Sour beer is beer which has an intentionally acidic, tart, or sour taste. Traditional sour beer styles include Belgian lambics, gueuze and Flanders red ale, and German gose and Berliner Weisse.

Brewing [edit]

Unlike modern brewing, which is done in a sanitary environment to baby-sit against the intrusion of wild yeast,^[1] historically the starter used from one batch to another usually contained some wild yeast and bacteria.^[2] Sour beers are made past intentionally assuasive wild yeast strains or bacteria into the mash, traditionally through the barrels or during the cooling of the wort in a coolship open up to the outside air.^[iii] ^[4]

The almost common microbes used to intentionally sour beer are the bacteria Lactobacillus and Pediococcus, while the fungus Brettanomyces can likewise add together some acerbity.^[1] Another method for achieving a tart season is adding fruit, which directly contributes organic acids such as citric acid.^[4] ^[five] Additionally, acid can be directly added to beer or added by the use of unusually large amounts of acidulated malt.

Depending on the procedure employed, the uncertainty involved in using wild yeast may cause the beer to take months to ferment and potentially years to mature.^[1] However, modernistic methods allow sour beer to be created within a typical timeframe for ales, usually several days.^[6]

Breweries [edit]

Making sour beer is a risky and specialized class of beer brewing, and longstanding breweries which produce it and other lambics frequently specialize in this and other Belgian-fashion beers. Established in 1836, one of the oldest breweries still in operation that produces sour beer is the Rodenbach Brewery of Roeselare, Kingdom of belgium.^[vii] Sour beer has besides spread outside Belgium, to other European countries, the United States and Canada.

In the United kingdom of great britain and northern ireland sour ales are produced by a few different breweries, including - Thirsty Pioneers Brewing Company, Elgood's, Wild Beer Co, Brewdog Overworks, Docks Beers, Mills Brewing, Shindigger and Bundobust (in house) Brewery

Sour beer styles [edit]

While any type of beer may be soured, most follow traditional or standardized guidelines.

American wild ale [edit]

Beers brewed in the United states of america utilizing yeast and bacteria strains instead of or in addition to standard brewers yeasts. These microflora may exist cultured or caused spontaneously, and the beer may exist fermented in a number of different types of brewing vessels. American wild ales tend not to have specific parameters or guidelines stylistically, simply instead simply refer to the apply of unusual yeasts.

Berliner Weisse [edit]

At i time the about pop alcoholic beverage in Berlin, this is a somewhat weaker (commonly around 3% abv) beer made sour past use of Lactobacillus leaner. This blazon of beer is commonly served with flavored syrups to rest the tart flavor.^[8]

Flanders red ale [edit]

Flanders red ales are fermented with brewers yeast, then placed into oak barrels to historic period and mature. Ordinarily, the mature beer is blended with younger beer to adjust the sense of taste for consistency. This is also sometimes referred to equally "flemish red".^[9]

Gose [edit]

Gose is a tiptop-fermenting beer that originated in Goslar, Germany. This mode is characterized by the use of coriander and common salt and is made sour by inoculating the wort with lactic acid bacteria before primary fermentation.

Lambic [edit]

Lambic is a spontaneously-fermented beer made in the Pajottenland region around Brussels, Belgium. Wort is left to cool overnight in the koelschip where information technology is exposed to the open air during the wintertime and leap, and placed into barrels to ferment and mature. Virtually lambics are blends of several seasons' batches, such every bit gueuze, or are secondarily fermented with fruits, such as kriek and framboise. Every bit such, pure unblended lambic is quite rare, and few bottled examples be.

Oud bruin [edit]

Originating from the Flemish region of Kingdom of belgium, oud bruins are differentiated from the Flanders reddish ale in that they are darker in color and not aged on wood. As such this style tends to use cultured yeasts to impart its sour notes.
