Turns out that all you really need to speed up the process of making perfect cold-brewed coffee is three nitrous oxide cartridges and a whipped-cream siphon. These cooking-instructor types take a step from the Modernist Cuisine playbook and show you how to produce cold and clear coffee concentrate from freshly ground beans in a measly 120 minutes, as opposed to letting the coffee steep for a day. Best of all, this novel cold-brew technique video even has an upbeat, synth-y score that would make Jan Hammer proud. Check it out, straight ahead.
