From Rum Nation:

Appearance: Dark amber.

Nose: Dark, musty, very estery (fermented fruit, glue), with notes of cola, myrtle and bergamot tea.

Palate: Viscous sugarcane molasses, dark chocolate, coffee, dried raisins, and a slightly toasted and bitter background which hints at herbal notes (black tea and gentian root). Dark and sweet at the same time.

Finish: Endless interplay between the herbal bitterish character and the sugary sweetness. Ultimately sweet, almost syrupy and slightly winey, like vermouth.

Comment: A heavy Demerara, with its evident sugary sweetness, but also very dark, estery and aromatic.
