Cold brewing rids coffee of its acidity and bitterness. More than that though the Arctic Cold Brewer also wants to rid you of the need to brew up fresh coffee every day. Fill Arctic’s micron filter with ten to fifteen tablespoons of coffee, submerge the grounds in cold filtered water, cap it, then place the whole borosilicate carafe in your fridge overnight. The next day you’re left with about 50 ounces of a caffeine-packed coffee concentrate that can be diluted to taste, for example mixing 1:2 with cold water or even with hot water to warm up in the winter months. The concentrate stays fresh in a fridge for up to two weeks so regardless of consumption each brew should last awhile.
