One way degassing valve keep your roasted coffee FRESH!!!

Description:

Even after coffee is roasted, the beans continue to release CO2 gasses, which if not properly vented can give the coffee a gasses aroma and flavor. Un-vented bags can actually blow up like a balloon after filling with freshly roasted coffee, and the more coffee they hold, the more pressure is generated. Sealed coffee bags which are un-vented, often blow open after being stored due to the pressures caused from the release of the gas. The more oxygen the coffee is exposed to, the faster it loses its aroma and freshness.
