Distilled Spirits

Graver Technologies distilled spirits filtration products protect spirits from contaminant and quality issues.

Innovative Technologies for Distilled Spirits

Filtration of distilled spirits can be different than that of other alcoholic beverages due to high alcohol levels which prevent the presence of microbes. Consumers are more concerned with visual and aromatic aspects- expecting a clear and bright product. Manufacturers need to deliver a bottled product free of suspended particles and without the risk of chill haze formation. Contaminant risks can vary greatly, ranging from carbon from the aging (char) or mellowing process to colloidal materials from fruit-based additions, to haze formation that can occur post-processing. Filtration processes are designed to ensure the best flavor, color, and clarity are achieved in the final product.
