In my pre-still days, I used to make milk wine pretty often. I also freeze jacked it a few times and it came out like licor de leite, the Portugese milk liqueur - very nice! Apparently, milk ferments produce far less in the way of fusels and other bad stuff, so even when concentrated by the jacking process, there's not so much in the way of hangover-inducing nasties. The pioneer of milk wine was an Alaskan priest. He claimed alcohol was not the work of the devil, fusel oils were. Here's an old newspaper article about him:
