Lots of mint and menthol. Chocolate notes. Pleasant spice alongside it with some oak and barrel char. Quintessential, to me, Willet grape must/pomace/grappa and bubblegum also appear (that I get truckloads of in their wild and delightful 4-year rye). In bourbon form, a bit disjointed and not particularly impressive, but certainly drinkable and a quality spirit. A bit “off-kilter” from mainstream, sweet/vanilla bourbons, but that could be good or bad depending on your preferences or expectations. For the slightly adventurous.
