I gave this a shot - worked pretty well actually.
I basically was watching football and did another pass through the filter during the commercial breaks. I went for 6x first, then went all the way to 20x the following day. Crown Czar ($8.25 / 750 mL) was at least as good as the Skyy but wasn't as smooth as the VOX I used as a comparison (with the 6x). The unfiltered tasted like garbage. After I finished my project I ran some water through the filter and then put it in a sandwich baggie... you want to keep it sealed, sterile, and not let it get bone dry again. I used the filter the following week without problem.
The other Chemistry grad students out here are very interested in a pitcher party.
