A barely legal aquavit-style hooch with no redeeming qualities whatsoever. Total waste of money and time. It's not Floki, but it's not much better either. Just another cash-in on the bubbling whisky market.
Look at that average score (81 as I write this). It implies a perfectly solid whisky similar in quality to core range malts like Glenfiddich 15, Glenlivet 12, or the like. Now, get a glass of either one of those and a glass of Nidavellir, compare them, and then come tell me they're of equal quality, with a straight face. I dare you.
Sawdust, my favorite (not). Bland, with that spicy rye flour smell that seems to haunt these new distillery 3yos no matter which country they come from. It feels like a lot of cask enhancement was needed to give this thin distillate any kind of character, which isn't exactly surprising considering continuous distillation was involved, which also explains the lack of a stinging ethanol note in what is otherwise not really different from a flavored gin. Cheap dark bread, cheap liqueurs, cheap everything. It's supposed to have been partially matured in ex-Islay casks but I don't really notice any peat. Maybe the casks were from Bunnahabhain? ;)
Thin and sawdusty. A hastily finished aquavit indeed. Dirty, dusty herbs and rye flour, and a sweetness on top of them like that of hard candy drops.
Sweet, boozy, thin, and unfocused. The kind of stuff that could only sell at the peak of a whisky boom. I didn't finish my 2cl.
