BIAB #10 - Wallonian Pale Ale...

After having such good success with my Sorachi Saison and with the weather being as warm as it had, it made sense to take advantage and brew another saison. Being all out of Sorachi, but wanting those sharp citrus notes, I checked my hop pantry. Thankfully I still had a substantial amount of whole leaf Citra and Summit pellets left and I was confident that combo would hit the mark. Around the time I was formulating the recipe Malt Miller Rob tweeted that he had just received a shipment of vials from Yeast Bay. I’d heard of these guys in passing, but wasn't really aware of their work so I decided to check them out further. It turned out these artisanal yeast wranglers have isolated and harvested a range of yeast strains that aren’t commercially available and then used the expertise of White Labs to culture the yeast into sellable quantities. Their Saison Blend sounded absolutely delicious, but sadly by the time I placed my order, the Malt Miller had already sold out. Thankfully, there were a few vials of the Wallonian Farmhouse still available, described as “the funkiest ‘clean’ yeast we have in our stable”. It sounded interesting so I dropped it in my basket (along with a vial of their Funktown Pale). I really wanted to get to know the flavour profile of the yeast so I kept the grain bill pretty simple, using only Vienna and a bit of torrified wheat. Checking out the information for the yeast on the Yeast Bay website it warned that it “exhibits absurdly high attenuation, resulting in a practically bone-dry beer”, so to counteract I upped my mash temp a little to around 76°C to throw some unfermentables into the mix. This looked to have worked a treat as it fermented out bang on 1.010. Well, once again I got to sample the beer before I got around to writing this article. I found the end result quite surprising and was expecting massive amounts of farmhouse funk. What I ended up with was a subtle saison that was indeed very clean, more of a pale ale saison. It was certainly an interesting yeast to work with and I will probably look at grabbing a vial of the Saison Blend I originally had my eyes on at some point. I chose to throw this in a couple of EasyKegs to take to the recent Homebrew Camp meetup, where the chaps there seemed to enjoy (or they were just being polite!).
