On a shopping excursion, we found at least 15 cold-brew coffee makers that range in price from $20 to $252. However, you already might have a device that does the same as what these products do.
The most common type of cold-brew coffee maker is a single-serve, mug-size model. The more expensive models are coffee makers that steep 32 ounces of coffee.
The difference between cold-brew coffee and the easier-to-make iced coffee is the steeping process. Instead of just pouring coffee over ice cubes, cold brewing takes 12–24 hours. Coffee is extracted with cool water, introduced by full immersion or a slow drip that eliminates coffee’s normal acidity.
We aren’t convinced that cold-brew coffee makers are worth the investment. None of the models that we found expedite the hours-long process and, according to Benji Walklet, who runs The Coffee Concierge website, a cold-brew batch can be made with a French press machine. It takes some trial and error to find the mixture that best suits your tastes, Walklet says, but so, too, is the case with cold-brew coffee makers.
