Cold brew coffee is all the rage, especially when the thermostat threatens to explode. The brewing process creates a smooth-tasting, low-acidity drink that can stay fresh for up to two weeks in the refrigerator and is higher in caffeine content than regular iced coffee (to which we say, hell yes). The finished product is super concentrated—it’s best to dilute with water or milk and serve over ice. The basic technique varies by gadget but is surprisingly easy—simply combine coffee, water, and time (12 to 24 hours, ideally) to make the concentrate. And you can use it to make a hot mug of coffee too; simply add warm water to the concentrate instead of cold. The result: a full-bodied, rich cup of Joe every time!
Many cold brewers can perform double duty and also make iced tea or fruit infusions (although those drinks won’t last as long in the fridge as the cold brew coffee concentrate).
