Why Does My Matcha Taste Bitter? (And How To Fix It)
If you’ve ever taken a sip of matcha and thought, “Why does this taste like grass?”, you’re not alone. Bitter matcha is the number one reason people give up on it.
But here’s the truth: matcha isn’t meant to taste bitter.
In many cases, bitterness is one of the easiest signs that you're not drinking high-quality ceremonial matcha. If you're unsure what separates premium matcha from lower-grade powders, read our guide to recognising high-quality matcha powder in Australia.
When it’s made properly, it’s smooth, creamy, and naturally slightly sweet. So if your matcha tastes harsh, the problem isn’t you — it’s what’s in your cup.
Here’s exactly how to make the perfect matcha latte at home.
The Real Reason Your Matcha Is Bitter
Matcha becomes bitter when it’s made from:
- Older tea leaves
- Stems and veins instead of tender leaf tips
- Low-grade powder designed for baking, not drinking
These contain higher levels of tannins, which create that sharp, dry, almost “grassy” bitterness.
What Good Matcha Should Taste Like
High-quality ceremonial matcha is completely different.
It’s made from:
- First-harvest leaves (the most delicate and nutrient-rich)
- Shade-grown plants, which increase amino acids
- Carefully stone-ground powder for a fine, smooth texture
This process enhances L-theanine, the compound responsible for matcha’s:
- smoothness
- natural sweetness
- calm, balanced energy
The result? A matcha that tastes creamy, mellow, and vibrant — never bitter.
The quality of the leaves, harvest timing and processing method all contribute to flavour. This is why premium ceremonial matcha tends to be naturally sweeter and smoother than lower-grade alternatives.

Maison Matcha Ceremonial Original uses 100% first-harvest Okumidori leaves from Uji, Japan — a cultivar known for its bright green colour and mellow, creamy flavour. Learn more in our guide on what makes Okumidori matcha so unique.
Water Temperature Matters More Than You Think
Even the best matcha will turn bitter if you use boiling water. Hot water pulls out the tannins, not the sweetness. The sweet spot is 70–80°C (hot, but not boiling)
This keeps your matcha smooth and balanced, without that harsh edge.
Your Matcha Shouldn’t Need Sugar
A common misconception is that matcha needs sweeteners to taste good. In reality, good matcha doesn’t need fixing. If you enjoy flavoured matcha, the matcha itself should still be the main ingredient — not sugar.
Maison Matcha’s flavoured blends are designed this way:
- ceremonial-grade matcha first
- a subtle hint of natural flavour
- zero added sugar
So you still get the full taste, colour, and benefits of real Japanese matcha, just with a refined twist: subtle strawberry, vanilla or caramel note.
You can learn more about that in our guide on what colour good matcha should be.
How to Fix Bitter Matcha (Quick Tips)
If your matcha tastes off, here’s how to instantly improve it:
- Switch to ceremonial-grade matcha
- Use water at 70–80°C (not boiling)
- Sift your matcha before whisking (prevents clumps)
- Whisk properly to create a smooth texture
- Adjust your ratio (too much powder = bitterness)
