The Castle & Key Kentucky Straight Rye Whiskey Finished in Extra Old Haitian Rhum Casks is a limited-edition expression from the distillery's highly acclaimed Experimental / Cask Finish Series. Produced at the historic Old Taylor Distillery grounds in Frankfort, Kentucky, this innovative small-batch release takes standard spicy American rye and marries it with the earthy, tropical sweetness of French-style Caribbean rhum barrels.
