This happened at a bar in Des Moines last time this beer came out. Tapped a keg of KBS and were selling pints of it for $5.
I don't mean to be skeptical but, on 4/1/2016, the Draught House on Mills Civic in West Des Moines had a keg of KBS. We lucked into being there and had a long conversation with the General Manager who didn't have a clue about the KBS phenomenon. He was stunned that my wife and I were so thrilled to be paying $9 for a full pint (I'd pay that or more for a snifter). He told us that the keg cost approximately $1,000. He felt that the price would "scare" away customers but he was constrained due to the keg cost. If you do the math, with no waste (they were not allowing "tastes"), the bar would make about $116 on the keg. I told him that we appreciated the price but that he was underpricing it. For full pints (16 oz), he should have been charging at least $12, if not more. In actuality, he should have been serving it in 8 oz snifters for $9. He would have not only doubled his revenue but that is how a KBS or other high-gravity, barrel aged Stout should be served.
If you found a bar selling it at $5/pint, that bar would have lost about 35% on their purchase of the keg.
The Des Moines metro received a grand total of 6 kegs of it last year. I have a hard time believing that any of those establishments didn't understand that they were receiving a limited release, that they were paying a premium price and priced the pours so that it would take a hit financially.
That written, if you find an place like that - please post it immediately. I'll throw my growlers in the car and take advantage. If they are willing to sell $5 pints, perhaps they'd be naive enough to sell growlers of it.
And, yes, I already know that I'm a stout geek/dork/snob. One must recognize one's faults.
Speaking of stouts ... Madhouse is having its Carpe Diem 2017 release on 2/17. Great local stout. Could be the best. Better than Milkman Stout, Sir Moch A Lot and, IMO, better than Jesus On A Forklift (although the latter is really good).
