Would dumping cold water on top of a yeast cake, before dumping the warmer wort, harm the yeast? I'm assuming that cold water wouldn't harm the yeast because liquid yeast is kept in refidgerated conditions before using.

sonvolt said:If I were you, I would do this - Sanitize a spoon and a mason jar. Then, being very sanitary, collect a good amount of your yeast cake into the sanitized mason jar. Clean your primary fermenter as you normally would, add your cold water, dump your wort, and ensure that you are at the proper pitching temp for the yeast strain you are using. Then, dump your harvested yeast from your sanitized mason jar.
Be careful with cleanliness.
This will get you what you need with less stress to the yeast than rapid temp changes, IMO.
