sailor's swizzle

1 1/2 oz Bacardi Carto Oro Rum (Old Ipswich/Turkey Shore White Cap)
2/3 oz Ruby Port (Taylor Fladgate)
3/4 oz Lime Juice
1/2 oz 2:1 Simple Syrup (3/4 oz 1:1 Simple)
1/8 oz Allspice Dram (St. Elizabeth)

Build in a Collins glass, fill with crushed ice, and swizzle to mix and chill. Garnish with a few dashes of Angostura Bitters and lime zest strings (spent half lime shell and mint).
Two Thursdays ago, I was in the mood for something a bit more tropical, so I remembered that I had spotted an interesting yet classic-feeling Swizzle on Difford'sGuide a few weeks ago. The drink was the Sailor's Swizzle crafted by Erik Lorincz of the American Bar in London circa 2012. Once built, it offered a mint, allspice, clove, and lime oil aroma. On the sip, crisp lime was balanced by sweet grape notes, and the swallow shared rum and allspice on the swallow that later gained Angostura's clove and cinnamon as the garnish integrated into the drink.
