Walk down any busy street in New York during the summer, and it seems like every other person is sipping an iced coffee. Over the past few years, the trend has shifted from the traditional cup of joe with some ice cubes to the more sophisticated cold brew, which is made by steeping grounds in cold or room temperature water for 12 to 24 hours to yield a more full-bodied, less-acidic coffee.
Though tasty and a welcome caffeine boost, cold brew is often not the most economical (a regular-sized cup can easily set you back $5) and making your own can be an arduous task. This is where Prisma comes in (h/t Mental Floss). The cold brew coffeemaker from home appliance company FirstBuild can produce an entire carafe of the refreshing java in 10 minutes or less.
How do they do it?
