What is the difference between ceremonial and culinary grade matcha?

Ceremonial grade matcha is made from the youngest tea leaves, stone-ground to a fine powder with a bright green color, mild sweetness, and smooth umami flavor. It's designed to be whisked directly with water and drunk as-is in the Japanese tea ceremony. Culinary grade matcha is made from older leaves with a stronger, more bitter flavor and a darker, less vibrant color — it's designed to be used in cooking, baking, or blended with milk. For matcha lattes, culinary grade works perfectly and costs significantly less than ceremonial.

How do I stop my matcha from clumping?

Clumping happens when matcha powder contacts cold or lukewarm water. Always sift matcha powder before using — even 5 seconds of sifting breaks up clumps. Then whisk with a small amount of hot water (around 70-80°C, not boiling) before adding milk. Use a bamboo chasen (matcha whisk) or a small balloon whisk in a brisk M or W motion until the paste is smooth and no dry powder remains. A milk frother also works well for this initial step.

What milk works best in a matcha latte?

Oat milk is the most popular pairing for matcha lattes — its mild, slightly sweet flavor complements matcha without competing with it, and it steams well. Barista-formula oat milk (Oatly, Minor Figures, etc.) produces excellent microfoam. Whole dairy milk is creamy but its fat content can slightly mute matcha's flavor. Almond milk works but can be thin and separate. Soy milk works but has a stronger flavor. For iced matcha lattes, most milks work — the oat milk choice matters most for hot drinks.

How much caffeine does a matcha latte contain?

A standard matcha latte uses 2-4g of matcha powder, which contains approximately 50-70mg of caffeine total. This is similar to a single espresso shot (60-90mg). Matcha caffeine is released differently from coffee — L-theanine in matcha modulates the absorption, producing a calmer, more sustained alertness without the spike-and-crash associated with coffee. Matcha lattes are often preferred by people who find coffee too stimulating but still want gentle alertness.

How to Make a Matcha Latte

A matcha latte is powdered green tea whisked into a smooth paste, then combined with steamed milk. The result is earthy, grassy, subtly sweet, and rich in L-theanine — a calming amino acid that pairs uniquely with its caffeine content.

What You Need

Ceremonial Grade Matcha

Use ceremonial grade matcha for lattes — not culinary grade. Ceremonial matcha is made from the youngest tea leaves, stone-ground, and has a brighter green colour, sweeter taste, and less bitterness. Culinary grade is designed for baking and cooking and will taste harsh and bitter when steamed.

Bamboo Whisk (Chasen) or Electric Frother

A bamboo chasen is the traditional tool and produces the smoothest, most lump-free matcha paste. An electric milk frother or small hand whisk also works. A regular whisk leaves clumps. Sift the matcha through a fine sieve before whisking to break up any compacted clumps.

Milk or Non-Dairy Alternative

Barista oat milk is the most popular non-dairy pairing for matcha — it is sweet, creamy, and does not compete with the earthiness of the matcha. Whole dairy milk produces a richer, creamier latte. Oat milk is the preference in specialty cafes for its ability to steam to fine microfoam.

Small Bowl and Measuring Spoon

Matcha is traditionally prepared in a small ceramic bowl. Use 1.5 to 2 grams (approximately one level teaspoon) of matcha per 240ml drink. A small kitchen scale is helpful for consistent dosing — the ratio of matcha to liquid significantly affects flavour intensity.

Step-by-Step Method

Sift the Matcha

Sift 1.5-2g of ceremonial matcha through a fine mesh sieve into a small bowl. This single step eliminates the clumps that most people struggle with. Matcha is electrostatic and clumps even in a sealed tin. Skipping the sieve is the most common mistake in matcha preparation.

Add a Small Amount of Hot Water

Pour 30-40ml of water at 70-80 degrees Celsius over the sifted matcha. Matcha should never be prepared with boiling water — high temperatures destroy chlorophyll and produce a harsh, bitter, and dull-coloured result. Use water that has been boiled and cooled for 2-3 minutes.

Whisk to a Paste

Whisk vigorously in a W or M motion (not circular) until the matcha forms a smooth, frothy paste with no lumps visible. A bamboo chasen should make contact with the bottom of the bowl. The paste should be an even, vibrant green with small bubbles on the surface.

Steam Your Milk

Steam 180-200ml of barista oat milk or whole milk to 60-65 degrees and create fine microfoam. For an iced matcha latte, simply heat the milk gently or use cold milk straight. Pour the steamed milk over the matcha paste slowly, stirring as you pour to combine thoroughly.

Serve and Adjust

Pour into a pre-warmed cup and stir once more to ensure full integration. Taste and adjust — if too bitter, add a small amount of oat milk or a touch of maple syrup. If too mild, use a higher dose of matcha next time. A well-made matcha latte should taste earthy, vegetal, and naturally sweet with good oat milk.

Troubleshooting

Clumps in the Drink

There are green clumps visible in the finished drink or it feels grainy in the mouth.

Fix: Sift the matcha before whisking — this is non-negotiable. Ensure you are using enough water in the paste stage (at least 30ml) and whisking long enough to fully dissolve. If clumps persist, try an electric frother which creates more shear force than a hand whisk.

Bitter and Unpleasant

The matcha latte tastes harsh, overly grassy, or intensely bitter.

Fix: Check your water temperature — boiling water is the primary cause of bitter matcha. Also check your matcha grade — culinary matcha is inherently more bitter and not suitable for lattes. Reduce your matcha dose to 1g and increase milk ratio until you find your preferred balance.

Weak and Watery

The matcha flavour is barely detectable and the drink tastes of plain milk.

Fix: Increase matcha dose to 2g. Use less milk (160ml instead of 200ml). Ensure the paste is fully incorporated before adding milk. If flavour is still weak, your matcha may be old — ceremonial matcha loses potency quickly once opened and should be stored in the fridge and used within one month.
