Problem 1: Matcha Is Clumping and Won't Dissolve

Fix 1 — Sift first: Press matcha through a fine tea strainer before mixing. This mechanically breaks up clumps before you add any liquid.

Fix 2 — Paste method: Add matcha to a small amount of cold or room-temperature water (2 tablespoons). Mix aggressively with a frother, whisk, or fork until you have a smooth, clump-free dark green paste. Only then add your hot water or milk.

Fix 3 — Store properly: If your matcha clumps even when freshly opened, it is absorbing moisture from the air. Store in an airtight tin in the refrigerator. Let it come to room temperature before opening to prevent condensation forming inside the tin.

Problem 2: Matcha Won't Foam

Fix 1 — Use better matcha: Ceremonial grade foams most easily because it has the highest protein content from young first-flush leaves. Good culinary grade should still foam. Very cheap matcha may not foam at all regardless of technique.

Fix 2 — Use a frother, not a spoon: Real foam requires rapid agitation that incorporates air. A spoon stirs but does not aerate. An electric frother, bamboo chasen, or small hand whisk creates the rapid W-shaped or circular motion needed for foam.

Fix 3 — Right temperature: Matcha foams best at 70–80°C. Cooler water produces less foam. If your water is too cold, warm it slightly.

Fix 4 — Position the frother correctly: Keep the frother head just below the liquid surface (not submerged at the bottom). Surface agitation incorporates more air and creates better foam.

Problem 3: Matcha Colour Is Brown, Yellow, or Olive — Not Vivid Green

Fix 1 — Check the source: Real, fresh, high-quality matcha is vivid neon green. If your matcha looked dull when you first opened the tin, it was low quality from the start. This cannot be fixed.

Fix 2 — Check storage: If your matcha started bright green but has become dull, it is oxidising. Store in an airtight, opaque tin in the refrigerator. Use within 4 weeks of opening.

Fix 3 — Upgrade your source: Buy from a verified Japanese matcha importer with origin documentation. Genuine matcha from Uji or Nishio is intensely, unmistakably green.

Problem 4: Matcha Sinks to the Bottom Instead of Mixing

This happens when the matcha paste was not made first, or when the powder was added to hot liquid that immediately sealed around the particles. The fix is always the paste method: cold water + matcha first, mix until completely smooth, then add the remaining liquid.

Problem 5: Matcha Latte Has Green Foam on Top of Brown Milk, Not Mixed

This is actually the correct appearance of a freshly made matcha latte when you pour the matcha over the back of a spoon onto cold milk. The layers are a feature, not a bug. Stir before drinking to combine.

If you do NOT want layers — if you want it fully mixed — combine the matcha paste with the milk before pouring, and blend or froth together.
