From the brewery:

We love Mexico! not least because of the culinary gifts it has given to the world. Both chocolate and vanilla beans are indigenous to Mexico and nowhere on the planet celebrates the nuances of the chile (not chilli or chili) more than in its homeland. Our love for Mexican culture and food is the reason we made this rich, boozy imperial stout infused with vanilla beans, cocoa, cinnamon, chipotle and mulato chiles.

Sweet, smokey, hot, fruity, delicious. Buen provecho!
