HOW RUM IS CREATED
at GrRUM Distillery

FROM SUGARCANE,
CAREFUL DISTILLATE SELECTION,
TO A UNIQUE CHARACTER
The foundation of GrRUM Distillery rums is carefully selected sugarcane and high-quality rum ingredients, further crafted under our own expert supervision.

THE JOURNEY TO THE CZECH REPUBLIC
Selected ingredients and distillates are transported to the Czech Republic, where the entire process of production, distillation, aging, and further rum craftsmanship continues.
It is here that we combine Caribbean character with Czech craftsmanship, our own approach, and attention to detail.
WATER...
The quality of rum does not begin with distillation...
It begins with water.
For the production of our rums, we use pure mountain water, which influences the smoothness, balance, and final character of every edition.
It is the combination of Caribbean distillates and Czech mountain water that creates the distinctive profile of GrRUM Distillery.


FERMENTATION & DISTILLATION
Every fermentation and distillation process is carried out with a focus on purity, smoothness, and the final character of the rum.
Through multi-stage distillation in a column still and our own know-how, we create a distillate with exceptional smoothness and a clean profile.
The result is a balanced rum suitable both for long-term cask aging and for premium drinks and modern cocktail culture.
The smoothness of the distillate is one of the defining signatures of the GrRUM Distillery style.
AGING & CASK WORK
Selected rums are then placed into oak casks, where they continue to develop their character, depth, and aroma.
We use, for example, French oak casks that previously held Bordeaux red wines, giving the rum smoothness, structure, and a unique flavor profile.
Some of the rums are left to rest long-term in our cellar, where they continue maturing under our supervision and gradually develop their own distinctive character.


CUSTOM RUMS & LIMITED EDITIONS
Part of our production is bottled as our own white rums and overproof editions with higher alcohol content.
Other distillates are used for creating limited series, private blends, and signature editions produced in small batches with an emphasis on character and originality.
Each edition is the result of time, experience, and individual craftsmanship at GrRUM Distillery.

CUSTOM RECIPES
& RUM SPECIALTIES
Our signature products are then created from our own rum bases — herbal rums, walnut specialties, and other original recipes under the GrRUM brand.
Each recipe is crafted with a focus on balance, smoothness, and preserving the character of the rum itself.

We do not believe in the fastest way.
We believe in the right one.
GrRUM Distillery
Czech Craftsmanship, Caribbean Character.
Pure Mountain Water
For our rums, we use crystal-clear mountain water, which is a key part of the final flavor profile. It gives the rum smoothness, roundness, and a refined finish. It is not just a technical part of production — it forms an essential part of the character of every bottle.
Thanks to it, our rums are exceptionally drinkable, balanced, and smooth, while still preserving their distinctive rum character.
