How to make Cold Brew Matcha

Some people call it cold brew matcha, some others call it iced matcha. Regardless of what you call it, matcha and cold water mixed together gets you cold brew matcha tea. This makes for a delicious and refreshing way to enjoy matcha and helps give you a great boost of energy on a hot day.

What exactly is cold brew matcha?

Unlike cold brew coffee, cold brew matcha is easy and quick to prepare. Cold brew matcha is simply made by mixing matcha in cold water. It is one of the best ways to enjoy an iced matcha green tea. Because all you need is to add the matcha powder to a bottle of cold water and then shake it up, you can make your own cold brew matcha in under a minute.

Drinking cold brew matcha tea means that you get to savor matcha in its pure form. When made with the correct matcha like our  Cold Brew Ceremonial Jade  blend, you get a refreshing cold matcha tea drink with a hint of natural sweetness. If you’re new to matcha, cold brew matcha tea is an excellent way of growing your appreciation for matcha.

What kind of matcha powder should you use for cold brewing matcha or iced matcha?

You will need to buy good quality matcha because you are only mixing it with water. It should be low on astringency and have a bright taste because the astringency will make your matcha cold brew taste like vegetable juice.

  • Avoid anything labelled as “culinary grade matcha”.
  • Try to purchase a ceremonial grade matcha. This should cost between $20 and $25 an ounce and the matcha powder should have a bright green color.
  • A standard serving will is 1 tsp, or 2 grams of matcha.

We recommend either our Cold Brew Jade Ceremonial Matcha or our Organic Ceremonial Matcha.

  • If you only drink matcha in the form of cold brew matcha or iced matcha, get our Cold Brew Jade Ceremonial Matcha.
  • The Cold Brew Jade Ceremonial Matcha is made from tea plants grown on a hillside in the mountains of Wazuka. It has a bright taste with a light and refreshing sweetness.
  • If you prefer variety and like to make different matcha beverages, use our Organic Ceremonial Matcha.
  • Our Organic Ceremonial Matcha has a great balanced flavor with a gently sweet aftertaste. It works well with cold brew matcha and iced matcha, but is also suitable for other matcha creations like lattes and matcha tea.

Generally, we avoid using matcha finished in the traditional Uji style when making any form of cold brew matcha or iced matcha. This is because the old masters in Uji prefer a heavier, umami flavor and frequently create their matcha blends to fit this profile. This is great when made into thicker matcha beverages, but it really detracts from the refreshing quality you would expect from a cold brew matcha or iced matcha.

What tools do you need to make matcha cold brew or iced matcha

Any vessel or container will work provided that it is:

  • Transparent
  • Has a wide mouth
  • Has a closeable lid

One of the wonderful things about cold brew matcha is that you do not need any special tools or equipment to make it. All you need is a bottle or jar with a secure lid. Our preferred method is to use a wide-mouth glass bottle. If you don’t have one, a Blender Bottle, mason jar or even a recycled glass jar works well too. Glass or transparent plastic is great because it allows you to see that the matcha powder is completely dissolved.

When do we drink cold brew matcha? How much caffeine does the cold matcha tea have?

On warmer days, you will often find us making some form of cold matcha tea in the office after lunch. The amount of matcha powder used in your cold brew matcha will determine the  caffeine content  . Generally, it supplies us with a much needed caffeine boost for about 4 hours. Just enough to remain productive for the rest of the work day. The L-theanine in matcha also helps us to calm down.

  • A cup of cold brew matcha tea or iced matcha made with 1 tsp of matcha powder will contain approximately 70 mg of caffeine.
  • The benefits of cold brew matcha is the same as matcha tea made with hot water.
  • Cold brew matcha and iced matcha have the same amount of antioxidants, and L-theanine as hot matcha tea.
