The State Line. Since its earliest beginnings as a stopping-off point at the confluence of two mighty rivers, it has both shaped and defined our amazing city. It's in this spirit that we present the third annual limited edition Rieger’s Sporting Kansas City Whiskey, a signature blend of Straight Bourbon, Straight Rye & Light Corn Whiskeys with just a hint of Sherry - a marriage as unique as the two cities that share its name.
