Sour
A style which is deliberately acidic, such as Berliner Weisse, Lambics, Gueuze, Flanders Red Ale, American Wild Ale & Oud Bruin. There are numerous styles across many parts of the world which all vary in alcohol and colour. However, they all do have an offbeat flavour — acid-like, funky taste which is created by the introduction of one or a combination of fermenting agents (conventional and unconventional yeast).
