our team

Without pretention or illusions, we look beyond tradition to create spirits like no other

– complex, distinctive, and eminently drinkable.

Ruben Maduro


From an early age I learned that life tastes better when you work with the best available ingredients…With a strong passion for rum, one day I looked around and was disappointed to see that many rums often contain artificial flavouring and taste of cheap vanilla.

It’s what ignited a simple but bold mission to introduce a new way how rum is made. By re-distilling and infusing rums from across the World with real botanicals. It’s our mission to create rums that are better tasting and better for the World.
