Darker Roasts were shown to have a higher level of residual carbon dioxide relative to lighter roasts. ‘Light roasted coffee beans are still degassing 1 month after roasting’ In conclusion roast degree has a stronger impact than roast speed on the total amount and dynamics of degassing. This will have your coffee stale in no time. Coffee degassing is a major subject of interest recently by many baristas and coffee enthusiasts.Essentially the hot topics are coffee degassing, CO2 formation, CO2 release, coffee freshness, and optimal consumption time. The finer the grind, the larger the gas volume is released – making your coffee stale in a matter of hours. Get a vacuum pump and put your beans in a low-pressure environment to promote movement of gasses. In the present study, the effect of roasting temperature-time conditions on residual CO2 content and its degassing behaviours in roasted coffee was investigated. I've been looking into a storage container that will allow me to keep my coffee fresh. 3. Once coffee beans are finished roasting, however, they slowly begin to release the carbon dioxide naturally over time in a process known as “ degassing.” When hot water comes in contact with the beans, this process of “degassing” is sped up, resulting in the coffee bloom.
