We love a good sour beer, usually as a lower-alcohol alternative to wine or in the case of our wild-fermented ciders.
The sour culture makes a big difference when you make them. If you find a bottle you like, sanitize the lip, cover with sanitized foil, and then store in the fridge until ready to pitch. You can then add those bottles to a primary or secondary, and let the bugs go to town. They will duke it out until you get what becomes your house culture. It may take a few years to really develop. Remember that most of those wild beasties are going to permeate your soft parts, so keep separate hoses, gaskets, etc. just for your sours. I have a two-tap kegerator just for anything with wild bugs in it, currently a tapped-out passionfruit saison (about to become a guava cider) and a Bretted barley wine.
My house culture comes from the grapes that we grow; it's in multiple generations at this point, so whatever it is, it's ours. Generally, it's a fruity sour front, biscuity middle, and (generally) a sweet-tart (not the candy) finish. Depends on what we added to the fermenter, how long it aged, etc. We like our enamel, so we aren't going for that, but we like drier, so any residual sweetness is usually long-chain starches that didn't get eaten or fruit components we added to that batch.

If you go from enjoying to producing, it's a just some extra steps, a little more cleaning, and a lot of aging.
