You. Yes you, alcohol-consuming Californian. Go buy some grapes whilst they're cheap and make some wine.
I barely drink these days, but wine production is great fun and pretty damn easy. I've done it a couple of times, it was super rewarding.
It's much more straightforward than most booze (e.g., beer). You just need clean gear and mashed up grapes, and some sulphites on hand if things get a bit wonky. There's very little else to it.
I think anyone who drinks should make wine once in their life.
