The Cold Brew Green Tea Starter Kit is a convenient and transportable brewing set for a cold, refreshing genmaicha cold brew. It includes a 100-gram packet of Cuzen’s original Organic Genmaicha blend and our uniquely designed filter-in bottle.
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. Genmaicha is a blend of green tea leaves 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.

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.
