Gosling's is the most famous rum brand from Bermuda a British Overseas Territory in the North Atlantic, geographically outside the conventional Caribbean rum zone. The Gosling family began importing rum to Bermuda in 1806; Gosling's Black Seal dark rum, the defining product, is a blend of aged Caribbean rums with a deep molasses character and high sweetness the base of the Dark 'n' Stormy cocktail, which the Gosling family has trademarked as requiring Gosling's Black Seal.

Gosling's Black Seal is one of the most recognisable dark-rum brands in the on-premise sector: the bottle's wax seal, the intense molasses character, and the Dark 'n' Stormy brand association make it immediately recognisable to hospitality buyers. For programmes building a classic dark rum cocktail service or a rum-by-the-glass range that includes the sweet/dark tier, Gosling's provides the Bermuda-origin benchmark for this style a category anchor rather than an artisan discovery, suited to volume cocktail service.
