From the Oxford Bottled Beer Database:
This is Young's renowned bottled stout, made using a significant proportion of chocolate malt. It is also something of a style classic. The beer is a dense brown-black colour with a creamy beige, thick and bubbly head that lasts well. On the nose there is powdery chocolate and rich, yet dry malt, along with a slightly sour tinge and a hint of bread. The palate is amazingly smooth and creamy, although quite lively, with lots of bitter, dark chocolate and some smokier malt flavours present. It manages to remain fairly dry throughout - the finish is perhaps slightly sweet, but leads into a bitter malt and chocolate aftertaste, which avoids being cloying. Overall, this is a remarkably rich, full-flavoured and well-balanced complex stout. Its smooth and creamy mouthfeel also makes it extremely drinkable.
Try it with a Padron 1964 or 1926. Both are great pairings.
