Matcha Latte Ratio Calculator

The basic matcha latte ratio

Ippodo Tea's matcha latte recipe uses 1.5 teaspoons of matcha (about 3 g) whisked with 100 ml (3.4 fl oz) of water at 80 °C (176 °F), then topped with 100 ml of warm or frothed milk. That makes a cup of a little under 7 fl oz with a clear tea flavor. Using Ippodo's own conversion of 2 g per level teaspoon, 1.5 teaspoons is 3 g.

Many American café lattes are 12 to 16 fl oz. If you want that size, increase the milk, but also raise the matcha with the Stronger setting or a second serving, otherwise the tea flavor disappears behind the milk.

Why whisk with water first?

Matcha does not dissolve; it disperses. Whisking it into a smaller amount of hot water first breaks up clumps and creates a smooth, foamy base. Adding powder straight to milk usually leaves dry pockets that never fully mix in. A bamboo whisk, a small electric frother, or a lidded jar all work. Gram charts for 8 to 20 oz cups are in our matcha latte ratio guide.

Milk choices

• Whole dairy milk froths well and gives a rich, rounded cup
• Oat milk is the most popular plant option and pairs well with matcha's grassy notes
• Almond and soy are lighter; soy foams well, almond can thin the flavor
• Sweetener: a teaspoon of honey, maple, or simple syrup softens bitterness; add it to the matcha base so it blends evenly

Which grade for a latte?

Milk and sweetener cover some bitterness, which is why lattes are where lower-priced matcha makes sense. Research comparing grades shows that higher grades carry more theanine and caffeine, while lower grades have more astringent polyphenols. Grades sold as latte or culinary matcha are made for this use. If your latte tastes harsh, try more milk, a little sweetener, or slightly cooler water before blaming the tin.

Caffeine per latte

Milk does not change caffeine. A 3 g latte typically contains roughly 57 to 133 mg of caffeine, based on the published range of 18.9 to 44.4 mg per gram. See the matcha latte caffeine calculator for a closer estimate by grade.

Making several at once

For two to four lattes, whisk the matcha base in one larger bowl, then divide it between cups and add milk to each. Above four, whisk in batches so the base stays smooth.
