Cold-brewed coffee sales have shot up 339 percent in the last few years, and 115 percent in the last year alone. Yet it's as basic as its name implies: coffee brewed without heat. But that cool factor creates something...well, special. No boiling makes coffee less acidic, mellower, and slightly sweet, which means you're less likely to spoon in sugar. That sweetness also makes it ideal for smoothies, milk shakes, cake and muffin batters, and even cocktails.

A little goes a long way, too: Cold-brewing concentrates the flavor, so it's typically diluted 50/50 with water, milk, ice cubes, or other liquids. And unlike hot-brewed coffee, which tastes drastically different after it cools, cold-brewed's flavor doesn't change, which means you can keep a stash in the fridge for up to two weeks. You don't need any special equipment, either—just ground coffee and cool water.

So why do coffeehouses charge about $4 for a cup of cold-brewed coffee when it has the same ingredients as hot? The same reason theaters charge $8 for a tub of popcorn that costs 90 cents to make. So brewing your own, which costs less than $1 a cup, is like getting a $3-off coupon—every day!
