Allspice dram is a rum-based liqueur flavoured by steeping allspice (pimento) berries, giving it a warm, spicy character.
Warm and spicy, evoking cloves, cinnamon and nutmeg over a sweet, rum-inflected body.
Poured in dashes or a barspoon, it works as an aromatic spice accent rather than a base; being syrupy, viscous and intensely flavoured, it is dosed in small amounts against the base spirit, though it can also carry a drink as a defining flavour measure.
As a small aromatic accent, allspice bitters or a pinch of ground allspice with added sweetener approximates it; as a defining flavour measure it is effectively not substitutable, since only an allspice-derived source reproduces the pimento aroma. A clove-heavy mixed spice partly stands in through shared eugenol, but loses the nutmeg and cinnamon nuance.
Allspice dram is a sweetened, spirituous liqueur used in appreciable measure; allspice or aromatic bitters are high-strength, unsweetened, heavily concentrated preparations added only in dashes. Some producers make both a dram and a bitters, which adds to the confusion.
Producers macerate the dried unripe berries of Pimenta dioica in a rum base, drawing their spice oils into a sweetened spirit. The berry's dominant aromatic compound is eugenol, the same volatile oil that gives cloves their scent.
The liqueur is Jamaican in origin, tied to the West Indian pimento tree, and pimento dram has been an article of commerce since the 1850s.
