How to Make Flash Brew Iced Coffee

What is flash brew iced coffee?

Flash brewing uses hot water, just like a hot cup. In this technique you less hot water and drip coffee directly over ice. The ice immediately cools the coffee and locks in the coffee flavors. The resulting brew has all the flavors of a hot cup, but with the added advantage that you actually want to drink it on a balmy afternoon.

How does the flash brew method compare to cold brew?

We are generally agnostic about brew methods, each has their place, depending on the desired result. For cold coffee methods, we offer this simple rule of thumb: for those who prefer light roasted single origin coffees, enjoy acidity and tend to drink coffee black, flash brew methods are going to produce a better cup. For those who want a full bodied, low acid cold coffee that is a great platform for milk or cream, cold brew is the way to go.

Flash brew, because of the hot water, will extract more acids than cold brew. This is particularly well suited for light roasted coffees which are selected and roasted for the distinct acidity and delicate aromatics that makes up their origin character. 

Both brew methods make cold coffee but the flavor profile is completely different. Flash brew, because of the hot water, will extract more acids than cold brew. This is particularly well suited for light roasted coffees which are selected and roasted for the distinct acidity and delicate aromatics that makes up their origin character. Acidity can be highly pleasant in a cold drink, so this technique is a great fit for those who like to drink their iced coffee black or with a touch of sugar but no creamer.

Cool down in a flash with this simple iced coffee recipe that is crisp, refreshing, and delicious. Instead of waiting hours for cold brew, or chilling hot brewed coffee, this easy method requires brewing a coffee concentrate directly over ice. The result is an instantly chilled coffee that is ready to serve in less than 10 minutes.  The best part is that you don’t need fancy equipment—almost any manual drip or pour-over style brewing device with a filter will do. This easy method can also work with some automatic drip machines.
