Rum is the most diverse spirit category. White (Plantation 3 Star, Bacardi) — Mojito, Daiquiri. Aged (Plantation 5 Year, Diplomático, Appleton 12) — Mai Tai, sipping. Demerara (Pusser's, El Dorado) — overproof base for tiki. Rhum Agricole (Clément, Rhum JM — French Caribbean, sugarcane juice not molasses) — Ti' Punch, Mai Tai. Blackstrap (Cruzan, Hamilton) — Jungle Bird, dark depth. Each works in different builds; never substitute blindly.
