Alcohol is really easy to brew and relatively easy to distill. Now, making good alcohol is another story.

But for that matter, growing good weed is another story and properly dry-curing it is too (it's not as simple as dehydrating the crap out of it to get good pot for smoking).

leave juice out in an area with yeast (so... almost anywhere) and the juice will ferment. You'll get more alcohol faster if you dump in some yeast (even the stuff for making bread would work, if we are trying to do this without anything designed to make alcohol)

It probably will be super gross at this point, but will get you drunk.

Search amazon for 'countertop water distiller' for under a hundred bucks, they'll ship you a "countertop water distiller" - run your spoilt juice through that thing a few times, and i'm not saying it will be good vodka; it won't... but it will be mostly alcohol, and it will be something you could probably choke down when mixed with something that tastes strong enough.

I mean, making booze that tastes good, that's an art. but if you just wanna get drunk? Probably easier than making decent bread.
