Abstract
A method for delivering a short coffee extract faster from a closed capsule containing ground coffee by injecting water under pressure within the capsule. The capsule is filled with ground coffee, has a delivery membrane and is extracted in a coffee extraction device and pressurized water is injected in the capsule under pressure. The coffee beverage is released through the beverage delivery membrane of the capsule with engaging means engaging in and/or against the membrane. The pressure loss is reduced in the coffee bed by providing ground coffee having a reduced percentage of fines (F) depending on the average particle size (D4,3). The extraction yield is maintained between 15 and 30% and the coffee extract of 25 or 40 grams is delivered in a flow time of 20 seconds or less.
