Using a still won't work as well as you might think (ok, I haven't done it but here's my logic .....)
1. Ethanol boils off at 172F as a mixture of 96% ethanol/4% water (an azeotrope)
2. Depending on the height of the column, the liquid in the pot likely reaches a significantly higher temperature so that the vapor at the top of the column is 172F
3. It's going to take a while to get all of the alcohol out of the pot so the remaining beer is undergoing heat stress this entire time
4. I don't know what temp the aromatic oils evaporate or if they decompose in the heat, but they'll likely be gone. Can probably add a bunch back by dry hopping the resulting beer, but without alcohol much of the antibacterial protection is lost and you risk contamination
I was thinking a vaccuum pump on a pressure cooker might work ....... my pressure cooker is aluminum so I don't know what taste effect that will have if I just put the beer straight in there. Maybe in bottle or pot inside the cooker.
