Split Batch Wild Farmhouse

The next for or five posts will be a backlog of brews, as I have been busy with school, work & interning. The first things to get cut when you are this busy are blogging and laundry.

The goal for this beer was to create a pretty standard saison grain bill, then split the secondary fermentation. Primary fermentation yeast was the same for both beers, Wyeast 3711 French Saison, which I feel results in a really nice, rustic, peppery farmhouse profile. Batch 1 fermentor would get a pitch of White Labs Brettanomyces claussenii in secondary and Batch 2 would also get Brett c. along with a smack pack of Wyeast Pediococcus.

Enjoying one of Ivan's outdoor open fermented farmhouse
Brett c. gives off awesome tropical aromas and flavors, with pineapple & mango usually most prominent from my experience with it. Pediococcus is a lactic acid producing bacteria, which also throws a lot of diacetyl (butterscotch off flavor/aroma) as a by-product. Luckily, brett will take that diacetyl and turn it into wonderful flavors and aromas.

I'm interested to see how Batch 2 will result for a sour beer. Up to this point, all my sours have had a plethora of different organisms, whether it be a sour blend from one of the big yeast companies, or from bottle dregs. I really wanted to see the results of a pitch of only pedio and brett.

I'm not yet sure what the long term plan is for both beers. Batch 2 will definitely require a year of aging for the pedio and brett to work on the souring process. I think Batch 1 will most likely be bottle conditioned, and savored for a few years to come.
