Cold brew green tea is naturally smooth and sweet with only muted bitter notes. It’s made by slowly steeping tea leaves in cold water. This process is optimal for the delicious combination of genmaicha. 


Genmaicha is a light and refreshing tea made by blending green tea with “genmai” or “roasted rice.” This unique combination deepens the rich umami profile of green tea with the toasty aroma of roasted rice. 

At Cuzen, we’ve elevated the popular pairing with our Single Origin Kirishima Okumidori matcha powder. This Cuzen-original has an even deeper umami flavor and a beautiful vibrant green color.


All the ingredients are certified organic and made in Japan.

Why choose cold brew?

  • Incredibly easy to make

    Cold-brewing green tea is effortless.  Simply add tea leaves to cold water and let it steep for a few hours.

  • Naturally sweet & full of umami

    L-theanine, the compound responsible for a tea’s sweetness, is easily infused into cold water. Catechin, the compound known for bitterness, dissolves much more slowly at low temperatures. This means cold brewing results in a smoother, mellow taste.

  • Low caffeine

    Cold-brewed tea is less caffeinated than hot tea because caffeine is more easily extracted in hot water. Using ice cold water further reduces the caffeine levels, making it a gentle green tea option.
