Igorian, I was reduced to making my own sherry. I put a two litre tub of home made wine in the freezer overnight. Next day I turned the frozen block out into a big strainer and began to sample the liquid that dripped from it's bottom corner. It was ice cold and it tasted exactly like the sweet white wine I started out with, so that was a waste of time.
But as I drank more of it I noticed two things: firstly, the block of frozen wine was turning very pale at the top and, secondly, the floor was no longer level! Happy days.
