This brand appears in a 1932 letter from Albert Blanton, directing that cases of O.F.C. bottled in 1919 be rebottled as Mirror Brook to update obsolete pre-Prohibition labeling. Newspapers from 1933 and 1934 advertise Mirror Brook as either a blended whiskey or a 16-year bonded whiskey. Blanton may have used Mirror Brook to package similarly unusual releases that did not match the flavor profile of the distillery’s flagship brands.
