I use a moka pot (makineta) to make coffee, and I keep the beans in a bag (not sealed) in the freezer.
I keep getting people saying that in order to get to best aroma and the most fresh coffee the beans must be kept in vacuum after roasting until use, and due to this fact there is no escape but using the sealed Nespresso capsules and their machine (or any other capsule espresso machine equivalent).
How much does it matter? How much of the aroma/freshness is lost if the beans are not kept in vacuum? (but are being ground only prior to making a cup)
