How to Make Cold Brew Coffee
There’s something special about refreshing cold brew, and it isn’t just the caffeine. It’s the clink of ice in a glass, the steady pour, that first crisp sip of chilled coffee. When you compare iced coffee vs. cold brew, they’re totally different experiences. Keep reading to find out what makes cold brew coffee unique and how to enjoy it at home.
Iced coffee vs. cold brew: What’s the difference?
Iced coffee is simple: It’s hot-brewed coffee that you pour over ice cubes to make it cold. The problem is that water dilutes the coffee flavor, so you have to start with extra-strong coffee (like what you get in this Mint Mojito Iced Bulletproof Coffee recipe).
If you’re looking for bold coffee flavor without any guesswork, cold brew coffee couldn’t be easier.
Cold brew is coffee that’s never been heated. Instead of using hot water to extract the coffee, you steep coffee grounds in cold water for several hours. The result is coffee with a smoother and sweeter taste because the cold brewing process lowers the acidity and bitterness of your brew.
Benefits of cold brew coffee
Sure, you could just pop leftover hot coffee in the fridge—but that’s just cold coffee, not cold brew coffee. When you use the cold brewing method, you get a few unique benefits:
- It’s easy to make. Combine coarse ground coffee beans and water, toss it in the fridge (or let it sit at room temperature) and forget it for at least 12-24 hours.
- It’s less acidic, which brings out the sweeter, more subtle flavors. The mellower flavor will highlight the subtleties of a high-quality roast. Cold brewing is also a more forgiving method if you’re working with older coffee beans.
- The flavor doesn’t get stale or fade. Cold brewing produces super-concentrated coffee, which means you can dilute it with water or your favorite milk to taste. Cold brew concentrate lasts up to two weeks in the fridge, so you’ll always have coffee on tap.
Ready to make a batch? Here’s a basic cold brew coffee recipe using a 4:1 ratio of water to coffee beans, but treat this as your starting point. Use more water or coffee beans to taste. Use either cold water or room temperature water. And experiment with different brew times until you find your sweet spot.
