The BN did an interview with Crooked Stave Artisan Beer Project earlier this year.  They specialize in all Brett fermentations.  Chad Yakobson, the owner, wrote the article in Zymurgy I believe.  There was a lot of good info during the interview.

Do you need to make a starter with a 100% brett beer?

Yep - most sources recommend lager pitching rates.

I've read (mostly on other posts in this forum) that Brett produces the most "funk" under stressful conditions. So if the purpose of all Brett beer is to really experience Brett's full character, wouldn't it be better to under pitch, at least slightly, to encourage ester production?

If you want funk, just pitch brett in a mixed fermentation.

When used in primary fermentation, brett needs to be treated as you would sacch. or it won't attenuate. Adequate pitching, aeration, temp. control.

Per C. Yakobson's paper, increasing acidity of the wort will yield more flavor compounds from the brett, but it may not be the funky flavors you're expecting - more along the lines of esters and phenols produced with belgian strains.

Huh, that's interesting. I know 'Wild Brews' says that Brett is only "super-attenuative" in the presence of other yeasts/bacteria, but I figured that it would produce a similar character regardless. Good info.

I did a 10 gallon saison batch split between 3711 French Saison yeast and WL677 Brett Troix in two primary fermentors. The 3711 blasted through like usual and finish at 1.005. The WL677 is still in a carboy, but it seems to have stopped at about 1.011. The taste out of the carboy for the brett beer is not very funky, and some interesting fruity esters. It is ready to bottle/keg and I will report back once it is carbonated.

I beg to differ with the "aeration" portion of that statement.  When I made my first all-brett beer, I had read that brett could produce sour notes in the presence of oxygen.  I wanted a little funk, but no sour, so I pitched at an ale rate and introduced no oxygen.  The brett (a dual pitch of White Labs' brett brux and lambicus) achieved 85% attenuation in about 3 weeks.  The beer turned out pretty good too.  What a weird yeast!

Russian River Sanctification is a great all Brett beer. Here is some info from Vinnie:

You could easily homebrew this beer at home as it is fermented in stainless steel and none of it goes into oak barrels. I don’t have an exact homebrew recipe though I think Brew Your Own has done some variations of the recipe though I don’t know which issue.

Here are some basics:

85% 2-row Malt
5% Vienna Malt
5% Wheat Malt
5% Acidulated Malt

OG: 1.058
TG: 1.006-1.010
ABV: 6.25%
BU’s: 25ish

Hops:
Styrian Golding 90 minute – beginning of boil
Sterling 15 minutes to go in boil

The yeast is a mix of Brettanomyces and bacteria’s.
50% Brett Brux.
10% Brett Claus.
10% Brett Lambicus
30% Russian River Brewing “Funky Bunch” house yeast culture

The RRBC house culture we call the “Funky Bunch” could be cultured from a bottle of Beatification

You’ll see a long lag phase at the start of fermentation and then a slowing of fermentation when it gets to 1.020, from there it has to sit for a couple of months before it gets down to the gravity listed above. Depending on if you bottle or not you will need to make a decision on the final gravity. If you do bottle it has to be bottled at 1.010 or so, but, not above that or the bottles will over carbonate and the bottles might explode.

Good luck,

Vinnie
People with experience, how long are we talking here?  On Teach a friend... As a club we made a big Am. Barleywine (OG 1.109).  Since no one was claiming the second runnings and was basically going to be dumped I collect it and brewed up a smaller beer (OG 1.044).  I pitched a packet of Wyeast Bret Lambicus and has been sitting in glass since.  I don't really see the typical wreath as I do with saccharomyces but the air lock looks as though it has pressure.

Yup. Brett likes to take time to start up. It's due to their nature - they are naturally slow growers and fermentors.

Yeah - the commercial examples of 100% brett beers have been fairly mild. "Brett Beer" from New Belgium / Lost Abbey is what comes to mind. If you told me it was a Kolsch, I wouldn't have argued. Soft, dry, and fruity. Really nice beer.

Brett is a different beast as a primary and a secondary yeast. I could go into detail, but I'd just be quoting Chad Yakobsen:

I've made a number of 100% Brett beers, and I love them. I pitch a big starter and aerate the wort. Most are done in 3 weeks or so, and get to 80-90% attenuation. The beers tend to have a lot of tropical fruit and a light tartness that is very appealing. I've mainly used Brett c. One character I've noted consistently is a brilliant clarity in the finished beer that is hard to achieve in a Sacc fermentation.

So, can you make a traditional style with it, for example, a porter or a pale ale, or are the beers on the sour side?  Tropical fruit sounds good in an English bitter or an APA, but sourness, not so much.

Hehehehe, you ABSOLUTELY can. Especially since Brettanomyces was named after British ales because the Brett flavors were typical for them about 100 years ago. I noticed that some Brett strains have a buttery feel and taste to them (probably diacetyl) which is also acceptable in English styles.
