This Cheap, No-Mess Cold Brew System Offers A Hassle-Free Caffeine Fix

Cold-brewing is a great way to enjoy coffee on a hot day. We’ve shown you how to make it in a blender before, but this is a simple alternative.

Author and Boing Boing co-founder Cory Doctorow (and friend of Lifehacker!) explains how his system works. All it takes is a coffee grinder, a $10 “nut milk” bag and a plastic jug. Here’s how to produce the drink:

Every night before bed, I ground up about 15 Aeropress scoops’ (570 ml) worth of espresso roast coffe, leaving the beans coarse. I filled the bag with the grind, put it in the bottom of the empty jug like a huge tea-bag, and topped up the jug with tap water (distilled water would have been better — fewer dissolved solids means that it will absorb more of the coffee solids, but that’s not a huge difference). I wedged the top of the bag between the lid and the jug and stuck it in the fridge overnight.

In the morning, I took the bag out of the jug and gave it a good squeeze to get the liquor out of the mush inside. Add water to the jug to fill to the brim and voila, amazing cold-brew. You can dilute it 1:1 or even further.

That’s all there is to it. Doctorow notes that cleanup is as simple as inverting the bag over the trash and rinsing it off, and the rig produced excellent coffee concentrate with very little grit at the bottom of the jug. If you’re interested in trying cold brew, it’s an easy way to get started with great results. Hit the link below to read more.
