As to the statement that JD Black is mingled for flavor check again, it is loaded into the top floors so the aging house does not FALL down. You can actually feel it sway as a slot is loaded. The only thing you mingle Jack withis a glass, air and your lips. Bet you use ice too so you can "Mingle flavors"
