* [[Wort Souring]] is similar to sour mashing, except the brewer often uses a pure culture instead of adding grain to the kettle. Instead of souring the mash, the wort is transferred to the boil kettle and soured usually over the time span of 1-3 days with a pure culture, or with the wild yeast and bacteria found naturally on grain (grain is added to the kettle). Similar to the sour mashing process, the soured wort is usually boiled to heat pasteurize the wort (a process called "kettle souring").
* [[Mixed Fermentation]] refers to the process of fermenting a wild or sour beer with a culture that contains more than just Saccharomyces (or no Saccharomyces). These are often mixed cultures containing [[Brettanomyces]], [[Saccharomyces]], [[Lactobacillus]], and [[Pediococcus]]. Mixed cultures are available from multiple yeast companies such as [[Wyeast]], [[White Labs]], [[The Yeast Bay]], [[GigaYeast]], and [[Omega Yeast Labs]].

There are several brewing methods that are specific to sour and wild brewing. Different methods can be used separately or in conjunction with each other to help produce a desired result, or to produce a certain style of beer. For example, [[Berliner Weissbier]] is often brewed using the sour mashing or kettle souring methods. Another example is that kettle soured beers can be barrel aged with or without ''Brettanomyces''. By mixing different techniques for different specific reasons, brewers have created new and interesting results.
==General Fermentation Techniques==* [[SoleraMixed Fermentation]] is a fermenter management refers to the process that involves removing of fermenting a portion of aged wild or sour beer from with a fermenterculture that contains more than just Saccharomyces (or no Saccharomyces). These are often mixed cultures containing [[Brettanomyces]], [[Saccharomyces]], [[Lactobacillus]], and refilling that fermenter with fresh wort or young beer[[Pediococcus]]. The removed portion can be used in a variety of waysMixed cultures are available from multiple yeast companies such as [[Wyeast]], including but not limited to filling up a second stage solera fermenter[[White Labs]], blending with another beer[[The Yeast Bay]], packaging the beer[[GigaYeast]], or given additional aging on fruit or spicesand [[Omega Yeast Labs]].* [[Cereal MashingWort Souring]] is similar to sour mashing, except the brewer often uses a pure culture instead of adding grain to the process kettle. Instead of gelatinizing adjunct grains such as cornsouring the mash, ricethe wort is transferred to the boil kettle and soured usually over the time span of 1-3 days with a pure culture, or with the wild yeast and unmalted wheatbacteria found naturally on grain (grain is added to the kettle). Similar to the sour mashing process, so that their starches may be converted during the soured wort is usually boiled to heat pasteurize the wort (a saccharification restprocess called "kettle souring").
* [[Sour Mashing]] is a method that uses the wild yeast and bacteria that is naturally present on grain to quickly create acidity in a mash usually over a time span of 1-3 days. The soured wort is afterwards generally boiled to kill off the microorganisms that were present in the sour mash.
* [[Funky Mixed Fermentations]] refer to processes of using [[Saccharomyces]] and [[Brettanomyces]], and no souring bacteria. This results in a ''funky'' beer with interesting flavors from the Brettanomyces, but very low to no levels of acidity.
* [[Spontaneous Fermentation]] refers to the method of using yeast and or bacteria that is naturally present in the air, or on fruit, grain, insects, or other naturally occurring carriers.
* [[100% Brettanomyces Fermentation]] is the process of doing a primary fermentation with only [[Brettanomyces]] yeast.
==Specific Techniques==
* [[Commercial Sour Beer Dregs Inoculation]] is a process where unpasteurized commercial sour beers are used to ferment a sour beer. Generally only the last half inch of a beer is used, which is sometimes called the "bottle dregs". Commercial sour beers can be used by themselves, but are more often used in conjunction with another brewing method to add diversity to a mixed fermentation.
* [[100% Brettanomyces FermentationSolera]] is the a fermenter management process that involves removing a portion of doing aged beer from a primary fermentation fermenter, and refilling that fermenter with only fresh wort or young beer. The removed portion can be used in a variety of ways, including but not limited to filling up a second stage solera fermenter, blending with another beer, packaging the beer, or given additional aging on fruit or spices.* [[BrettanomycesCereal Mashing]] yeastis the process of gelatinizing adjunct grains such as corn, rice, and unmalted wheat, so that their starches may be converted during a saccharification rest.
