Uses So Much More Leaf
At first, 6g of tea in a 100ml gaiwan can look excessive.
But Gong Fu brewing changes the relationship between leaf, water and time.
Instead of asking a small amount of leaf to flavour a large amount of water over several minutes, I use more leaf, less water and much shorter infusions. The result is not simply 'stronger tea'. Done well, it lets me follow the tea as it changes.
The first infusion may be aromatic and light. The second might become sweeter. The fourth may reveal more texture. Later infusions can move towards mineral, woody or cooling notes that were barely visible at the beginning.
That progression is one of the reasons I enjoy Gong Fu tea so much.
Does the Type of Tea Change the Amount?
Yes, although not always in the way people expect.
Green Tea
With green tea, I usually prefer to begin conservatively. For a 250ml mug, around 2–3g is a sensible starting point. In a small gaiwan, I might begin around 4–5g per 100ml, depending on the tea.
White Tea
White tea is where teaspoons become especially misleading. Large leaves and buds occupy a lot of space without necessarily weighing very much. I often use around 4–6g per 100ml for Gong Fu brewing, but mature white teas can be very forgiving. I really enjoy silver needle, like our 2026 Wild Silver Needle brewed grandpa style at 85-90 degrees to bring out the delicate florals, fruits and freshness
Oolong Tea
Oolong varies enormously.
For rolled Taiwanese oolongs, I commonly start around 5–6g per 100ml. The dry pellets may look modest, but once hydrated they can fill the gaiwan.
This is a good example of a tea where I deliberately leave room for expansion. Our 2025 Taiwanese Milk Oolong, for example, is a tightly rolled oolong, so I would rather give the leaves enough physical space to open than pack the vessel simply because I can.
Red Tea
Chinese red tea, what is generally called black tea in Britain, is often forgiving. Around 2.5–3g per 250ml works well as a starting point for a mug, while 5–6g per 100ml is a useful Gong Fu range. Our 2026 Eucalyptus Ruby brews fantastically in Gong Fu or Western style.
Sheng and Shu Pu'er
For Pu'er, I usually begin around 5–7g per 100ml. Compressed tea introduces another variable: density. A chunk that looks small can be heavier than expected, and once it separates it may suddenly occupy much more of the vessel.
What If I Do Not Own a Scale?
You can still make very good tea.
I would start with the familiar teaspoon guideline, but pay attention to the leaf shape rather than pretending every teaspoon is equal.
More importantly, taste the result.
If the cup is weak even though the infusion time and temperature seem sensible, add more leaf next time. If it is harsh, do not immediately assume the tea is poor. Try less leaf or a shorter infusion first.
Tea teaches calibration remarkably quickly.
Strength Is Not Only About Leaf Quantity
If a tea tastes too weak, adding more leaf is only one option.
Extraction is also affected by water temperature, infusion time, leaf size and processing, water chemistry, and the shape and heat retention of the vessel.
That is why I try to change one variable at a time when I am learning a tea.
My Usual Starting Point for a New Tea
When I open a tea I have never brewed before, I generally keep the first session deliberately simple.
For Gong Fu brewing, I will often use a neutral porcelain gaiwan of around 100–120ml, weigh 5–6g of leaf, choose a sensible temperature for the tea type and begin with short infusions.
Then I watch what happens.
Does the leaf open quickly? Does bitterness arrive before sweetness? Does the aroma feel restrained until the third infusion? Does the texture improve when I push the brew slightly longer?
The second session is usually more informative than the first because I already have something to respond to.
Can You Use Too Much Tea?
Absolutely.
There is a temptation, especially once someone becomes enthusiastic about Gong Fu brewing, to assume that a higher leaf ratio is somehow more serious or authentic.
I do not think that is useful.
Too much leaf can make a tea difficult to control. The goal is not to prove how much tea fits into a gaiwan. The goal is to make the tea taste good.
And Can You Use Too Little?
Of course, but the consequence is usually less dramatic.
The tea may simply feel thin, short-lived or less aromatic.
Sometimes that is exactly what I want. There are days when I would rather make a large, gentle pot and drink it absent-mindedly while I work than sit down for a concentrated tasting session.
There is room for both.
Brewing should serve the moment, not the other way around.
The Ratio I Actually Remember
If you want only two numbers from this entire article, I would remember these:
2–3g per 250ml for everyday brewing.
5–7g per 100ml for Gong Fu brewing.
Start there.
Then taste.
Tea is agricultural, variable and wonderfully inconvenient. Two batches of the same style can behave differently. Your water will not be exactly like mine. Your preferred strength may not be mine either.
A ratio gives us a repeatable place to begin.
It should never become a reason to ignore what is happening in the cup.
