摘要： Method for producing a long coffee extract from a capsule in a coffee machine comprising: providing a capsule containing a predetermined dose of roast and ground coffee and the machine supplying hot water within the capsule, extracting liquid coffee extract from the capsule by rotating the capsule about its central axis in the machine for centrifuging and extracting the liquid coffee extract towards the periphery of the capsule while the machine continuing supplying hot water, the machine collecting the liquid coffee extract from the capsule and dispensing the coffee extract in a receptacle; wherein the liquid coffee extract is formed with coffee foam (i.e., 'crema') which exhibits, in a receptacle of reference, an initial height higher than 15 mm in the receptacle,such coffee foam being stable by retaining more than 50% of its initial height at 180 seconds after extraction and, wherein the roast and ground coffee has a weight of from 11 to 14 grams, a mean particle size D
4,3 of from 200 to 500 micrometer and a roasting degree of from 50 to 80 CTN.
