The recipe for turning fruit into wine goes something like this: 1. Pick a large quantity of ripe grapes from grapevines (you could substitute raspberries or any other fruit, but 99.9 percent of all the wine in the world is made from grapes, because they make the best wines). 2. Put the grapes into a clean container that doesn't leak. 3. Crush the grapes somehow to release their juice. (Once upon a time, feet performed this step.) 4. Wait.
