What is the purpose of the Flavorlock bag?

The Flavorlock bag is specifically designed to allow gases, which are a natural byproduct of freshly roasted coffee beans, to escape while simultaneously preventing oxygen from entering the bag. This is crucial because when coffee beans are roasted, they release carbon dioxide, especially in the days following the roasting process. If this gas accumulates within a sealed bag, it can compromise the quality of the coffee by causing the bag to burst or by impacting the flavor negatively.

By utilizing a one-way valve system, the Flavorlock bag ensures that while the gases can escape, which prevents pressure build-up, no oxygen can penetrate the bag. Oxygen exposure can lead to staleness and degradation of flavor, so the sealed environment helps maintain the coffee's freshness for a longer period. Proper storage is essential for preserving the rich, complex flavors that coffee lovers appreciate, thus making the Flavorlock bag an effective solution for fresh coffee storage.
