This is good, but it's pretty "rich" with the port, cacao liqueur, AND Galliano Espresso Coffee liqueur... I'm wondering if this would be a good one for Mr Black since it's supposed to be drier, so it might bring more balance?
Overall, I like this, but it's pretty sweet and the Douglas-Fir note is fairly prominent, so it can be a tricky "ingredient" to mix with... Citrus juice seems to be a (not surprisingly) common way to try to balance this in a cocktail/"mocktail".
