'''100% Brett fermentations''' typically create a fruit forward beer that is less funky than if the [[Brettanomyces]] is pitched into a beer that has first been fermented with [[Saccharomyces]].
==General Information==
The method of fermenting wort with only Brettanomyces was popularized by Chad Yakobson's Brettanomyces Dissertation on the [http://www.brettanomycesproject.com/dissertation/ Brettanomyces Project blog]. While primary fermentation with Brettanomyces is a complex subject due to the wide range of characteristics of different species and strains of Brettanomyces, in general beer that is fermented with Brett in primary usually produces a surprisingly clean, fruity beer. For this reason, wort that is characteristic of American IPA has been found to create wonderful beers when primarily fermented with Brett.
Typical characteristics of Brett primary fermentations (these are generalizations, and may not be true for every strain):
* Lack of the typical "horsey", "funky", "barnyardy" flavors due to the lack of Saccharomyces esters/phenols (see the [[Brettanomyces#Brettanomyces_Metabolism|Brettanomyces Metabolism]] page for more information).
* Light fruit characteristics.
* A longer lasting hop aroma and flavor due to Brett's ability to constantly metabolize micro-oxygenation.
* A lack of glycerol, which is a compound that Saccharomyces produces which gives beer it's slick mouthfeel. Malts such as oats or flaked wheat are often used to make up for the lack of glycerol.
* Since Brett generally does not flocculate as well as Saccharomyces, cloudier beers are often produced if filtering is not used.
* Slightly longer primary fermentation in general (3-6 weeks).
==Starter Information==
When relying on a [[Brettanomyces]] culture for primary fermentation, a starter will often be necessary due to the fact that some most yeast labs provide a small cell count for their [[Brettanomyces]] cultures. See the [[Brettanomyces#Starter_Information|Brettanomyces Starter Information]] section for more informationon Brett starters.
