National Lager Day is December 10, but really we celebrate the lager every day here at 22 Northmen Brewing Co. Our lagers are inspired by the brisk latitude and rooted in tradition, and we craft them with precision and nuance using time-honored techniques.22 Northmen Head Brewer, Keith Hefley, is a long-time lager lover. Early on in his brewing days, beers with aggressive flavor profiles, especially IPAs, were big on the scene. After spending years refining his techniques, Hefley started getting more and more into lagers.
