A key stage in the distilling of spirits is dilution, whereby purified water is used to reduce the strength of the rum after barrel-aging. After the process of distillation and maturation, the rum’s ABV strength is too high for bottling and must be diluted using purified water.

The benefit of pure, demineralised water in dilution is that, the purer the water, the less impact it has on the meticulously crafted taste and appearance of the distilled spirit itself. It is important that the water used simply reduces the spirit to bottling strength whilst not effecting the quality, making water filtration one of the most important aspects of distilling high-quality rum.

To remove the risk of waste product, salts and ions need to be completely removed from source water. To achieve this, particle and organics filtration prepares water for our reverse osmosis system. Deionisation resin is then used to polish the water to a pure and ready to dilute quality.

Treatment Process


Particle Removal

Our cartridges offer outstanding absorption of sediment, dirt, sand and scale flakes to prevent filtration systems from blockage and microorganism growth.


Chlorine and Organics Removal

Carbon cartridges are a long established choice for the reduction and removal of chlorine, VOCs and heavy metals whilst reducing water hardness.


Reverse Osmosis

Pure water (permeate)  is produced during reverse osmosis by applying pressure to force water through a semi permeable membrane, leaving a majority of the present ions and dissolved solids on the other side to drain as waste (concentrate).


Post RO Deionisation

Our performance mixed bed resin is specially designed for deionisation directly after reverse osmosis. It holds a 1 : 1.5 ratio of strong acid cations and strong base anions to attract and remove all ions, salts and dissolved solids.
