The sun's finally out in London, so it's time to repost last summer's cheap, easy, no-mess cold-brew coffee technique. This is the best cup of coffee you're likely to drink this summer.
I bought a $10 "nut-milk" bag and a plastic pitcher. Before bed, I ground up about 15 Aeropress scoops' (570 ml) worth of espresso roast coffee -- the $20 Krups grinder is fine for this, take no notice of people who claim the blade overheats and burns the beans; it doesn't even get warm -- leaving the beans coarse. I filled the bag with the grind, put it in the bottom of the empty pitcher like a huge tea-bag, and topped up the pitcher with tap water (distilled water would have been better -- fewer dissolved solids means that it'll 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 pitcher and stuck it in the fridge overnight.
In the morning, I took the bag out of the pitcher and gave it a good squeeze to get the liquor out of the mush inside. Add water to the pitcher to fill to the brim and voila, amazing cold-brew. You can dilute it 1:1 or even further.
Cleanup was easy: invert the bag over a composter, trashcan or garbage disposal, rinse off the bag, and you're ready to go.
This produced very, very good coffee concentrate, with only a little grit settled into the bottom 3mm of the pitcher (easy to avoid). It may just be the cheapest and easiest cold-brewing method I've yet tried.

My UK publisher, Head of Zeus, has published the official tour schedule for the British tour for Walkaway, with stops in Oxford (with Tim Harford), London (with Laurie Penny), Liverpool (with Chris Pak), Birmingham, and the Hay Literary Festival (with Dr Adam Rutherford). Hope to see you there!
My publicist just found an extra box of the cool promotional Walkaway multitools, and she’s generously offered to give them to the next 100 people to reserve tickets to the May 7th Walkaway event at Chicago’s Royal George Theater, where I’m presenting with CARDS AGAINST HUMANITY creator Max Temkin (current ticket-holders, don’t worry, you get […]
Carol from Cheapass Games writes, “In our continuing quest to bring back the very best classic Cheapass Games, we’re creating a new boxed set of Button Men, our strategy dice combat game. This time around, the characters will appear on cards, rather than pin-back buttons, but since they’re all 1950s era gangsters, the ‘button men’ […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
