This is expensive: 10€ for a 0,33 l bottle. It is also a very strong beer at 10% abv. And it is a strange beer in being a sour imperial stout - all other sour beers I have had have been light colored. I am sure other sour porters or stouts are made. And if they are half as good as this one, I really want to try them.
It is slightly roasted as expected from an imperial stout, yet a sour fruitiness verging on the citric and floral is the most prominent aroma. For a beer that is 10% abv this is dangerously drinkable. No doubt the sourness coupled with quite heavy hops (68 EBU) makes this so light on its feet. Bracing. And pretty awesome, so I'm almost tempted to say that even at 10€ it is worth the price except I don't want to give Alko any ideas.
