This weekend, Weldwerks Brewing Co. is selling tickets for two brand new bottled versions of its popular Medianoche imperial stout.

The first version is Peanut Butter Cup Medianoche, an imperial stout aged in freshly-emptied barrels that previously held Breckenridge bourbon as well as freshly emptied barrels that previously held Woodford Reserve Double Oaked whiskey for between 16 and 24 months. The stout was then conditioned on peanut flour and more than 15 pounds per bbl of Reese’s peanut butter cups before being packaged in 22-ounce bottles and priced at $32 each.

In addition, Weldwerks will be releasing Bourbon Brandy Medianoche, an imperial stout that aged for 24 months in 2016 Woodford Reserve Master Collection barrels, which were former American oak brandy casks used to finish mature Woodford Reserve for over two years. While multiple versions of the Medianoche base stout have been aged in various brands and types of barrels over the years, this incarnation has been aged longer than any other release in Weldwerks’ history and is priced at $30 for each 22-ounce bottle.

According to Weldwerks, tickets will go be free and will be distributed via Eventbrite on Dec. 1. Each ticket will entitle the attendee to one bottle of either beer, and there will be a strict limit of two tickets for Peanut Butter Cup Medianoche and two tickets for Bourbon Brandy Medianoche per person. In addition, there will be no proxies allowed and customers will be able to pick up their bottles at the brewery between Dec. 7 and Dec. 16.
