I have a question about the Mr. Malty "Repitching from Slurry" calculator. When the calculator specifies "# ml of yeast needed" does this mean pure yeast or a shaken-up mixture of beer/yeast? For example, like the pictures of the mason jars above, do you decant the beer and pitch X ml of pure yeast, or shake the jar and pitch X ml of the combined beer/yeast? Thanks!
