Why would you want a FoodSaver for homebrewing?
Vacuum sealers are indispensable for storing hops [See: 5 Recent Hop Finds]. You can save money by getting in on bulk hop buys. Use your vacuum sealer to break these up and to preserve freshness. You can also store specialty grains in vacuum bags or using the mason jar attachment. Other uses include: storing base grains, partial dry yeast packs and storing and preserving other beer ingredients.
