Rich, sweet, and mellow, cold brew is popular for good reason! But you don’t have to pay a fortune at your local coffee shop to enjoy this cold treat. Cold brew is easy to make -- as long as you can wait 16 hours -- provided you follow a few key steps.
When you’re ready to start brewing, the first step is to grind your beans. Using a burr grinder (if possible), grind your beans to a coarse grind size. Your cold brew will be steeping for many hours, so you don’t want a finer grind.
Add the grounds to the coffee compartment of your cold brew maker or the main body of your French press.
Pour cold, filtered water into the cold brew maker, up to the fill line. Then place the lid on top, making sure it seals.
Leave your cold brew in the refrigerator for 12-18 hours, depending on how strong you like your coffee. Don’t leave it steeping for more than 24 hours -- your brew will end up over-extracted and bitter!
Take the grounds out once your cold brew is fully brewed. If your cold brew maker doesn’t have a great filter, you may want to pour the coffee through a filter (paper or metal) to catch the remaining coffee grounds.
Keep in mind that this process produces a cold brew concentrate, so you’ll want to water it down in your glass. The remaining cold brew concentrate should last up to two weeks in your refrigerator.
