One-way degassing valves
Freshly roasted coffee releases CO₂ for days. A one-way valve lets that gas escape while blocking oxygen — so bags don’t swell and the aroma stays in.
Reorder cycle: most roasters reorder every 2–3 months. This is the consumable that keeps the relationship alive between bag orders.
