This beer came to me as I read a recent posting on The Mad Fermentationist's blog. I wanted to brew something I had never heard of prior, while still paying homage to the classic style of the Belgian Pale Ale. I chose to use Oat Malt as the base for this beer since I felt it would create a grainy and rustic flavor that would translate well with the dry/earthy/farmhouse flavors with the yeast and hop selections.
To ensure the oat malt converted, I added Amylase Enzyme to the mash, since this is not a naturally occurring component of oat as it is in barley. I think this addition is what created such a fermentable wort. The efficiency for this beer was much higher than my usually predictable 72-74%, but while it is not stylistically perfect, the higher alcohol may hide well behind the other flavors and esters going on in this beer.
For the mash, I went low, like 146-7* - this also helped create a more fermentable wort. To encourage some degree of souring (and to allow me to split the brew day in half) I did an overnight mash, and added acid malt to the grist.
Once boiled and chilled, I aerated, and pitched a big slug of Brett C and a starter of WLPP530 (Abbey Ale) and fermentation took off like crazy in my basement at 68*. Once the ferment dropped to about 80% expected attenuation, I moved to my garage, in the 90's to promote funky and bretty flavors. After a few weeks, I sampled, and found this beer to be very one dimensional, and not quite what I was looking for, so I decided to dry hop with Willamette.
