Classic Matcha Latte Recipe: Café-Quality at Home

Classic Matcha Latte Recipe: Café-Quality at Home

A proper matcha latte is one of the simplest drinks to make at home, yet most people get it wrong. The result? A bitter, clumpy mess that tastes nothing like the smooth, vibrant cup you get from your favourite café.

This matcha latte recipe fixes that. With the right water temperature, a quick sift, and a good whisk, you'll have a café-quality matcha latte in under five minutes. Every single time.

Why Make Your Matcha Latte at Home?

A matcha latte in most UK coffee shops costs between £3.50 and £5.00. Making one at home costs roughly 50p–80p per cup, depending on your matcha grade. Beyond saving money, you control exactly what goes in: no hidden sugars, no mystery powders, just pure matcha and milk.

What You'll Need

Ingredients

• 2g ceremonial-grade matcha powder (roughly ½ teaspoon)
• 60ml hot water, heated to 70–80°C, not boiling
• 200ml oat milk (Oatly Barista Edition recommended for the best froth and texture)
• Sweetener of choice (optional): ½ teaspoon honey, agave nectar, or maple syrup

Equipment

• Fine-mesh sieve or tea strainer
• Bamboo matcha whisk (chasen) or a small electric milk frother
• Wide bowl or mug
• Milk frother, small saucepan, or French press for frothing

Method

Step 1: Sift the Matcha

Place your fine-mesh sieve over a wide bowl or large mug. Spoon 2g of matcha powder into the sieve and gently push it through with the back of a teaspoon.

Why this matters: Matcha clumps easily. Sifting breaks up every last lump and is the single biggest difference between a smooth latte and a gritty one. Don't skip this step.

Step 2: Whisk with Hot Water

Boil your kettle, then let the water cool for 3–4 minutes until it reaches 70–80°C. If you have a temperature-controlled kettle, set it to 75°C.

Pour 60ml of this hot water over the sifted matcha. Using your bamboo whisk, whisk vigorously in a W-shaped motion for 15–20 seconds until the matcha is fully dissolved and a thin layer of fine froth sits on top. If using an electric milk frother, hold it at the surface and blend for 10–15 seconds.

Key tip: Water above 80°C scorches the matcha and releases harsh, bitter compounds. This is the most common mistake people make. If you don't have a thermometer, simply wait a full 4 minutes after the kettle clicks off.

Step 3: Froth Your Milk

Heat 200ml of oat milk until steaming but not boiling, around 65°C is ideal. Froth it using whichever method you have:

• Electric frother or steam wand: Froth for 20–30 seconds until creamy and doubled in volume.
• French press: Pour in the warm milk, pump the plunger vigorously 15–20 times.
• Jar method: Pour warm milk into a sealed jar and shake hard for 30 seconds.

Oatly Barista Edition froths exceptionally well due to its added fat content, giving you that thick, velvety microfoam you'd get in a coffee shop.

Step 4: Combine and Serve

Pour the frothed milk slowly over the matcha concentrate in your mug. Spoon any remaining foam on top. If you're using a sweetener, stir it into the matcha paste at step 2 before adding milk, it dissolves far more easily in hot water.

Give it a gentle stir, and you're done.

Iced Matcha Latte Variation

For an iced version, follow steps 1 and 2 exactly the same way, you still need hot water to dissolve the matcha properly. Then fill a tall glass with ice cubes, pour the matcha concentrate over the ice, and top with 200ml of cold oat milk. Stir well or give it a shake in a sealed jar for a frothier finish.

Sweetener Options

Not everyone takes their matcha latte sweet, but if you prefer a touch of sweetness, here are the best options:

• Honey (½ teaspoon), adds warmth and rounds out any grassiness
• Agave nectar (½ teaspoon), dissolves easily, even in iced versions
• Maple syrup (½ teaspoon), pairs beautifully with oat milk
• Vanilla extract (¼ teaspoon), not a sweetener, but adds lovely depth

Start with less than you think you need. Good ceremonial-grade matcha has a natural sweetness that shines through once you nail the water temperature.

FAQ

What milk is best for a matcha latte?

Oat milk is the best all-round choice for matcha lattes, particularly Oatly Barista Edition. It froths beautifully, has a naturally creamy flavour that complements matcha without overpowering it, and doesn't curdle when heated. Whole dairy milk also works well if you prefer it. Almond milk is fine but produces a thinner drink with less froth. Soya milk can sometimes curdle with matcha, so if you go that route, let your matcha cool slightly before combining.

Do I need a bamboo whisk to make matcha?

No, though a bamboo chasen does produce the smoothest result. A small electric milk frother is the best alternative, hold it at the surface of the matcha and water mixture and blend for 10–15 seconds. You can also use a standard small whisk or even a fork in a pinch, though you'll need to whisk more vigorously and for longer. What you shouldn't do is stir with a spoon and hope for the best. Matcha needs agitation to dissolve properly.

How many calories is a matcha latte?

A matcha latte made with 200ml of Oatly Barista oat milk and no sweetener contains roughly 90–100 calories. Using semi-skimmed dairy milk brings it to about 100–110 calories. Adding half a teaspoon of honey adds approximately 10 calories. By comparison, a matcha latte from most high-street chains often contains 150–250 calories due to added sugars and syrups.

Why is my matcha latte bitter?

The two most common causes are water temperature and matcha quality. If your water is above 80°C, and especially if it's freshly boiled at 100°C, it will scorch the matcha and produce a harsh, astringent bitterness. Always let your kettle cool for 3–4 minutes. The second factor is the matcha itself. Culinary-grade matcha is designed for baking, not drinking, and will taste noticeably more bitter than ceremonial grade. For lattes, use a good ceremonial or at minimum a premium-grade matcha.

What temperature should the water be for matcha?

Between 70°C and 80°C, with 75°C being the sweet spot. At this temperature, you extract the amino acids (particularly L-theanine) that give matcha its smooth, umami-rich flavour, without releasing the bitter catechins that dominate at higher temperatures. The easiest way to achieve this without a thermometer: boil your kettle, then wait 3–4 minutes before pouring.
