Cold Brew

Cold brew is a popular way of making coffee in which the ground bean is steeped in cold (or room-temperature) water for a long time — usually 12 to 24 hours — and then strained.

The key difference from classic hot coffee is precisely the absence of heating. Since hot water intensively washes acids and bitter compounds out of coffee, cold brewing gives an entirely different result: the drink comes out extraordinarily smooth, mellow, sweetish, lower in titratable acidity (though its pH is similar to hot coffee), and almost without bitterness, but with a rich body and chocolate-nutty notes. Cold brew is served cold, with ice, often diluted with water or milk, since it is made as a concentrate. Refreshing and delicate, this drink is especially popular in summer. Cold brew is an example of how changing just one parameter (temperature) radically changes the character of coffee.
