This may be it.  This may be your last chance to try the “original” American IPA on cask from Schlafly.

This Thursday, April 1st, starting at 6:30PM, a representative from the St. Louis Brewery will be tapping a cask of the American IPA and will be serving it at the Hair of the Dog Pub on Washington.

This beer will be available until they run out or the pub closes.  My guess is that the won’t have to worry about it not running out.
