Sours are apt for aging if you are into that sort of thing. I'm not. I don't care for sour beers. I suggest aging a barleywine. Something with an original gravity above 1.100 and allow it to have a primary fermentation that exceeds 8 weeks, but not much more. Dry hop it and bottle it. Then allow 6 months of bottle conditioning. No less.
If it isn't a fantastic beer, it isn't my fault.
Do's: American Ale yeasts. American hops in generous portions, very cool fermentation temps.
Don'ts: European yeasts. Noble hops. Lager yeasts that claim to work well in ale temps.
Dear Lord Please don't: Lager yeasts (any kind), Warm fermentation temps (no exceptions)., simple sugar additions(corn sugar, cane sugar, even Belgium candy sugar), using anything other than barley (corn, rice, simple sugars), only use barley nothing else.
