People still view Willett as relatively scarce, especially some of the bourbons, but hiding in plain sight is Old Bardstown estate, a 4-5 year bottling of Willett Estate bourbon bottled at 101 proof. Peanut butter, vanilla, and maple on the nose. On the palate, a rich, chewy, biscuit and orange marmalade note persist. Almost the PERFECT bourbon for an Old Fashioned.
