Yeast Cropping

To add precision to yeast cropping, accurate cropping of yeast from the fermenter from the fermenter cuts costs by preventing beer from being transformed to the brinks.  Measurement is typically in percent solids by volume.  Optical differentiating of yeast and beer is ten-times more accurate than weight densities of yeast and beer.
