When I first wrote about Koval Distillery, I asked Robert Birnecker and Sonat Birnecker Hart if they’d ever consider aging any of their pure organic white whiskeys. A year and a half ago the couple had yet to release their first bottles, and the idea of putting up precious spirit in barrels for months and months when bills needed to be paid seemed like a dream. Even now that they’ve hired a second distiller, a publicist, and have added many more bottles to their profile, it still seems incredible. And yet next week they’ll be releasing four brown liquors that have been slowly aging in new charred oak barrels in the Ravenswood distillery over the last year.
