Roasted coffee beans are delivered to an airtight container. The container is purged with CO2 or N2 until the O2 concentration is between 0.2 and 2%. The container is then sealed and the coffee beans are aged under an atmosphere consisting of CO2 or N2 with small amounts of O2. During the aging process, which involves a liberation by the coffee beans of a gas rich in CO2, the pressure in the container is maintained between 0.4 and 1.8 atmospheres. Aging may take place at temperatures between 20°and 25°C. and, under such circumstances, the O2 concentratio...
A process for treating roasted coffee, comprising the steps of admitting roasted coffee beans into at least one aging chamber; establishing an O2 concentration of between about 0.2 and about 2% in said chamber; and thereafter aging the coffee beans in said chamber at a temperature of about 20°-50°C. for a period of about 4 days to about 4 months, the aging step including establishing and at least substantially continuously maintaining in said chamber a pressure of less than about 1.8 atmospheres throughout at least a major part of said period, measuring...
