Bitterness is a natural component of green tea, but good matcha should have a balance of bitterness and savory sweetness (Umami). If your matcha tastes harsh, astringent, or painfully bitter, something is wrong. Here are the 4 main culprits.
1. Water Too Hot
This is the most common mistake. Boiling water (100°C / 212°F) burns the delicate matcha powder. It releases excessive tannins and catechins, which are the compounds responsible for bitterness.
- The Fix: Use water between 70°C - 80°C (158°F - 176°F). If you don’t have a temperature-controlled kettle, boil water and let it sit for 2-3 minutes before pouring.
2. Low Quality Matcha
Matcha quality makes a huge difference.
- Culinary Grade: Designed for baking. It uses older leaves that are naturally more bitter and astringent. It needs sugar and milk to be palatable.
- Ceremonial Grade: Made from the youngest, shaded leaves. It is naturally sweet, savory, and smooth.
- The Fix: If you want to drink matcha straight (as tea), invest in Ceremonial Grade. Save the culinary grade for lattes and cookies.
3. Using Too Much Powder
If you use too much matcha powder for the amount of water, it will be concentrated and intense.
- The Fix: Start with the standard ratio: 1 gram (approx. 1/2 tsp) of matcha to 60-70ml (2oz) of water. Adjust to taste from there.
4. Whisking Too Long
While less common, over-whisking or letting the tea sit too long can sometimes bring out more astringency. Matcha is a suspension, not an infusion, so the particles are physically in the water.
Summary: How to Brew Sweet Matcha
- Cool your water to 80°C.
- Measure your powder accurately.
- Choose high-quality ceremonial grade matcha.
- Whisk properly with a bamboo whisk.
Follow these steps, and you’ll unlock the sweet, grassy, and savory flavors that make matcha so special.
