C.S.B. = Crotch Sniffing Bastard or one of the best beer names I've encountered so far on this adventure.
C.S.B. is brewed by Laughing Dog Brewing out of Idaho. The name of the beer comes from the brewery dog's over zealous and highly personal greeting. Having known a few crotch sniffing canines in my day, I can easily see how one gets from friendly dog name to crotch sniffing bastard.
It pours a deep amber color with a full tan head. It smells mildly hoppy with some malt notes. It's everything one would expect from an ESB (extra special bitter). Just a touch of bitter but overall well balanced. A nice toasty malt flavor. This one has low carbonation and is very smooth. I like it!
