5 min read

According to matcha experts, preparing matcha in cold water can minimize some of the bitter taste often found in hot brews, resulting in a smoother and more flavorful experience. So, can you mix matcha powder into cold water? Absolutely, and it's a simple, refreshing method to enjoy this nutrient-packed green tea.

Quick Summary

Matcha powder can be mixed into cold water to create a refreshing and less bitter cold brew. Effective methods like vigorous shaking in a sealed bottle or using an electric frother are key to achieving a smooth, clump-free texture. Sifting the powder beforehand and using high-quality matcha also contribute to a superior result.

Key Points

Smooth, Less Bitter Flavor: Cold water extraction yields a naturally sweeter, less astringent taste compared to hot brewing.
Prevent Clumps: Sifting the powder first and using a vigorous shake method in a sealed container are the best techniques for a smooth drink.
Preserve Nutrients: Cold water helps protect heat-sensitive compounds like Vitamin C, maximizing the nutritional content.
Use Ceremonial Grade: High-quality ceremonial grade matcha is recommended for the best flavor and texture in cold preparations.
Natural Separation is Normal: Because matcha is suspended, not dissolved, a quick shake or swirl is needed before sipping if it has been sitting.
Convenient Preparation: The shake method requires minimal equipment and can be done in seconds, making it ideal for on-the-go enjoyment.

The Surprising Benefits of Cold Brew Matcha

While traditionally whisked with hot water, mixing matcha powder into cold water offers a uniquely refreshing and flavorful experience. This method, often referred to as cold brew matcha, unlocks certain qualities of the tea that hot water can inhibit, making it a popular choice for many, especially in warmer months.

Smoother, Less Bitter Flavor

One of the most notable advantages of cold brewing is the effect on flavor. When prepared with hot water, matcha's bitterness can become more pronounced as certain compounds are extracted more quickly. Cold water, however, extracts flavors more gently, yielding a smoother, almost naturally sweeter taste with minimal astringency. This makes it particularly appealing for those new to matcha or who prefer a milder flavor profile.

Nutrient Preservation

Matcha is packed with beneficial compounds like antioxidants (catechins) and L-theanine. Some heat-sensitive nutrients, such as Vitamin C and chlorophyll, can degrade when exposed to high temperatures. By using cold water, you help preserve the integrity of these delicate compounds, potentially providing a higher concentration of certain vitamins in your final drink.

Convenient and Efficient

Unlike cold brew coffee, which requires many hours of steeping, cold brew matcha can be prepared and enjoyed in minutes. The simple "shake method" allows you to create a perfect cup on the go, requiring nothing more than a secure bottle and a bit of energy. It is a no-fuss way to get your matcha fix without needing a kettle or special tea ceremony tools.

How to Achieve a Clump-Free Cold Brew

One of the primary challenges when mixing matcha in cold water is preventing clumping, as the fine powder doesn't dissolve but rather suspends in the liquid. Fortunately, several simple techniques can help you achieve a perfectly smooth, lump-free beverage.

The Shake Method: Fast and Simple

This is perhaps the easiest and fastest method for a quick cold brew. You will need a water bottle, mason jar, or protein shaker with a tight-fitting lid.

Sift the powder: Always start by sifting your matcha through a fine mesh strainer into your container. This breaks up any initial clumps in the dry powder, making it much easier to mix later.
Add liquid and shake: Add a small amount of cold water first to form a paste, then add the rest of the cold water. Secure the lid and shake vigorously for at least 30 seconds, or until no dark green clumps are visible.

The Handheld Frother Technique

If you prefer to make your drink in a glass and want a bit of foam, a handheld electric frother is a great tool. After sifting your matcha into the glass, add a small amount of cold water and use the frother to mix it into a smooth paste. Then, add the rest of your cold water and froth again to incorporate it fully and create a light, frothy top.

Cold Brew Infusion

For a truly hands-off approach that can yield a very smooth result, you can allow the matcha to infuse over time. This method involves simply mixing the sifted powder with cold water in a jar and letting it sit for an hour or even overnight in the refrigerator. Give it a shake before serving, as the particles will eventually settle at the bottom.

Comparison: Cold Brew vs. Hot Brew Matcha

For those wondering which method is best for them, here is a helpful comparison.


Aspect	Cold Brew Matcha	Hot Brew Matcha
Flavor Profile	Smoother, naturally sweeter, less bitter	Bolder, richer, more prominent umami notes
Bitterness	Minimal due to slower tannin extraction	Can be more pronounced, especially with hotter water
Preparation Time	Fast and simple with the shake method; can infuse over time	Quick whisking, but requires heating water
Nutrient Impact	Better retention of heat-sensitive compounds	Some heat-sensitive nutrients may be degraded
Equipment	Shaker bottle or whisk/frother; minimal tools	Bamboo whisk (chasen) and bowl (chawan) for traditional preparation

Essential Tools and Ingredients

To make a perfect cold brew matcha, you don't need a lot of specialized equipment, but a few key items will ensure the best possible result.

High-Quality Matcha: Opt for a ceremonial-grade matcha for the smoothest flavor, especially if you plan on drinking it without additives. The quality of the powder significantly impacts the final taste.
Cold Filtered Water: Using high-quality water is essential, as the cold brewing method highlights the pure flavor of the tea.
Sealed Container: A water bottle, mason jar, or protein shaker with a tight-fitting lid is ideal for the shake method.
Fine Mesh Strainer: A small sieve is crucial for sifting the matcha powder and preventing clumps.
Whisk Ball (Optional): Many protein shakers come with a wire whisk ball, which works exceptionally well for breaking up matcha clumps.
Handheld Frother (Optional): An electric frother is a great alternative to shaking for a smooth, foamy texture.

Simple Cold Brew Matcha Recipe

This recipe uses the effortless shake method for a quick and perfect cup every time.

Frequently Asked Questions

Matcha powder does not dissolve completely in cold water; rather, the fine particles are suspended throughout the liquid. This is why it's important to shake or whisk it thoroughly and give it a quick stir before each sip, as the powder will naturally settle over time.

To prevent clumps, always sift the matcha powder through a fine mesh strainer first. Then, either use the vigorous shake method in a sealed bottle for about 30 seconds or use a handheld electric frother to create a smooth mixture.

While you can use culinary grade matcha, ceremonial grade is recommended for cold brew, especially if you are drinking it plain with just water. Ceremonial grade has a finer texture and superior flavor, which is more noticeable without the addition of milk or sweeteners.

Yes, the flavor profile is different. Cold brew matcha is generally smoother, less bitter, and has a naturally sweeter, more mellow taste. Hot brewing extracts more tannins and umami flavors, which can result in a bolder and more astringent taste.

Yes, cold brew matcha retains all the antioxidants and L-theanine of hot matcha. Additionally, because it is prepared without heat, it may better preserve delicate, heat-sensitive compounds like chlorophyll and Vitamin C.

Yes, you can make a larger batch and store it in the refrigerator for up to two days. The matcha particles will settle to the bottom over time, so you will need to give the container a good shake or stir before serving each time.

For convenience, a shaker bottle with a tight-fitting lid is excellent. A mason jar also works well. For a perfectly smooth and frothy texture, a handheld electric frother or a traditional bamboo whisk can be used.
