The constant motion of the sea churns the whiskey, increasing its interaction with the wood of the barrel. Extreme weather ranging from the coldest of coldest to the warmest of temperatures hyper-ages the liquid in ways no rickhouse could. Jefferson’s Ocean Aged at Sea® Bourbon is Aged At The Mercy of The Sea. Experience a voyage yourself.
