Clarification is the step of stabilisation of fermentation.
During clarification all remaining solids are removed from the fermented liquid.
Clarification done in numerous ways:
fining, a process that calls for the addition of substances that cause the solids in the liquid to adhere to one another and sink to the bottom of the vat
running the liquid through coarse and fine filters
siphoning the liquid off the top of the fermenting vats after the solids have settled to the bottom
