I took a break during my keezer build to head to a club members home. Last October we brewed up 65 gallons of a saison. After primary fermentation was complete, (
some of it with wild yeast that had been harvested from honey. See the Mute Dog Fermenting website to learn about the harvesting of this wild yeast strain by one of our club members. http://mutedog.beer/wild-yeast ), we then put it into a 59 gallon Pinot Noir barrel, that we had purchased.
I actually used White Labs Abbey Ale yeast (WLP530) for my primary fermentation. So this saison was in the barrel for almost 10 months. We had added some WLP650 Brettanomyces bruxellensis just after filling to add some farmyard funk to it.
We then brewed up a slightly different version of the saison recipe. I brewed 10 gallons this time. We took about 40 gallons of the saison brett out of the barrel (I got my 5 gallons in a keg and they are in the keezer carbing up). Then we refilled the barrell with 40 gallons of the new saison (the start of our Solera project!).
My ten gallons used the wild honey yeast from my buddies yeast bank of wild yeasts, as can be learned about on his website.
The beer we took out was at .998 final gravity!! It's dry, and crisp with just a slight farmy funk to it. Nothing over the top, but a really nice summer time drinker!
My initial saison addition to the barrel last October had a final gravity of 1.006 going in. Most of the others were at 1.004 to 1.006 range also. So the brett did do some nice work lowering the gravity about .007 points on the specific gravity scale.
Delicious beer. We're looking forward to what this Solera will turn out next. We'll take out about 20 gallons next time and put 20 gallons of new saison back in.
We intend to keep it going as long as we can.
