A way to roughly calculate how viable your yeast is.
Yeast viability describes how many living cells there are in a cell population. The most accurate way to to determine this number is use a microscope and perform a actual cell count. This calculator allows you to estimate the viability of your yeast based on it's production date.
Initial Cell Count: Most all manufacturers publish the cell count on their packaging. Enter the cell count of your yeast.
Production Date: Most all manufacturers publish the production date on their packaging. Enter the production date of your yeast.
Calculate: Simply click the "Go" button to see the results of your viability percentage and viable cell count.
