At first I got caramelized banana on the nose. I took a sip and got some light grassy notes, a little citrus or lemongrass, and a smooth, mild baking spice. After the first sip, my wife and I agreed the scent changed - bubble gum. The cheap Double Bubble pieces we used to get for Halloween. Second sip, some woody caramelized barrel char flavors with a slightly herbal note. 3rd nose was empty marshmallow bag. Not marshmallow. Empty marshamallow bag. Weird, huh? It's that chalky, powdered sugary, light sweetness. 3rd sip... Still grassy, woody, barrel char type flavors. It gets a more oily mouth feel with each sip. Man... This is COMPLEX. Love this bourbon!
