Buffalo Trace Kosher Rye WhiskeyBuffalo Trace Kosher Rye Whiskey In partnership with the Chicago Rabbinical Council (cRc), Buffalo Trace Distillery produced this Rye Recipe Bourbon Whiskey. Made with the same high quality grains as Buffalo Trace Bourbon Whiskey, this Kosher spirit was aged in specifically designated Kosher barrels. In order to satisfy Passover requirements, these barrels were sold to a non Jewish executive in a ceremony witness by a representative from the cRc.
