A thoughtful riff on the tiki classic, this Navy Grog balances a trio of rums—grassy white, aged Jamaican, and rich Demerara—against bright acid-adjusted pineapple and warm allspice. The result is layered and complex, with tropical fruit giving way to baking spice and molasses depth, while bitters and saline sharpen the edges. It drinks with the heft of a proper grog but maintains a refined, measured quality.
