After it’s roasted, your coffee beans will keep on ‘breathing’ out gasses until it becomes stale. The one-way valve attached to the packaging helps getting out of this gas, keeping your coffee package from bursting out. Bag without valves clearly signs yellow light, as it means the coffee has been pre-staled or ‘aired’ before they are bagged. If the package doesn’t bloat, it’s either your coffee has run out of its freshness, or there is tiny hole somewhere on the packaging.
