==General Information==
The method of fermenting wort with only ''Brettanomyces'' was pioneered by Tomme Arthur from Pizza Port/Lost Abbey, and Peter Bouckaert from New Belgium in 2004 with their 100% ''Brettanomyces'' fermentented ''Mo' Bretta'', and Vinnie Cilurzo of Russian River with Sanctification later that same year <ref>[http://www.amazon.com/American-Sour-Beer-Innovative-Fermentations-ebook/dp/B00LV8IRRI/ref=dp_kinw_strp_1 American Sour Beers. Michael Tonsmeire. July 2014. Pg 189.]</ref>. Avery Brewing Co. and Jeff O'Neal from Ithica Beer Co. also produced early 100% ''Brettanomyces'' beers <ref>[https://youtu.be/IGzoh4brILA?t=20m59s Yakobson, Chad. Interview on Craft Commander. 12/20/2016. Retrieved 12/20/2016.] (~21 mins in)</ref>. This method was further popularized by Chad Yakobson's ''Brettanomyces'' Dissertation on the [http://www.brettanomycesproject.com/dissertation/ Brettanomyces Project blog], and by his brewery, [[Crooked Stave Artisan Beer Project]]. 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 it is believed that beer that is fermented with Brett in primary usually produces a surprisingly clean, lightly fruity beer (see Chapter 8 in ''American Sour Beers'' by Michael Tonsmeire for a full description of 100% ''Brettanomyces'' fermented beers). For However, much of this reasonbelief was partly based on the misclassification of what is now referred to as "''Saccharomyces'' Trois". The issue of characterizing 100% ''Brettanomyces'' fermentations is further complicated by the fact that some sources of ''Brettanomyces'' also contain ''Saccharomyces'' or other unadvertised microbes. Furthermore, most ''Brettanomyces'' strains cannot fully ferment wort that is characteristic due to not being able to utilize maltose (see the [[Brettanomyces#Carbohydrate_Metabolism_and_Fermentation_Temperature|''Brettanomyces'']] wiki page and [http://brettanomycesproject.com/dissertation/pure-culture-fermentation/impact-of American IPA has been found to create wonderful beers when primarily fermented with Brett-pitching-rate/ Chad Yakobson's Dissertation]).
Typical characteristics of Brett ''Brettanomyces'' primary fermentations (these are generalizations, and may not be true for every strain):* Most pure cultures of ''Brettanomyces'' cannot fully attenuate wort due to not fermenting maltose, especially under anaerobic conditions.
* Initially subdued "horsey", "funky", "barnyardy" flavors due to the lack of ''Saccharomyces'' esters/phenols (see the [[Brettanomyces#Brettanomyces_Metabolism|Brettanomyces Metabolism]] page for more information). However, this is a generalization and some brewers have reported getting some "funkier" flavors out of some strains.
* Light fruit characteristics.
