By food saver, I am assuming you are talking about a 'food vaccuum'? I just bought a hand held one for $20 at Walmart by the expensive food saving machines. Won't know until tomorrow if it will work, but I use 5 gallon buckets as secondaries, with 3/8 vinyl tubing, waxed in to the lids and a balloon, for an airlock (not trying to be a vinter, just trying to make good, healthy, organic wine, for my husband and I). I try to keep them as full as possible, but I am concerned that if I do have to age any wine, after reading more and more on this site, I will have oxidation problems. So that is why I bought it. It works with those food bags that look like space bags, so I am hoping I can suck some air out through the tubing on my less full secondaries.
