my Home made cider is clearing out by its self?!
Answers:
Different yeast strains flocculate at different rates. If kept at their optimum temperature (varies by strain) and pitched at the optimal rate (varies by SG) they will consume available saccharides and then fall to the bottom of the fermentation vessel.
I brew beer, not cider, and the initial fermentation is usually complete within a week and sometimes within 4 days. Fermentation will often continue for another week or so, but the beer will have already started to clear.
Cider does seem to drop it's sediment faster than ales/beers.
Never known why.
