About Us

Cocktail Bar Hospitality

Three bartenders, one shared vision. Our story began over a decade ago, behind the same Brussels bar. After honing our skills in some of the world’s finest cocktail bars, we reunited with a single goal: to create a space that reflects our passion for quality, creativity, and connection.

At The Modern Alchemist, we craft cocktails with precision and heart. Specializing in rum and seasonal creations, we use only the finest spirits and fresh, mostly organic ingredients. Our cozy, inviting atmosphere is designed for moments that linger—where every drink is an experience, and every visit feels like coming home.

Driven by curiosity and a relentless pursuit of excellence, we’re always exploring new flavors, techniques, and ways to make your time with us unforgettable. Because for us, a great cocktail is more than a drink—it’s a memory in the making.!

With a discreet industrial look, this chic bar has been making rum, for some time now, one of the most exciting spirits. The supply of rums increased from 70 to 120 references last year, with a preference for small artisanal distilleries. Anyone wishing to acquire knowledge in this field is knocking on the right door. In this context, the bar even applies the break-even bottle’s principle for exclusives bottles, which allows you to taste a special rum at a cost price. “Sharing is caring”!

Gault&Millau L’expert Gourmand

The first time we came, Christopher was the one who welcomed us at the Modern Alchemist. The bar had just opened and he was still finishing to set up, but he gave us a warm welcome nonetheless. Located a few meters away from Place Van Meenen since December 2018, the opening of The Modern Alchemist has already got many people talking. And we’re not surprised. With his two business partners, Sébastien and Benjamin, they found right the recipe. Specialized in rums, they offer over 70 references to their customers. But those are not just any rums: all of them have been made according to the traditional method, and contain no additives. (…)

Brussels’ Kitchen The Guide to food with style

The Modern Alchemist is the place to be for lovers of rum (more than 200 references available) and homemade seasonal cocktails. Christopher Ducat, Benjamin Deniel and Sébastien Bourdain’s, happy trio of barmen, earned their stripes in the best cocktail bars in the capital. It’s no wonder that The Modern Alchemist has become a real household name.

Situé à Saint-Gilles, ce bar à cocktail de haute mixologie n’a pas souhaité surfer sur la vague du gin. Dès lors, The Modern Alchemist a lancé son propre concept : créer des cocktails à base de rhum. Des dégustations de rhums sont donc à la carte permettant à ceux qui n’y connaissent rien de s’initier aux plaisirs de cette eau-de-vie si particulière pour accommoder son palais. The Modern Alchemist propose par exemple l’Elixir d’Eustache, un mélange de rhums maison, de Chartreuse verte, de cordial cold brew et de jus de citron vert. Á tester au risque d’adorer et d’en reprendre un deuxième.
