I guess you could pull a vaccum at 30 inchs but with 5 gallons?...........it would take a LONG time to pull that much out of anything.
It would take time for sure, but it is possible, I got the idea a while back with a few beer threads about making N/A beer, it could be done with vacuum as long as you hit the right vacuum to boil the alcohol and not the water. never bothered to try it though, a deep vacuum could certainly help degas fairly quickly I would guess.
