The Commando Grog is a potent, heavily spiced tiki drink built on a foundation of dark and overproof rum. Warm baking spice notes from the allspice dram and falernum meet the nutty sweetness of orgeat, while grapefruit and lime provide enough citrus bite to keep the drink from tipping into cloying territory. It's a robust, aromatic sipper with considerable proof lurking beneath its tropical exterior.
