Volcanic Coffee is a premium coffee using AA arabica beans roasted to a medium dark profile. Coffee in it's green state is very stable but once roasted, it starts oxidising almost immediately. That gorgeous smell, is the flavour being released. That's why at the supermarket, you'll see coffee bagged in foil with one way valves - all in an attempt to keep the coffee from losing flavour too quickly. We say, buy little and often from your local roaster to keep it fresh and tasting at its best.
