Abstract

Disclosed is a method for producing a coffee extract with less bitterness, the method comprising the steps of: a) providing a coffee brewing vessel comprising an intimate mixture of coffee grounds and an aqueous medium; b) reducing the pressure in the coffee brewing vessel so as to be in the range of 3.4 - 84.7 kPa (1-25 inHg); c) brewing the coffee at reflux whilst maintaining the pressure in the range of 3.4 - 84.7 kPa; and d) increasing the pressure in the coffee brewing vessel to atmospheric pressure. Also disclosed is Caffe` Depurato obtained by the above method which has a noticeably improved flavour relative to other conventional brewing processes, and which also possesses less bitterness. Further disclosed is a coffee reflux extraction apparatus comprising: a coffee brewing vessel; a cannula; one or more vacuum pumps for reducing the pressure in the coffee brewing vessel to the range of 3.4 - 84.7 kPa (1-25 inHg); a steam condensing means having an evacuation means; and a collection vessel having a collection vessel evacuation means; wherein the apparatus is configured for the extraction of coffee grounds at reflux for a predetermined time period at a pressure in the range of 3.4 - 84.7 kPa (1-25 inHg); and wherein the apparatus is further configured to subsequently transfer hot liquid from the coffee brewing vessel into the collection vessel via the cannula under the action of a pressure differential provided by one or more of the vacuum pumps and mediated through said evacuation means.
