The Põhjala Öö Cassis was a really interesting flavor profile. Although the balance was fairly average, the overall beer experience was very good. The blackcurrant is prominent, so this isn't a beer you would have more than one of in a session.
Overall, I found the Põhjala Jõuluöö a very good beer. A satisfying example of an oak aged stout. I would love to see a release example at 10% ABV or above to see how far they could push the flavor profile.
