Coffeevacs have a unique patented airtight closure system, our 2 way valve, allows the carbon dioxide from the beans to slowly escape, without letting oxygen in. Solid and tinted models protect light sensitive beans and tea leaves. Coffeevac's save you money and guarantee smooth rich coffee flavor. The multi use Coffeevac can also be used for most dry & wet goods. Store conveniently on the counter top, in the pantry, the fridge or freezer.
