A catch-all American craft category for sour ales with fruit additions — from quick kettle-soured golden ales with tropical fruit purées to long-aged mixed-fermentation sours with stone fruit or berries. Typically 4.5–8.0% ABV. The defining feature is that both the sourness and the fruit character are prominent; neither dominates to the exclusion of the other.

Origin
The fruited sour ale grew out of the modern American craft movement, as brewers who had taken inspiration from the classically sour beers of Belgium — lambic, oud bruin, Flanders red — began developing what amounts to a new-world family of sour beer. Two distinct approaches converged on the same idea of pairing acidity with fruit. The first is patient and traditional: aging beer for months in oak, often on whole fruit, until lactic and wild-yeast character builds a complexity reminiscent of the Belgian originals. The second is fast and modern: souring wort with lactic bacteria in the kettle before a clean fermentation, then adding fruit purée or juice, which turns a sour beer into something quick to make and easy to drink. Fruit suited both methods well, and the bright, approachable results helped carry sour beer from a connoisseur’s curiosity toward a broad audience. The category is codified loosely enough to cover both the barrel-aged and the kettle-soured ends of the spectrum.
Notes
The defining balance is that both the sourness and the fruit read clearly — neither buries the other. The style sits close to several traditional sour beers: Belgian fruit lambic, Flanders red, and the contemporary fruited gose all share a tart-and-fruity profile, but the American fruited sour is a deliberately broad umbrella rather than a single recipe. Barrel-aged examples can show oak tannin and a leathery, barnyard funk from wild yeast, while kettle-soured versions tend to be cleaner and more straightforwardly fruity. Quick kettle souring made tart beer practical to produce at volume, which is much of why the style spread so widely.
