Single Serve Iced Coffee Recipe

Andrew Pautler

Simple brew recipes are the best recipes. This single-serve iced flash brew recipe from Jake at @nosleeproastery is just that. Flash brew, or Japanese iced coffee, is the process of brewing coffee with hot water directly onto ice to instantly chill it and lock in the flavor and aromatics. The cold brew process can mellow out flavors to create an incredibly smooth profile. Sometimes that is what you want, but sometimes you lose some of the personality and boisterousness in a coffee in that process. For bright, fruit-forward coffees, I’ve found the flash brew process to be a better option.

This Japanese iced coffee recipe is designed for a single serving. Usually, I use 50% ice to 50% hot water when making flash brew. This recipe has a smaller ice to water ratio, but by pouring the brewed coffee over ice at the end, it helps to balance out the ratio.
