Sterile Filtration or 'Cold Stabilisation'

Cold Stabilisation of beer, often called ‘Sterile Filtration’, is used to remove all spoilage organisms from the beer. It offers a viable alternative to pasteurisation, particularly in the medium sized or small brewery where it’s considerably lower capital costs will be a major advantage, but also in any brewery where taste is paramount (filtration will not adversely affect the taste of beer). Where flash pasteurisation is or has been used it offers a simple replacement (as the hygienic handling and filling protocols and equipment will already be in place).

For this application, Amazon SupaPore VPW cartridges rated at 0.45 micron absolute would typically be used.

Again as with Trap Filtration, the housing should be fully flowed, fully draining and suitable for CIP (Clean In Place) and/or steaming. The Amazon 62 Series and 64 Series are ideal for these requirements, as are the Amazon 70 Series housings.
