The invention provides an hourglass shaped apparatus for cold brewing coffee, comprising a brew chamber, and extract chamber and a middle unit connecting the brew and extract chambers. The extract and brew chambers comprise two ends of the hourglass shaped middle unit. The brew chamber houses a free-standing self-contained filter containing coffee grounds inside a water-permeable barrier. Water is poured into the brew chamber to generate coffee extract through cold water infusion. After the brewing process, the apparatus is inverted, and the coffee travels into the extract chamber through the middle unit for dispensing. Coffee brewed in this manner is less acidic and more flavorful than the conventionally hot-brewed beverage. All the components of the apparatus, the filter, the brew chamber, the extract chamber, and the middle unit, are detachable.
