I wouldn't give myself that much credit

but a wild*** guess would be 3942 which supposedly originates from De Dolle in West Flanders. If you have had a Wit brewed with this yeast you will note it is quite a bit more neutral than the 3944 which is supposedly the Hoegaarden strain acquired from the Celis brewery when it was in operation right here in Austin.

My personal take is that this has to do with barrel aging. I've never been able to get carboy fermented beers to sour adequately without pitching bugs in primary. However the two barrel aged sours a group of us did went through clean primary fermentations before being inoculated with bugs in secondary and ended up as sour as any of my bug in primary carboy beers. Not sure if the wood or the oxygen is to credit.

I think the bug strains at use at breweries are also to credit, the bugs from bottle dregs seem much more potent (in terms of amount of sourness produced, speed, temperature, alcohol tolerance range etc...) than the equivalent commercial strains from White Labs and Wyeast.

pure conjecture here, but maybe part of the reason barrel beers turn out more sour/funky is the fact that brett can metabolize wood sugars, so they have an additional source of food

Any body messed around with the red oak peg in the carboy for barrel simulated results?

I didn't really get better results than just using oak cubes, and the expanding wood cracked the neck of my carboy. A toasted oak dowel through a stopper would be a much easier alternative, but I'm still not sure the results justify the effort.

I'll be fabricating the oak peg for a carboy of mine in the next month or two for my Flanders Red later this spring. I heard of wrapping the peg in a fair ammount of teflon tape, I suppose to buffer any expansion of the wood thus cracking the carboy. We'll see how it all turns out when I cross that bridge.

I did the Teflon tape thing too, also if there is even the smallest amount of fermentation going on when you add the peg watch out for the pressure that builds up forcing beer out through the wood.

Wes, I have 4 sours going with the oak dowel process. The oldest went into the secondary in July I think. It is exhibiting a nice acidic nose as of last month, but I think it will get a more sour flavor as it ages through the summer when things warm up. I have no control to compare to, but I honestly think the oak is allowing a good amount of o2 into the beer below the pellicle. All but 1 of the beers were primereied with a sour strain in my case. I do have one sour going now without the oak dowel, but it has only been in the bucket with the bugs for like a month, so there is no sense in comparing that one, however it is freaking fantastic at its young age.

Next brewday I'm definitely picking your brain on your setup(s)
