Chlorine dioxide tablets can be used to kill bacteria in the slurry when harvesting yeast for reuse, without the negative impact of an acid wash on cell health. Chlorine dioxide isn't a substitute for good sanitizing, so keep all yeast handling equipment clean!

To use, collect slurry from the fermenter, add cool sterilized water to approximately double the volume, swirl vigorously, and then allow trub to separate. Decant the top (yeast) layer into a sanitized flask, add one crushed chlorine dioxide tablet to the yeast layer, and top up with more cool sterile water to bring the volume to 1 liter. Allow to rest for several hours, then decant the clear top layer — the yeast can then be directly pitched into a new batch. Includes 20 tablets.
