Gustav Hossain-Endl of Shore Leave Restaurant Triumphs in Probitas White Blended Rum Daiquiri-Inspired Recipe Contest

Corona del Mar, CA (August 4, 2025) – Probitas, the award-winning multi-island white blended rum which has set a new gold standard for use in cocktails, crowned Gustav Hossain-Endl of Shore Leave restaurant in Boston, the grand prizewinner of its “Home & Away” drink recipe contest at Tales of the Cocktail in New Orleans last week. Gustav edged out five other finalists with his signature cocktail, the “H&E Frozen Daiquiri,” and will receive a seven-day trip to Barbados, including a Deluxe Pass to the annual Barbados Rum Experience.

The inaugural competition challenged bartenders to create a unique Daiquiri-inspired cocktail, blending “Home” (local) and “Away” (distant) flavors into one unforgettable cocktail – just like Probitas Rum, a fusion of rums from Barbados and Jamaica. Participants submitted a daiquiri-inspired cocktail recipe which included Probitas White Blended Rum and combined the contrasting themes and flavors derived from home (a familiar place such as where participants live, grew up or consider a “home place”) and away (somewhere new and different). Entries were judged on persuasiveness and effectiveness of capturing the Competition theme; quality of instructions for preparation of cocktail; originality and creativity; and “balance” of flavors in the cocktail. Gustav’s winning cocktail included: Probitas, Spiced Hazelnut Falernum, lime juice & zest, Jaggery, and Saline.

“Probitas has been my go-to rum for a daiquiri for a long time so when I created my drink, I wanted to add some of myself without losing the quality of the rum, or the essence of a daiquiri,” said Hossain-Endl. “In part, my inspiration was the daiquiri itself, its Cuban origins and its evolution. But my primary influence was my family; the union of two very different cultural heritages, meeting in the middle and creating something unique. This same spirit is very present in Probitas itself being a meeting of two different cultures of rum production. 

“The energy, creativity, and sincerity of the bartenders were thrilling,” said rum expert, award-winning distiller, and judge Maggie Campbell. “In my 20 years in the industry, I could not have dreamed up the innovative and delicious ideas the competitors had. From corn silk, to clay water, to cooling cumin notes in a blended daiquiri, I'll remember these Probitas creations forever.”

A version of Gustav’s daiquiri will be available at Shore Leave in Boston, a restaurant best known for Asian inspired dishes paired with an array of tiki cocktails.

About Probitas White Blended Rum

Probitas comes from two of the most iconic distilleries in two of the most respected islands in the Caribbean for rum making – Foursquare Rum Distillery in Barbados and Hampden Estate in Jamaica. This is the first time that a White Blended Rum has been made entirely in the Caribbean, from multiple islands and producers, with components selected by the rum makers themselves. Probitas is a blend of three distinct rums, blended by Master Distiller and Master Blender Richard Seale of Foursquare Rum Distillery in Barbados and marks the first time there has been a joint venture between

Caribbean distilleries to produce a blended rum. The components include Unaged Pot Still

Rum from Hampden Estate in Jamaica selected by Mr. Vivian Wisdom (Hampden’s Master Distiller at the time of blending), along with Unaged Coffey Still Rum and Two-year Aged Pot Still Rum from Foursquare Rum Distillery in Barbados, selected by Richard Seale. Probitas is distilled, matured, blended, and bottled in the Caribbean. No sugar, flavor, color, nor neutral/multi column spirit added.
