Blanton's Empty Bourbon Whiskey Bottle 750ml With Letter "A" Cork Stopper The tiny horse and jockey on the bottle stoppers are now a recognized trademark of Blanton's Single Barrel Bourbon. The rich heritage and tradition of horses in Kentucky parallel that of bourbon. They have produced a collectors edition set of eight different stoppers, featuring a horse and jockey in different strides and poses. Each stopper is marked with a single letter that spells Blanton's when the set has been completed.
