As the name suggests, clarification involves the removal of visible particles. This is also the stage where much of the bio-burden is removed to protect the more valuable final stabilisation filter stage.
To prevent refermentation in the bottle and spoilage organisms affecting the taste, appearance and shelf life of the wine, absolute rated pleated cartridge filters at 0.45 micron are used to remove yeast and microorganisms. With red wines, sometimes the final cartridge is 0.65 micron to avoid removal of colour.
Stages of Filtration & Water Treatment
Prevents debris, scale flakes, dirt and particle build up in pipework, tanks, equipment and where present, premature blinding of filtration stages further along the cascade.
To help clarification and to protect the final sterile filtration stage, absolute pleated cartridges are used to remove the bulk of the spoilage contaminants.
Preventing refermentation in the packaging is key to some producers and yeast removal is the main contaminant to be removed.
