Next month, Denver beer aficionados will get their chance to try the beers at Bierstadt Lagerhaus, the new project for craft brewers Ashleigh Carter and Bill Eye, both former brewers at Dry Dock and Prost. The River North brewery will hold a “Countdown to Lager Party” at 11 a.m. Aug. 13, inside the Rackhouse pub — their taproom, as well as the taproom for C Squared Ciders — at 2875 Blake St., according to a release.
