How to Cold Brew Green Tea

Cold brewing can be a great way to enjoy green tea on a warm day. Not only does the temperature of the tea stay cool and refreshing, but the flavor is also different as well. The cool water extracts less of the bitter components from the leaves, so you’re left with a smoother and sweeter tea. 

In this article, we’re going to walk you through how to prepare your own cold brew green tea at home. This is easy to do and really doesn’t require that many tools.

First, you’re going to take a pitcher. Ideally you have a pitcher that has a built in strainer, but if you don’t have one of these, you can always pour the leaves through a strainer later to filter them out. Set the pitcher down and then put in 5 grams of tea leaves. Our sample packs are already weighed out at 5 grams so you can use one of these to prepare the tea. If you don’t have a scale at home, a tablespoon of dried loose leaf Japanese green tea comes out to about 5 grams. 

If you would like a stronger cold brewed tea, you can double the amount of leaves you use and go for a full 10 grams. This may be too strong for some people, but as the cold brew method produces a milder taste profile, you may prefer it.

Once you’ve added in your tea leaves, you can then pour in 500ml of cool water or about 2 cups. This works both with room temperature water or water that has been chilled. The cooler the water, the less bitterness is extracted. 

Once the water has been added, you can just let the leaves sit for about 3 hours. If you really want to maximize the flavor, you can leave the leaves in overnight and then drink the tea in the morning. You can either leave the pitcher in the fridge to chill the tea slightly, or just leave it out. When the tea is done brewing, you can just pour it out through a filter and enjoy your cold Japanese green tea.

Now that we’ve covered how to prepare cold brew green tea, let’s go through some of the best teas to use in a cold brew. We’ve decided to highlight 5 different ones that work incredibly well when prepared cold.

First is the shizuku sencha. This tea is specifically designed to make the ultimate cold brew, made by mixing sencha leaves with matcha powder. The matcha powder gives it a stronger flavor and a dense, cloudy infusion. Here you’ll really get a taste of these sweet vegetable notes.

The second best green tea for cold brew has to be the Fukamushi Yamaga. This tea has been steamed for a longer time, which further breaks down the cell membranes of the leaf, allowing more of the leaf to be extracted. That’s why you see Fukamushi teas take on this deep jade green color. The deep steaming process also renders these teas smoother and in some cases fruitier. When prepared as a cold brew, you can begin to pick up on the subtle lychee berry note from this tea. If you think cold brew teas are weaker in flavor, this might be a good one to change your mind!

The next great tea for cold brewing is the Karigane Sakamoto. This tea is made by mixing the stems and leaves of the tea plants used to make Gyokuro. When prepared as a cold brew, this tea begins to take on these cool cucumber notes with a hint of cantaloupe melon. Definitely a perfect cold tea to enjoy in the summertime!

Next we have the Noike Hojicha. While most may think of this roasted tea only as a hot drink for the fall or winter, it works very well as a cold brew. When you cold brew a roasted tea like this, you get even more of the sweet coffee, chocolate and caramel notes and less of this more wooden or smoky flavor. This was first introduced to us by the producers at Marufuku in Shizuoka, who had a big pitcher of cold brewed Hojicha waiting for us when we met them.

Finally, we come to the classic Gyokuro Sasa Hime. This is our middle tier Gyokuro from Mr. Sakamoto, made by blending the Yabukita, Okumidori and Saemidori cultivars together. Because this is a blended tea, it has a smooth complexity to it that is well extracted by the cold water. This creates a smooth, sweet and savory infusion that we really like to enjoy in the morning. 

Hopefully you get a chance to try at least one of these 5 teas as a cold brew at some point. Cold brewing can be a great method to learn in case you want to enjoy tea without drinking a hot beverage.
