KBS is made form a blend of different bourbon barrels. Also, they sample each barrel of KBS while before bottling for QC and blend the barrels they think will be best for the flavor they want. There is more variability between years with KBS than with non-barrel beers due to the variability of the barrels. (Although the same kind of thing can happen with hops, I suppose.)
I found this year's to be good, but it's not as strong as last year's, and I kind of like the more boozy flavor of last year's. The KBS clone my club made was even more boozy than any KBS I have had. Even after a year in the barrel it's still hot. I've got nearly 10 gallons worth of bottles aging. (Reminds me the wife wants them out of the living room. Should try and move them tonight. Not sure where yet.)
