After the fermentation stage the wine is subjected to a process of coarse filtration to remove any large particulates, typically the grape solids. Due to the volume of spirit that will need to be filtered, a coarse particle removal stage is required first, then advancing to a smaller micron particle filter. This will allow the large volumes to be filtered quickly before a finer stage of filtration to ensure a smooth wine.
Coarse Particle Removal
When source water is particularly dense with large solids, it calls for a solution of filtration to withstand higher flow rates and utilise higher surface areas to rid water of heavily populated particles.
