This is the Buffalo Trace Kosher "Wheated" Bourbon
"Buffalo Trace Distillery produced this Wheat Recipe Bourbon in a partnership with the Chicago Rabbinical Council (cRc). Made with the same high quality grains as W.L. Weller 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 witnessed by a representative from the cRc. After aging for seven years, this Wheat Recipe Bourbon was bottled at 94 proof after ensuring the bottling lines were cleaned beforehand and that no contact was made with non-Kosher spirits. Released after Passover each year, this Wheat Recipe Bourbon stands alone, a tribute to the legacy of America’s oldest continually-operating distillery."
