Cocktail Bar & Rum Bar

About Us
Cocktail Bar Hospitality.
The Modern Alchemist is born from the never-ending quality research of 3 passionate bartenders.
We became friends more than 10 years ago, working and learning our craft behind the same bar in Brussels. We then went our separate ways in renowned cocktail bars. After a couple of years, the same mindset regarding the service industry and the urge to create our own place brought us back together. Nevertheless, striving to deliver the best experience possible took us 3 more years to refine and shape the concept.
The result is a craft cocktail bar in Brussels, with quality service, a cozy atmosphere, comfortable seatings, and drinks made with love. Mainly focused on cocktails and rums, we only use the highest quality spirits and organic fresh ingredients on our seasonal menus.
We are always looking for new products and techniques; we are constantly trying to improve our skills and enhance the quality of time you spend with us in our cocktail bar!

Our Offer
Perfect drinks for everyone, everywhere, at any time.
Our main activity is tending our cocktail bar in the heart of St-Gilles, Brussels, where we use the finest and, wherever possible, local, fresh and seasonal products. But The Modern Alchemist has also an online shop! On our webshop you will find high-quality and authentic spirits choosen by our team.
As rum lovers, we mainly focus on this incredible spirit and even make our very own co-bottling. Still, we offer a wide range of other liquors such as Whiskies, Mezcals, and many more. Sellings spirits that we love weren’t enough, therefore we create a range of ready-to-drink bottled cocktails to enjoy a perfectly crafted drink, like in our bar, but in the coziness of your home.
We provide you pro and consumers Masterclass. We think spirits education is essential, as well as industry-related consulting for hospitality businesses who want to grow.(more info coming soon!)
