We offer a low minimum order quantity of just 25 stand up pouches ordered through our Roastar Design Lab™.

Let’s talk science — gather ‘round, coffee snobs. Gases (including a bunch of carbon dioxide) are emitted after roasting and continue to emit even after your coffee is packaged. If the gases are trapped inside the package, this can cause the bag or pouch to inflate or bloat (not cute).

Here’s where the degassing valve magic comes in. When pressure inside a sealed package increases beyond the valve opening pressure, a membrane in the valve momentarily opens to allow gas to escape out of the package. As gas is released — and the pressure inside the package drops below the valve close pressure — the membrane reseals. This one-way air valve is added to fresh roast and ground coffee bags to allow the carbon dioxide to easily escape and prevent more oxygen from entering, slowing the rate of reaction and increasing the lifespan of your lovely coffee. Mm, coffee.
