Putterho It's delicious (dropped in CA a few weeks ago) but not $400 delicious. My guess is it wins whiskey of the year because for the retail price it's one of the best pours out there. They could probably charge $99 and it would be well worth it.
Haven't tried the Willett x Blackened yet but hearing mixed reviews on that. This years Michter's Toasted Bourbon is just starting to drop and that one is always delicious (albeit still just way too low proof for my liking). If you have a chance to track down any Nulu toasted bourbons or rye's, I highly recommend them. Good Times is also doing some cool finishes. I've got a toasted bourbon that is finished in honey barrels for a few weeks/months. Smells like straight caramel. Palate leaves a little to be desired but it is tasty for sure!
