100% Brettanomyces Fermentation

Remove headline about 100% brett beers being less funky + minor tweaks.
'''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]]'' (see [[Funky Mixed Fermentations]]).
==General Information==
===Starter Information===
When relying on a ''[[Brettanomyces]]'' culture for primary fermentation, a starter will often be necessary due to the fact that most yeast labs provide a small cell count for their ''[[Brettanomyces]]'' cultures. See the [[Brettanomyces#Starter_Information|Brettanomyces Starter Information]] section for more information on Brett starters.About 500ml starter per 25 liters of wort seems to be the current best practice. 
===Wort Production===
American IPA or American Pale Ale recipes are a tried and true general approach to making wort that is favorable to 100% Brett fermentations. Fruitier hops such as citra, amarillo, galaxy, etc. tend to compliment the light fruity characteristics of a Brett primary fermentation. The addition of body-increasing malts such as oats, unmalted barley, rye, wheat, or carapils may assist with the lack of glycerol that is typical for Brett <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1177290552299157/?comment_id=1177304778964401&reply_comment_id=1177435872284625&total_comments=4&comment_tracking=%7B%22tn%22%3A%22R0%22%7D Conversation with Tom Belgrano on MTF. 11/12/2015.]</ref>, but isn't always necessary. Otherwise, wort production can remain the same as it is for an American IPA/Pale Ale recipe. Aeration of the wort before fermentation starts should be done. This will greatly increase cell growth (see the [[Brettanomyces Propagation Experiment]]). As far as we know, acetic acid is a byproduct of ethanol production by ''Brettanomyces'' and not the prior lag phase, so as long as ethanol is not already being produced then acetic acid production is not a concern <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1204641279564084/?comment_id=1204674032894142&reply_comment_id=1204765566218322&comment_tracking=%7B%22tn%22%3A%22R%22%7D Conversation with Richard Preiss on MTF about oxygenating wort that will receive 100% Brett. 12/30/2015].</ref>. Examples of commercial 100% ''Brettanomyces'' beers that receive the same amount of initial aeration that would be typical of ales of their respective gravities are "Sanctification" from Russian River and "Mo’ Betta Bretta" from Lost Abbey <ref>[https://byo.com/hops/item/262-brettanomyces BYO Magazine. Brettanomyces. Steve Piatz. October 2005.]</ref>.
* Some microbiologists have witnessed that''B. claussenii'' is very slow to ferment wort by itself. If fermentation finishes in two weeks, this might be due to contamination of another yeast <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/1278391665522378/?comment_id=1278392922188919&reply_comment_id=1279087198786158&comment_tracking=%7B%22tn%22%3A%22R%22%7D Conversation with Lance Shaner on MTF regarding ''B. claussenii'' attentuation. 04/06/2016.]</ref>.
* Not all strains can ferment maltose, which is almost 50% of the sugar composition of wort. These strains should be avoided for 100% ''Brettanomyes'' fermentations. See [[Brettanomyces#Carbohydrate_Metabolism|''Brettanomyces'' carbohydrate metabolism]] for more details.
* In general a broad selection of various Brettanomyces yeasts is a safe bet to make sure fermentation carries through.
