Filtration Solutions for Spirits Manufacturers

The two key concerns for manufacturers are the removal of particulates and the prevention or removal of chilled hazes. Particulate removal is achieved using depth or pleated depth filters to achieve desired clarity at various stages of the process (post maturation & dilution/blending; pre-final bottling).

Removal of chilled haze is more difficult problem. Every distilled dark spirit has a unique flavour due to a distinct variety of compounds they contain because of their raw materials and from the ageing process in wood barrels. Hazes occur for several reasons; lowering of temperature or when dilution with water prior to bottling takes place. We need careful selection of filter products, when removing hazes, to ensure we do not remove esters which will impact the desired characteristics of spirit.

In light spirits activated carbon filters play a key role at various stages of the process to correct colour and odour combining with depth filtration that ensures the brilliance of appearance of the final product.
