Rest the beans
Much like red wine, the freshly roasted beans need to be allowed the opportunity to develop a decent flavour in the proper environment. This environment allows it to exhale CO2 without taking on oxygen. Placing it in an airtight container to early in the process will stem the development of the flavour. The #Sonofresco operating manual calls for a typical resting period of 48 hours - this tastes about right. Will see what a little more time does later on.
