Why Do Coffee Bags Need a Valve?
Freshly roasted coffee beans release carbon dioxide (CO₂), and if this gas remains trapped inside the packaging, it can cause the coffee bag to expand or even burst. Additionally, exposure to oxygen, moisture, and light can deteriorate coffee quality, leading to stale, flavorless beans.
A coffee bag with a valve is the perfect solution. The one-way degassing valve allows CO₂ to escape while preventing oxygen from entering, ensuring your coffee stays fresh, aromatic, and full of flavor for longer.
