Join us on Sunday, August 27th, for a special brewery-only release of N. 46 in our Barrel-Aged Series, named Promiscuus. This 8.6% sour ale has been aged in Madeira and port barrels resulting in a rich and decadent sour that is slightly sweet and delivers on tartness. Starting promptly at 1:00pm, Promiscuus will be available for purchase ($12 per bottle) at the Boulder brewery.
