Wild & Sour Beers
A wild ale utilises wild yeast to initiate fermentation in place of a brewer's yeast. Sour beer has an intentional and perceivable acidic, tart or sour taste.
While there is a great deal of overlap between the two styles, a wild ale is not necessarily sour, and a sour ale is not necessarily wild.
Beers within these styles include Gose, American Sour, Belgian-style Lambic and Gueuze, and Berliner Weisse.
