coldbrew matcha

Drinking matcha ice-cold is a revelation: there is nothing quite like it in terms of sheer refreshment, especially on a hot day. The rich matcha feels creamy, yet has a mere 4 calories per serving and about 25mg of caffeine, or about a quarter that of a cup of brewed coffee.

And it couldn’t be easier to prepare: simply combine coldbrew matcha with icy water – the icier, the better – in a water bottle, mason jar, or any clean bottle with a cap, and shake vigorously. We like to fill up a small pitcher with ice and filtered water, let that sit for a few minutes, and pour that very cold water (minus the ice) into our water bottle, add the matcha, and shake. We think it tastes naturally sweet on its own, but feel free to add your sweetener of choice if needed.

The proportions are 8 ounces of very cold water to 1 gram (roughly half a teaspoon), and shake vigorously. To make 16 ounces of coldbrew, use two grams (one teaspoon), and to make a quart, use 4g, or 2 teaspoons.

It will keep in the refrigerator for some time, and can be re-shaken, but it tastes best brewed up to enjoy right away.

    Our most elegant coldbrew. Aromas of baby vegetables, pea tendrils, and new grasses. It has an ultrafine, fluffy texture, heaps of chlorophyll, and its brothy umami comes out full force. SHOP

  • Breakaway Coldbrew Organic

    This is the most vibrant and alive organic coldbrew we've tasted. Grown and stone-milled in Kagoshima, Japan's semi-tropical deep south. Tastes like the smell of spring in Japan. SHOP

  • Umami galore makes this remarkable tea taste sweet. Has a creaminess that almost tastes milky, and, when properly prepared, creates a crema not unlike a Guinness draft. SHOP

When you want the real thing, look no further. We serve Breakaway Matcha to our guests as part of their nine-course tasting menu, and the response has been overwhelming. They love it, and we love it too.

We serve the Breakaway Blend 100 matcha. It is life-filled vibrant green with a round umami-laden flavor without any bitterness. We currently serve it much like an espresso with a lovely crema achieved with a foaming wand. And in the context of our cuisine, the Breakaway Blend 100 is a natural way to end the evening.

I drink my daily cup of Breakaway Matcha at mid-day, just before I go to work. It’s like yoga in a cup of deliciousness: it gives me clarity and focus, calm and a deeply centered feeling - which is wildly helpful in my job as a teacher in a classroom of lively five year olds!
