Wild Ale is an umbrella term for beers fermented or aged with non-standard or mixed cultures, including Brettanomyces, bacteria, or spontaneous microflora. The style is defined less by strict ingredients and more by fermentation character: acidity, funk, earthiness, or bright fruit notes that develop through time in tank, barrel, or bottle. Wild Ales can be clean and delicate or complex and rustic, but they all share one trait: yeast and bacteria that work outside the boundaries of conventional brewing strains. It’s a broad field that covers both fully spontaneous styles and mixed-fermentation beers shaped by the brewer’s hand.
