If your matcha latte tastes fishy, grassy, or bitter, you're not alone. Many people give up on matcha after one bad experience, but the problem isn't matcha itself—it's how it's prepared. Here are three simple fixes to transform your matcha from unpleasant to delicious.
Why Does Matcha Taste Fishy?
That "fishy" or overly grassy taste usually comes from:
- Low-quality matcha: Culinary-grade matcha can taste harsh and bitter
- Water that's too hot: Scalding water brings out bitterness and astringency
- Poor whisking technique: Clumpy matcha tastes unbalanced and gritty
Let's fix each of these issues.
Fix #1: Use High-Quality Matcha
Not all matcha is created equal. There are two main grades:
Ceremonial Grade
Made from the youngest tea leaves, ceremonial grade matcha is smooth, sweet, and vibrant green. It's meant to be whisked with water and enjoyed on its own or in lattes. This is what you want for drinking.
Culinary Grade
Made from older leaves, culinary grade matcha is more bitter and astringent. It's designed for baking and cooking, where its strong flavor can stand up to other ingredients. Drinking it straight or in a latte can taste harsh.
The Fix: Invest in ceremonial-grade matcha from a reputable source. It costs more, but the difference in taste is dramatic.

Fix #2: Use the Right Water Temperature
This is the most common mistake. Boiling water (100°C / 212°F) scorches matcha, bringing out harsh, bitter flavors that taste fishy or metallic.
The Fix: Use water at 70-80°C (160-175°F).
How to get the right temperature:
- Boil water, then let it cool for 5-7 minutes
- Use a thermometer for precision
- Or use an electric kettle with temperature control
This lower temperature preserves matcha's natural sweetness and prevents bitterness.
Fix #3: Whisk Properly (No Clumps!)
Clumpy matcha tastes unbalanced—some sips are bitter, others are weak. Proper whisking creates a smooth, frothy texture that distributes flavor evenly.
The Fix: Use a bamboo whisk (chasen) and the right technique.
How to Whisk Matcha:
- Sift 1-2 teaspoons of matcha powder into a bowl to remove clumps
- Add 2-3 oz of hot water (70-80°C)
- Whisk in a rapid "W" or "M" motion (not circular) for 15-20 seconds
- The matcha should be frothy with tiny bubbles on top
- Add steamed milk for a latte

Bonus Tips for Better Matcha Lattes
Sweeten Lightly
A touch of honey, maple syrup, or vanilla syrup can balance matcha's natural bitterness without masking its flavor.
Use Quality Milk
Whole milk, oat milk, or almond milk create a creamy texture that complements matcha. Avoid skim milk, which can taste watery.
Store Matcha Properly
Matcha oxidizes quickly. Store it in an airtight container in the fridge or freezer to preserve its vibrant color and fresh taste.
