The Golden Barnacle is a rum-forward tiki-style drink built on a foundation of warm baking spices. Grassy agricole and funky Jamaican pot still rum provide an aromatic base, while allspice dram and cinnamon deliver a pronounced spice character that borders on autumnal. Grapefruit and lime cut through with enough acidity to keep the honey-sweetened drink from becoming heavy, resulting in a complex sipper that drinks rich.
