Buffalo Trace Kosher Straight Rye is a collaboration with the Chicago Rabbinical Council (cRc). It is distilled from grains and aged in Kosher barrels for seven years. To meet Kosher requirements, the barrels are sold to a non-Jewish executive in a cRc-observed ceremony, though the whiskey is not Kosher for Passover. The bottling lines are cleaned to ensure no contact with non-Kosher spirits.
Easily the best of the three for me - a pleasant sipper that also wouldn’t disappear in a cocktail. Wouldn’t mind having this on my bar if I could only choose one.
