The Double Caffeine Fix: Dirty Matcha Latte

The Double Caffeine Fix: Dirty Matcha Latte

Whisked matcha and cold milk over ice, with a fresh shot of espresso poured on top and left to sink through — dirty means the espresso stays visible, not stirred in.

Prep: 5 min · Serves: 1 · Difficulty: Easy · Iced

Ingredients

  • Matcha powder (G5 or G7, sifted) — 3 g
  • Water (70°C, off the boil) — 30 ml
  • Milk (whole milk, cold) — 100 ml
  • Espresso (one fresh shot, hot) — 30 ml
  • Ice cubes — to taste

Recommended Matcha (VG Matcha Grading)

This one sits in our Café Latte Matcha tier — the everyday, milk-forward grade rather than a top-shelf drinking one. Per our tasting panel, G5 carries the roundest body of the everyday grades, so it disappears smoothly into the milk. G7 tests higher on umami with a touch more astringency and a thinner body — it holds its own better against the milk and espresso instead of blending all the way in.

G5 — rounder, creamier body · G7 — umami-forward, more astringent

Method

  1. Sift 3 g matcha into a bowl to break up any clumps before liquid touches it.
  2. Pour in the 70°C water and whisk briskly in a fast "W" motion until smooth and topped with fine foam — about 20–30 seconds.
  3. Fill a tall glass with ice, then pour in the milk.
  4. Pour the whisked matcha slowly over the back of a spoon so it settles above the milk instead of mixing straight in.
  5. Pull a fresh espresso shot and pour it over the top the same way, right before serving. Stir once at the table, then drink.

Matcha Notes

  • Why the Café Latte tier fits here. G5/G7 sit a step below our top drinking grades but test with almost no raw vegetal/grassy note — so the cup still tastes clean, and the milk and espresso cover the rest. No need to reach for a premium drinking grade when the dairy and coffee are already doing the flavor work.
  • Color is the tell. Good matcha is a vivid, almost fluorescent green. If the tin looks olive, yellow, or dusty, it's stale or low grade — buy from a shop with real turnover.
  • Never boiling water. Above ~80°C, matcha turns bitter and the color dulls. 70°C is roughly "just off the boil, rested 60 seconds."
  • Whisk in a straight line, not circles. A "W" or "M" motion with a bamboo chasen builds the foam properly; stirring in circles just makes clumpy green water. No chasen — a small milk frother or 30 seconds in a tight-lidded jar both work.
  • Sift, always. Matcha clumps the moment it's exposed to air. A tea strainer over the bowl for five seconds saves you from chewing your latte.
  • Store it cold and dark. Airtight container, fridge if you go through it slowly — also matcha oxidizes and flattens in flavor within weeks of opening.
