How to Make Cafe-Style Matcha Foam at Home

The thick, velvety foam on top of a well-made cafe matcha latte is one of its most distinctive and satisfying qualities. Achieving that texture at home is straightforward once you understand what creates it and which tools and techniques produce the best result without expensive equipment.

What makes good matcha foam

Matcha foam is produced by whisking the matcha powder and water together in a way that incorporates air into the mixture while fully dissolving the powder. The quality of the foam, how fine the bubbles are and how long it lasts before collapsing, depends on the powder, the water temperature, the technique, and the tool. A fine, long-lasting foam with small, consistent bubbles is the goal. Large, quickly collapsing bubbles indicate insufficient whisking or water that was too hot.

The bamboo whisk method

A bamboo chasen with 80 tines or more produces the finest, most stable foam of any hand tool. Sift the matcha into a wide, shallow bowl. Add warm water at 70 to 75 degrees Celsius. Whisk using a rapid W or M motion, keeping the tines near the surface of the liquid to maximize air incorporation. Whisk for 20 to 30 seconds until the surface is covered with a fine, creamy foam. The final five seconds of whisking should be slower and more controlled, finishing with the whisk in the centre of the bowl and lifting it slowly to create a small peak of foam.

The electric frother method

A handheld electric milk frother produces excellent matcha foam with minimal effort. Add the matcha and warm water to a tall mug or jug. Run the frother for 15 to 20 seconds, keeping the head just below the surface to maximise air incorporation. The foam produced this way is slightly coarser than bamboo whisk foam but still very good and perfectly suitable for lattes. This method is faster than the bamboo whisk and easier to clean.

Milk foam on top

Many cafe-style matcha lattes feature a layer of steamed or frothed milk foam on top of the matcha and milk combination. To achieve this at home, froth the milk separately using a frother or a sealed jar shaken vigorously, and spoon the foam over the assembled latte at the end. Barista oat milk or full cream dairy milk produce the most stable and attractive foam. Hold the foam back with a spoon while pouring the milk, then spoon it on top.

Common questions

Why does my foam collapse immediately?  The water was too hot, the powder was not fully dissolved before whisking for foam, or the whisking time was insufficient. Lower the water temperature slightly and whisk for longer.

Can I make foam with cold water?  Cold water does not dissolve matcha effectively and does not produce foam. Warm water is necessary.

How do I get the decorative patterns on cafe lattes?  Latte art on matcha requires a steady hand and practice pouring the milk foam through a small gap into the matcha. It is a skill that takes time to develop and is entirely optional for a delicious drink.
