ABSTRACT:
An hourglass shaped apparatus for cold brewing coffee, comprising a brew chamber, an extract chamber and a center piece connecting the brew and extract chambers. The extract and brew chambers comprise two ends of the hourglass shaped apparatus and the center piece comprises middle portion. The brew chamber houses a free standing self-contained filter assembly containing coffee grounds inside a micro-fine wire mesh. 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 center piece 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 assembly, the brew chamber, the extract chamber, and the center tie piece, are detachable.
