Final/Sterile Filtration



Final / Sterile filtration

Final / Sterile Filtration is performed immediately prior to bottling on wines which require a higher level of bacteria removal including some reds, white and sweet non-fortified wines. In these cases media in the range of XE400H - XE1200H providing particulate removal capabilities of 0.6 -> 0.2 microns (nominal) are appropriate, again in either sheet or lenticular format. These sheets provide carefully controlled pore sizes to ensure excellent sterilisation characteristics. Typical flow rates would be in the range 400 - 250 litres/m2/hour.
