Autumn Ale

When the farmers start harvesting beans and corn around here, my allergies flare up. I have this constant tickle in my throat and I am constantly looking for the perfect medicine to sooth it. Currently I am trying this seasonal offering from Breckenridge. It's not the best I've had from there. It is dark and fruity as promised, but there is something tart here that makes me wonder: Was there some infection in this batch? Or are they intentionally trying to get in the fad of sour beers? For the moment, my ailment is cured.
