Hot coffee on a cold day makes sense, but when the days turn warm, a tall glass of iced coffee seems exactly right, especially if it’s cold brew made with just the right beans.
To be clear, pouring hot brewed coffee over ice is a fine idea, even if it dilutes the drink a bit. But true fans of coffee know that cold brew is an entirely different coffee experience. Brewing or steeping coffee at room temperature extracts the best flavors in the coffee and leaves behind the bitter notes produced when you brew coffee in hot water. Cold brew is less acidic, but be aware that it packs a much bigger caffeine punch than traditional hot-brewed coffee.
While cold brew isn’t hard to make at home — it calls for coffee beans, water and 10 to 24 hours of patience — for those who don’t want to bother, there’s an exhaustive array of cold brew options in the supermarket refrigerator case, including bottles, boxes and cans of black coffee, plus coffee laced with oat milk, cream, chocolate, vanilla and more. Some are single-serve grab-n-go, others are “concentrated,” perfect for pouring over ice and diluting with milk. For this Taste-Off, we focused on plain black coffee, opting for lighter coffees when possible.
Great cold brew starts with top quality, expertly roasted beans. Lighter roasts tend to produce a smoother, almost sweet and flavorful liqueur that is stunningly delicious, highlighting the natural caramel-chocolate-citrus notes of the beans. Darker roasts lean slightly bitter and beg for a splash of something creamy to smooth out and balance the flavor.
Finding great cold brew coffee isn’t easy, as most labels offer little information about the source of the coffee or the amount of beans used. Some boast about the steeping time, yet the flavor of the finished brew is lacking, likely because the beans to coffee ratio is off or the process is flawed. Bad cold brew is watery or as bitter as day-old, rewarmed coffee.
