This unaged Overproof rum has a strong and fruity flavour profile. The slow fermentation giving rise to its powerful fruity and funky notes makes it ideal for more complex cocktails and mixed drinks.

Momentarily we are on to our third batch of Rummieclub Overproof. A funky, exciting rum as you can expect from us. In Judith’s words; “the perfect marriage of the rummy flavours of batch 1 with the funk of batch number 2”. As all of our Overproofs this batch is build up with our base marque, our dunder marque (the leftovers from the previous distillation) and a wild yeast rum. In this case with wild yeasts from the pear blossoms from our garden. Be quick as this batch is quite small and only contains 104 bottles. The result is a fruity, a little funky unaged rum full of character at 58% abv. All marques are made with organic molasses from Paraguay, fermented for a week or more, distilled in our iStill 500, without any filtration or additives.

Overproof rum is category of rum with a higher percentage of alcohol than regular rum. There are several stories on why it is called overproof and what exactly overproof means. Gun Powderproof, British overproof and American overproof are all different in ABV, but fall between 50% and 58%. Next to that you have some unaged Jamaican overproof rums which are mostly around 63% abv.

Rummieclub Overproof rum has an alcohol percentage of 58%. We tried several different ABV’s and we liked the 58% best, it opens up the rum just enough to reveal its base flavour profile. At higher ABV’s it is difficult to smell what you are actually going to taste when you try the rum.

Every edition of Rummieclub rum has an artwork on the frontlabel which is made by a different local (graffiti) artist. The artwork on this label is made by Munir de Vries, a local visual artist and muralist. The label represents animals getting drunk from overripe fruits.
