Proserbräu

Steve, DeAunn's private teacher and a member of the orchestra here in SLC, has been a great friend to us in so many ways over the last three years. He's also one of the beer geekiest folks we know around here; we've enjoyed a number of get-togethers at his family's home where we shared new, interesting bottles with each other. Steve has a particular affinity for Belgians, so as we came to the end of our terminal degrees, nothing seemed so appropriate as brewing one for him.

Considering his favouring of beers such as Gulden Draak and Piraat, we aimed at crafting a Belgian strong. Vienna is my current go-to grain, as I'm working my way through a bag of Weyermann Organic Vienna; we augmented it with a bit of oats to add mouthfeel to what would be a fairly dry beer. A good dose of turbinado in primary increased dryness and colour, bringing it an amber hue. I've used the Duvel yeast strain on Belgian strongs in the past, but haven't cared as much for the "sharp" character it can bring. I was very happy, however, with the results I had with Belgian Abbey II in my Mad Elf clone a few years ago; in my aged quasi-side-by-side tasting, I actually preferred the rounded alcohol and more pronounced cherry presence of my version to Troeg's original.

My friend Brian came over to assist with part of brewday, including the ever-popular fermenter transfer/filtering out of hops. With his help, things went particularly smoothly. This was a small batch, and just about all of it went to its intended recipient; I only kept a six pack. I've had one so far; the yeast is even more muted than I'd intended, but it's still pleasant. Next time I'd probably push it to higher temps faster to try to increase ester production. So far it's hiding its alcohol very well; it's almost too easy drinking, and could cause some trouble if one weren't paying attention to consumption rate. Steve was really happy with our gift; DeAunn and I were pleased to be able to do something like this for someone who's done so much for us.
