From the Jefferson’s website:
Thomas Jefferson, our third president, was a wine aficionado. He was America’s first ambassador to France and, while there, fell in love with the finest wines of Bordeaux. Once of his favorites was the Chateau Pichon Baron, an exceptional red wine.
Based on our experience finishing Jefferson’s in creative ways and in various types of casks, we felt strongly that the Pichon Baron wine and the toasted staves of the French oak wine casks would complement our well age, complex Kentucky Straight Bourbon whiskey.
After hand selecting a limited number of Pichon Baron barrels, refilling them with Jefferson’s Reserve bourbon and extra aging them in our proprietary “hot box” environment, we have created a one-of-a-kind whiskey that combines the robust flavors of the Bordeaux, the wood notes of both American and French oak and the grain of a premium bourbon in a delicious, complex and balanced final product.
