A couple weeks back, a friend of mine inquired about supplying some homebrew for their non-profit's (Hope Through Health) charity event. The event is called "Cask for a Cause"(details) and will be held at Local Habit at 5:30 on Thursday, May 23rd.
I asked her what type of beer she would like me to brew for the event and the first response was an IPA. I immediately responded that its not really my style plus, there would be about 5 world class examples on tap at the same time. I knew that the deadline was approaching, so I wasn't sure if I'd be able to brew a beer in time so I offered the keg of my 2011 Oud Bruin. I actually hadn't tasted it in a while (since before I moved), so I took a sample of it that night. The beer had a great tart cherry nose and quite a bit of sourness (even a bit acetic since it was sloshed around during moving). It was good, but I knew it would need to be blended. I initially thought it would be too sour for the general public and secondly it was kinda dry and thin for my liking. That lead me to want to brew a blending beer.I thought the Old Ale style would be a great beer to blend as they have some of the dark fruit flavors. Plus I like to make them on the sweeter side, which would give a nice sweet-sour balance for the masses. In addition, I can make a lower gravity Old Ale in about 2 weeks and it can still have some nice complexity to add to the blend.

To figure out the final blend I took the beers (Old Ale, Oud Bruin and my Imperial Stout). I helped guide the tasting and it was unanimous that everyone like the sour beer at its current state. Then I suggested a splash of the Imperial Stout because it worked so well for my Oud Bruin in the 1st Rd of NHC. All agreed that the Imperial Stout really improved the beer. So much for the Old Ale I brewed, but it makes a great base beer for a sour beer and I have some East Coast Yeast Bug Country on its way. And I'm thinking the other half will get some oak and black treacle (and stay clean).
If anyone has this Thursday free, please come try some free sour beer and support a good cause. I'll be there all night, but not sure how long the beer will last.
