Built in 1881, this graceful whiskey aging warehouse is a fine example of Rick Construction. Its basic structure is built of massive wooden beams that bear the entire weight of the 24,000 barrels residing within. The foundation consists of Kentucky River Marble quarried from the Kentucky River a short distance away. The 18-inch-thick brick walls allow warehousemen to control the temperature inside. The shuttered windows are opened in summer and closed in winter so a perfect temperature balance is maintained and the barrels are allowed to age year-round. When the windows are open and the breeze is just right, the aroma of bourbon, known as the Angel's Share, can be smelled.
