Why it works
Dark chocolate can make dry table wine taste thin, sour, or bitter. Port-style fortified red works here because its sweetness, power, and dark-fruit depth stand up to blue cheese, chocolate, nuts, and intense dessert flavors. That makes the match feel deliberate: making sure the wine has enough sweetness for the dessert, staying in the same weight class as the dish, with the wine refreshing the next bite rather than stealing the spotlight.
