The author, Steve-don't-eat-it, calls it prison wine, but I don't see why it wouldn't work at the end of the world. In one (pretty good) book I have read, getting drunk keeps the zombie virus from getting hold of your brains, so there may even be a survival (rather than entertainment) aspect to all this.
Steve Don't Eat it Vol. 8, 13 June 2005
"Prison hooch can be made in your cell toilet (as long as you don't mind using other people's toilets or finding some other solution), or more often, in plastic trash bags. The recipe is simple: make a strong bag by double or triple-bagging some plastic trash bags and knotting the bottoms. Into this, pour warm water, some fruit or fruit juice, raisins or tomatoes, yeast, and as much sugar as you can get ahold of (or powdered drink mix). Now tie off the top of the bag, letting a tube of some kind protrude so the thing won't explode while it gives off carbon dioxide. Now hide the bag somewhere and wait at least three days. A week is enough.
One of the problems you have right away with making wine in prison is the difficulty getting yeast. It's a strictly forbidden item and you might not be able to get any. In this case you can improvise the by using slices of bread, preferably moldy (but not dry) and preferably inside a sock for easier straining.
All of which is very fine and good, but in this case the author actually tries out the product (based on moldy bread in sock based yeast) and has considerable success. Sounds like a winner!
