I searched but couldn't find anything about this. Anybody every use a Vino Vac to try and preserve an unfinished bottle? If so, did it work or was it just a waste of the rest of the bottle?
I have only ever tried it on a cellared aged bourbon barrel imperial stout which had minimal carbonation to begin with... It worked fine but not sure how it would keep the carbonation.
Oobligatory man up post followed by more shenanigans. For real, just use a stopper and save yourself some monies.
Sounds like the vac is trying too hard. Just pop the cap back on, or use a simple wine topper and you'll be fine for a couple days.
Yeah, keeping the carbonation in and keeping the air out is what I'd be going for. Doesn't seem like that little plastic pump would suck all the carbonation out of the beer.
It would create a lower pressure environment in the bottle which would draw the carbonation from the beer.
It actually works great. The pressure you are applying does not have the force to pull the carbonation out of the beer. If you google it, I'm sure you can find the post where Mr. Oliver from Brooklyn Brewing says it his only way of saving an opened bottle of beer. I have weeks old beers that stand the test of it to boot. It is fairly standard practice actually.
In my opinion, no product exists that will maintain the quality of the beer once it is open. Pop the top and the quality will continue to diminish. For my money a simple wine stopper is sufficient if absolutely necessary. I operate under the philosophy that you never open a beer you do not intend on finishing. If it is too much to finish by yourself, you invite some friends.
I just put a new cap on them, and recap them.. But then again, I've got caps and a capper laying around that I don't use anymore since I keg.
I just use a champaign stopper. It's got a handle that expands the rubber stopper in the neck of the bottle to "recork" it.
cue in science wonk explanation of partial pressures and the exceptionally low % of atmospheric air that is actually carbon dioxide..... just cork it.
