About

The Black Seal Manhattan is Gosling's house version of a rum Manhattan: two ounces of Black Seal black rum, three-quarters of an ounce of sweet vermouth and a heavy four dashes of Angostura bitters, stirred, strained into a coupe and garnished with a Toschi cherry. It is darker and richer than a whiskey Manhattan, with molasses where the rye spice would be, and the generous bitters give it a dry, aromatic finish that keeps the rum's sweetness in line. If you have ever wondered whether black rum can be a serious stirred-cocktail spirit, this is the drink that answers yes.

What Is a Black Seal Manhattan?

It is a straightforward Manhattan substitution: rum for whiskey, everything else in place. The proportions on Gosling's recipe page are slightly drier than the classic two-to-one, and the four dashes of bitters, double the usual, are the signature. The garnish is a Toschi cherry, the Italian amarena-style cherry in dark syrup that has become a bartender favorite; a Luxardo or brandied cherry works just as well. Served up in a chilled coupe, it is about as strong as a stirred drink gets, and it should be sipped slowly.

Origin and History

The Manhattan was born in New York in the 1870s or 1880s, and rum versions appeared almost immediately, because rum was as much a fixture of American bars as whiskey until Prohibition. Gosling's, distilling in Bermuda since 1806, blends its Black Seal from aged rums to a dark, molasses-forward profile that has anchored the Dark 'n' Stormy for a century. The Black Seal Manhattan is the company's argument that the same rum belongs in a coupe, and it sits within a broader revival of rum Manhattans in craft bars, alongside variations like the Black Rumhattan on Difford's Guide and the amaro-based Black Manhattan.

Flavor Profile and What to Expect

The nose is clove, cinnamon and cherry from the bitters. The first sip is molasses and burnt sugar from the rum, immediately balanced by the vermouth's herbal sweetness and the bitters' spice. The finish is long, warm and dry, with a lingering note of dark fruit. Compared with a rye Manhattan it is rounder and less peppery; compared with a Rum Old Fashioned it is softer and more aromatic. The extra bitters make it noticeably drier than most rum Manhattans, which is why it works even with a sweeter rum. It sits comfortably beside a Rob Roy or a Boulevardier on a winter menu.

Choosing the Rum and Vermouth

Black Seal is the intended rum and its balance of molasses and oak is what the recipe was built around. Cruzan Black Strap makes a much heavier, more savory drink; cut it with an aged Jamaican rum for balance. Martini Rosso is specified, but a richer Italian vermouth such as Carpano Antica or Cocchi di Torino adds vanilla and depth. Keep vermouth refrigerated once opened. Our rum cocktail guide covers the rum styles.

The Cherry

A good cherry matters in a drink this spare. Toschi, Luxardo and Fabbri amarena cherries all bring dark, slightly bitter fruit. Avoid bright red maraschinos; their syrup fights the bitters.

Popular Variations

Use half sweet and half dry vermouth for a Perfect Black Seal Manhattan. Swap the vermouth for Averna or Amaro Montenegro to move toward a Black Manhattan. Add a quarter ounce of falernum for a tiki-tinged version reminiscent of the Royal Bermuda Yacht Club. Serve it on a large rock for a slower, more mellow drink. Express an orange peel over the top for extra aroma. Rinse the glass with absinthe for a rum Sazerac feel. Difford's Guide's Black Rumhattan is a lighter-bittered version worth comparing side by side.

How to Serve It

Stir, never shake, and stir long enough to get proper dilution; this is a strong drink and it needs the water. Strain into a well-chilled coupe or Nick and Nora and drop in the cherry. Our ice guide explains why clear, dense ice makes better stirred drinks.

Food Pairings

It pairs with dark chocolate, pecan pie, aged cheddar, roasted nuts, a good steak and a cigar. It is a natural end to a heavy dinner.

Batching for a Party

For eight drinks, combine 16 ounces of black rum, 6 ounces of sweet vermouth, 32 dashes of Angostura and 4 ounces of water in a bottle and store it in the freezer. Pour directly into chilled coupes and add a cherry to each. The water stands in for stirring dilution, and the batch keeps for weeks, which makes this an easy signature drink for a holiday dinner or a winter cocktail party.

Why Four Dashes of Bitters

Most Manhattans call for two dashes, but black rum is sweeter and rounder than rye, and the extra bitters restore the dry, spiced edge that makes a Manhattan a Manhattan. If your rum is on the lighter side, three dashes may be enough; if you are using blackstrap, four is the minimum.

When to Drink It

This is a cold-weather, after-dinner drink for fireside evenings, holiday dinners and quiet nights. It belongs on any fall or winter menu. Browse more stirred classics in our drink categories.
