I have a bottle of PVW15 open and there is an off taste that I don't believe belongs here. It's what some of you call earthy, but to me it tastes like dirty, moldy cardboard. It tastes the way your grandmothers cellar smelled. This taste is very strong, probably the second most prominent in the glass. It's weaker in the nose, but after tasting it, that off smell is present. Honestly, this bottle is terrible. I have been looking forward to trying this pour for the longest time, and it's extremely disappointing.
I've tasted this once before, on a bottle of VSOF which is easily the worst whiskey I have ever tasted.
It looks like a lot of money down the drain at this point. I bought two bottles and this one is so terrible I am considering opening the second to see if it's just a bad bottle.
