The XS range of filter sheets has been developed for use in the filtration of distilled spirits. The filtration of distilled spirits is vital to ensure life, stability and good clarity. To this end, the removal of hazes and the precursors to haze formation is particularly important. There are two types of haze and precipitation problems associated with distilled spirits which can be broadly classified as chemical (such as trace metal contamination) and physical (such as ethereal oils). Standard filter sheets contain small quantities of trace metal extracts such as calcium, magnesium and iron. The XS range is manufactured in a way that results in extremely low levels of these ions being present, making them an ideal choice for spirits filtration.
