Yes, I realize that it's been almost two months since I last posted. Around that time, there were questions as to our company's viability and things were very tenuous. Without getting into the details, I will just say that things are back on track at work and I've been very busy the last 6 weeks.
First, the kolsch. Things went very well with this brew, and it finished nicely at just under 4% ABV. I had a good amount of lagering time on it, in addition to getting my whirlpooling technique down to prevent excessive trub in the fermenter, so it's cleared up nicely. The carbonation could be a bit higher, but it'll suffice for now. The first keg is almost empty and I've been using a carbonation stone on the second, so we'll see how that one turns out.
Memorial Day weekend was brew day for my Bell's Oberon clone, which has been dubbed "Mikeron" by some, and in honor of those fallen, "MemoriAle" by me. I did a side-by-side tasting (early on, I might add) and it was pretty darn close. The color turned out a bit more orange than the commercial (mine is on the right), and my wife thought (again, early on) that mine was a bit grainy, but over the 4th of July weekend, we attended a barbeque in Carbondale and brought some along. Those wo sampled it remarked that mine was actually better than the commercial version. That could have just been kind words, or they could have been the truth. Either way, I think it turned out pretty damn well, and I am looking to make this a regular brew.
A nice feature of this event was the Replicale, where a dozen different members of the ICBG created their own version of one style beer. This year's was the Belgian-style wit, one of my wife's favorites (she LOVES Hoegaarden), and while they were all very similar, there were distinctions between them. I thought this was a great introduction to the subtle differences between beers of the same style, and really made the differences noticable. We were also able to join IMBIBE (I'm a Big Illinois Beer Enthusiast) as charter members. In all, it was a great event, low-key, but worthwhile and pretty well organized.
