You can prepare beautiful Coldbrew Matcha in about 20 seconds, or even less once you've made a few - here's how you do it.
Start with icy cold water.
Pour it into the bottle, leaving an inch or two of headspace.
Add matcha -- 1 rounded teaspoon per 16 oz water. Add more matcha if you like a thicker taste.
Shake! As hard as you can for a good 10 seconds.
Hold the bottle an angle and rotate it -- you'll see matcha crema begin to build.
You're done! Drink it right from the bottle or pour into glasses (or, if you're getting fancy, into a carafe).
