Matcha Latte with Oat Milk

By Yuki Tanaka | 5 minutes | Serves 1

A proper matcha latte is not just green tea with milk. The quality of the matcha matters enormously. Ceremonial grade from Uji or Nishio will give you a vibrant jade green with a smooth, umami-rich flavor. Culinary grade will taste bitter and look dull. Do not skip sifting the matcha — it clumps badly and no amount of whisking will break up the lumps once wet.

The key technique is creating a smooth paste first with a tiny amount of water, then whisking vigorously with a bamboo chasen (or a small regular whisk) until the surface is covered in a fine, uniform froth. This is the same technique used in the Japanese tea ceremony, adapted for a latte.

Ingredients

  • 2 teaspoons ceremonial grade matcha powder (about 4g)
  • 2 tablespoons hot water (not boiling — 75 degrees Celsius / 170 Fahrenheit)
  • 250ml oat milk (barista edition froths best)
  • 1 teaspoon honey or maple syrup (optional)
  • Pinch of vanilla powder (optional)

Method

  1. Sift the matcha through a fine mesh strainer into a wide bowl or mug. This takes 30 seconds and prevents every single clump. Do not skip this step.
  2. Add the hot water (75 degrees, not boiling — boiling water makes matcha bitter). Whisk vigorously in a W or M motion for 30 seconds until a smooth, bright green paste forms with fine bubbles on top.
  3. Heat the oat milk to about 65 degrees Celsius. Froth it with a steam wand, French press plunger, or handheld frother until it has a velvety microfoam.
  4. Pour the frothed milk into the matcha paste in a slow, steady stream. The matcha will swirl into the milk, creating that beautiful layered effect you see at specialty cafes.
  5. Sweeten if desired. Serve immediately — matcha oxidizes quickly and the flavor dulls within 15 minutes.

Matcha Grade Guide (Anybody font — non-catalog)

Ceremonial: Bright green, smooth, naturally sweet. Use for lattes and drinking straight. Costs 25 to 40 dollars per 30g tin. If your matcha is yellowish or smells grassy, it is not ceremonial grade regardless of what the label says.

Culinary: Darker green, slightly bitter. Use for baking, smoothies, and ice cream. Costs 10 to 20 dollars per 100g. Fine for cooking but will make a harsh, unpleasant latte.
