Huge. Extraordinary complexity. Nutty. Stale peanut brittle. Fresh, dry roasted hazelnuts, almonds, pecans, and Brazils. Raisins, figs, prunes, chocolate, vanilla, dates, rye, barley, barrel char. Perfect balance of dry vs sweet, dark red grapes, sour cherries and artificial cherries, fresh and dried fruits, rich oaky butterscotch from the 20 y.o. sherry, which also imparts a tannic, drying mouth-feel. Mouthwatering effect. Plums, red and black liquorice. Sherry up front met with bourbon and more sherry in the middle and somewhat leaning towards bourbon but with more sherry in the end. Sherry and barrel spice lingers on the aftertaste. The casks and barrels were expertly married, it's neither sherry nor bourbon dominant overall, it's very well integrated, and not at all over-oaked. There's a lot of different notes very close together, yet all are discernable. Medium entry, long middle, and a medium-long finish. High quality, very satisfying, and certainly unique. A new experience. A huge whisky that is sure to get a reaction one way or another! Considering the cost of 20 y.o. sherry casks...at $147.95, this is a steal. I'd pay up to $225 for a rare experience like this. Don't approach it as a bourbon or a sherried whisky...embrace it as something new and unique, and enjoy the wild ride! Note: review edited...the somewhat seemingly conflicted notes that didn't seem to fully harmonize at first, have come together wonderfully now. Drinking very nice 4 months in. Give it time, you'll be rewarded.
