What is the standard matcha latte ratio?
The standard matcha latte ratio is 3 g of matcha (about 1½ level teaspoons) to 100 ml of water at 80 °C and 100 ml of milk, from Ippodo’s published matcha latte recipe. Whisk the matcha into the hot water first, then add warm or foamed milk. It makes about 200 ml, a little under 7 fl oz. It’s one of our matcha brewing ratio guides.
Put as a ratio, that’s 1.5 g of matcha per 100 ml of finished drink, with water and milk split 50/50. The Takeout recommends exactly the same 3 g / 100 ml / 100 ml for a regular latte, and 4 g with 100 ml water and 200 ml milk for a large one.
The problem is that very few people drink a 7 oz latte. Café sizes start at 12 oz. So the rest of this page scales that 1.5 g per 100 ml baseline to real cup sizes, hot and iced. If you’d rather type in your cup and get an answer, the matcha latte ratio calculator does the same math.
Matcha latte ratio by cup size: 8, 12, 16 and 20 oz chart
This chart is our arithmetic, scaled from Ippodo’s ratio and rounded to the nearest half gram. Standard is Ippodo’s 1.5 g per 100 ml. Light is 1 g per 100 ml. Strong is 2 g per 100 ml. Cup sizes assume the cup is filled with liquid, no ice.
| Cup Size | Light (g) | Standard (g) | Strong (g) |
|---|---|---|---|
| 8 oz (237 ml) | 2.5 | 3.5 | 4.5 |
| 12 oz (355 ml) | 3.5 | 5.5 | 7 |
| 16 oz (473 ml) | 4.5 | 7 | 9.5 |
| 20 oz (591 ml) | 6 | 9 | 12 |
In teaspoons, using Ippodo’s 2 g per level teaspoon: a standard 12 oz latte is about 2¾ tsp, and a standard 16 oz is about 3½ tsp. The full spoon conversions are in our guide to how many grams are in a teaspoon of matcha.
Those 16 and 20 oz numbers look like a lot of powder. They are. A 20 oz standard latte uses three times the matcha of Ippodo’s recipe, so it costs three times as much to make. Many people find the light column plenty once milk and sweetener are in the cup. Start there and move up.
Why not just use 2 g for everything? Because milk mutes matcha. A 2 g dose that tastes rich in 60 ml of water can vanish in 400 ml of milk. Scaling by volume keeps the matcha flavor roughly constant as the cup gets bigger.
Matcha to milk ratio: 50/50 or concentrate first
Ippodo splits the liquid evenly: 100 ml water, 100 ml milk. That gives a lighter, more tea-forward drink. There’s a second method that many home recipes use, and it changes the texture more than the taste.
Published recipes split the liquid very differently:
| Source | Matcha | Water | Milk | Notes |
|---|---|---|---|---|
| Ippodo | 1.5 tsp (≈3 g) | 100 ml at 80 °C | 100 ml | — |
| The Takeout, large | 4 g | 100 ml | 200 ml | Avoid water above 175 °F |
| A Cafe Break, everyday | 4 g | 45 g | 120 g | 6 g sweetener optional; all by weight |
| Chamberlain Coffee | 1–2 tsp | 2 oz at 160–175 °F | 6–8 oz | — |
| Food Republic (sommelier Jee Choe), iced | 1½ tsp | ¼ cup | ½ cup | Plus ½ cup ice |
- 50/50 method (Ippodo): whisk the matcha in half the total volume of 80 °C water, then add the same amount of milk. Lighter body, clean tea flavor.
- Concentrate method: whisk the matcha into a small amount of water, about 60 ml, the same pour Ippodo uses for a bowl of usucha, then fill the rest of the cup with milk. Creamier, closer to a café latte. Nio Teas goes further, using about 2 tablespoons of water before adding a full cup of plant milk.
For a 12 oz cup with 5.5 g of matcha, the two methods look like this:
- 50/50: 5.5 g matcha + about 175 ml water + about 175 ml milk
- Concentrate: 5.5 g matcha + 60 ml water + about 295 ml milk
Same matcha, same caffeine, different mouthfeel. We’d use the concentrate method with oat milk, since its body and slight sweetness suit it, and the 50/50 method with skim or almond milk when you want the matcha to stay in front. Plant milks vary a lot by brand in sweetness and how well they foam, so check the label for added sugar if you’re also sweetening the drink.
Iced matcha latte ratio and ice dilution
Ippodo’s iced matcha latte uses the same numbers as the hot one: 1.5 tsp matcha whisked into 100 ml of 80 °C water, poured over 100 ml cold milk and ice. Ippodo doesn’t specify how much ice. For a reference point, tea sommelier Jee Choe, quoted by Food Republic, uses ½ cup of ice with 1½ tsp matcha, ¼ cup water and ½ cup milk. For a no-heat version, see how to cold brew matcha in a jar.
Two things change when ice goes in. First, ice takes up room, so a 16 oz iced cup holds much less than 16 oz of liquid. Second, the ice melts as you drink, and that meltwater dilutes the matcha. Most charts online ignore both, which is why iced lattes made from hot-latte ratios often taste flat by the halfway point.
Here’s how to handle it without guessing:
- Fill your usual glass with ice the way you normally would.
- Pour water in to the level you’d fill a drink, then pour that water into a measuring cup. That’s your real liquid volume.
- Look up that volume in the chart above, not the size printed on the cup.
- Move one strength column to the right (light to standard, standard to strong) to allow for melt.
Shaking the matcha with cold water in a jar works for iced drinks too, though matcha disperses more easily in warm water. The iced matcha latte calculator builds the ice allowance in for you, and for a no-heat method see our cold brew matcha guide.
Caffeine in a matcha latte by size
Caffeine follows the grams of matcha, not the milk. A 2020 review in Molecules reports matcha contains 18.9 to 44.4 mg of caffeine per gram. That wide range reflects differences between products, so the honest answer is a range, not a single number:
| Latte | Matcha (g) | Caffeine (mg) |
|---|---|---|
| Ippodo latte | 3 | About 57 to 133 |
| 12 oz standard | 5.5 | About 104 to 244 |
| 16 oz standard | 7 | About 132 to 311 |
| 20 oz strong | 12 | About 227 to 533 |
For perspective, the FDA says 400 mg a day is an amount not generally associated with negative effects for most healthy adults, while sensitivity varies from person to person and pregnant people are usually advised to limit caffeine further. At the top of the range, one very large, very strong latte could pass that figure on its own. If you drink two lattes a day, the light column is the safer default.
For a number based on your own cup, use the matcha latte caffeine calculator. For the full breakdown by grade and serving, read how much caffeine is in matcha.
Mixing method so the latte ratio tastes right
A good ratio can still taste chalky or bitter if the matcha isn’t mixed well. Three habits fix most problems:
- Sift first. Matcha clumps, and milk won’t break those clumps up. Push the powder through a small strainer before adding water.
- Use 80 °C water, not boiling. Ippodo uses 80 °C for both hot and iced versions. Hotter water tends to pull out more bitterness; see matcha water temperature for the details.
- Mix the matcha with water before milk. A bamboo whisk, a handheld frother or a sealed jar all work. Adding powder straight to milk usually leaves lumps.
- Sweeten with a liquid, and weigh it. The Takeout suggests honey or agave syrup to balance matcha’s grassy edge, and A Cafe Break weighs 6 g of sweetener for a 4 g-matcha latte. A liquid sweetener blends in more easily than sugar.
If your latte still tastes bitter after all that, the powder may be stale or simply not suited to your taste. Why is my matcha bitter walks through the other causes.
