At 35% ABV and sweeter than your grandmother (not mine, yours) this is a liqueur and not a whiskey but is getting some traction in market the way Fireball did. The nose has ballpark crackerjacks, cough syrup, the inside of a candy store. The taste is sweet with more syrup and marshmallow notes. The peanut butter shows up a bit late but strong in finish along with barley sugar and finally some grainy alcohol notes.
This is not whiskey. You may like it.
