Chalky, inky, umami flavor. Slightly tart finish, a bit like Worcestershire sauce, which matches my previous experience with Ola Dubh. Woody but not actually very peaty.

Has a good spicy/stouty nose. Very spicy to taste, my reaction is almost like to an ipa, but it's clearly a different sort of herb

Clearly a sour from the scent. It tastes like a gin-spiced sour, which is interesting. I don't actually like gin, but I enjoy this.

The description mentions notes of Worchestershire sauce, among other weird things, and it's not wrong. There's a savory tang underneath an otherwise normal, pleasant & strong imperial stout flavor, which lingers afterwards. Really strange, but I think it's appealing. Maybe?
