Making good wine? That's hard.
Sugar plus yeast = alcohol.
At a minimum (the Roman way) you need something to crush the grapes (they used slaves) and something to store the fermentable mess in until it ferments. Then you will need something to store it in like amphora or plastic jugs when you decant the wine from the must.
That's the minimum. To make good wine is beyond my scope in instruction. I can make fermentables that will make you drunk, but they might hurt you the next day.

You tinker around building things. Could you build something that crushes grapes, powered by squirrels? I think Marcella could put it to good use.
