What is the name of the process that removes potential haziness from a spirit?

Chill-filtration is a process specifically designed to remove potential haziness from a spirit, particularly in the context of high-proof alcoholic beverages. When a spirit is chilled, dissolved fatty acids, proteins, and esters that could cause cloudiness when the spirit is stored at lower temperatures can become suspended. Chill-filtration involves cooling the spirit and then passing it through a filtration system to remove these compounds, ensuring that the final product remains crystal clear at varying temperatures. This process helps maintain the visual appeal of the spirit while addressing issues associated with cloudiness, which might occur if the spirit is served chilled or at lower temperatures.

While carbon filtration, activated charcoal filtering, and reverse osmosis are effective techniques used in the production of spirits for different purposes—such as removing impurities, improving taste, or reducing certain undesirable components—none are specifically focused on addressing potential haziness in the same manner as chill-filtration. Therefore, chill-filtration is the most appropriate and accurate term for the process described.
