Chill filtering is a method in whisky making for removing residue. In chill filtering, whisky is cooled to between 5–10 °C (41–50 °F) and passed through a fine adsorption filter. This is done mostly for cosmetic reasons — to remove cloudiness — however by many whisky drinkers it is thought to impair the taste by removing the details which differentiate between the many distilleries. It is only necessary for whisky that's bottled below 46.3% percent alcohol, as the cloudiness does not occur at or above this concentration.
