GNBF Brew Review - An Cat Dubh

The Great Nebraska Beer Festival was a wet and wonderful affair in the parking lot of Nebraska Brewing Company in Papillion, Nebraska, and featured many local and national breweries.  Over the next few days, I will be featuring different beers that I sampled at the festival, highlighting those that particularly stood out to me.  I don't have awards to give, but if I did, these beers would be the winners.  I will admit up front that many sour beers really were very interesting, and so several of these mini-reviews will be about some of the outstanding sour beers.

The first mini-review would be an award for the "Surprise of the Festival."  I generally don't find "chain brewery" beer to be particularly interesting, but Rock Bottom-Des Moines brewmaster Eric Sorensen has changed my mind with his An Cat Dubh, a sour/wild ale checking in at an easy drinking 4.75% alcohol.  It's a dry irish stout barrel aged three years that has two strains of brett yeast working it and then blended with fresh stout, turning it into a delicious concoction.  It is a slightly roasty, slightly chocolately, tart and floral beer; not overly sour but definitely different and worth a try!

Of course, brett beers are crazy difficult to deal with, as is explained in an article by MetroActive and by WYeast Labs.  In a brief discussion, John McDonald of Boulevard Brewery explained to me how difficult it is to control brett yeasts within a brewery; it's always a fear of brewers that the brett yeast strains will get out and damage other beers.  So it's quite an accomplishment for Rock Bottom Brewery.  Congratulations to the brewery for a fine, fine beer.  Cheers!
