In this they're starting with wine - why not just drink the wine? It says they make 5 gal (40 pints) of wine down to 6-8 pints; then drink half a pint - isn't it easier to just drink 2 pints of wine. Presumably the answer is in secretion of the drink.
How do they get hold of 5 gallons (~20 litres) of wine?
You make shine with things like potatoes instead of fruit. You're very much not going to want to drink 'wine' made out of potatoes or beets-but if you take that same 'wine' and distill it, you end up with something that doesn't taste so awful.
