The ideal would be a machine with two separate bean containers and two grinders, but they are rare, expensive or have other drawbacks.
The Moltio offers the next best thing: Interchangeable bean container and even a program to clean the grinder of the previous coffee remains after the change.
Can use this feature and you should buy for different bean varieties corresponding additional container, as this Saeco CA6803 / 00 Removable bean hopper. The containers are aroma-tight and can be used to stack the fridge. But more than two are not really necessary, since the remaining beans well decant from the containers in other suitable containers / cans and can be employed with new variety again.
Thus equipped, is in the morning a fresh coffee and later a neat fresh espresso just nothing in the way. And if a family member an entirely different species prefers is also the problem.
