I have also come across this famous sticker on yeas washing: https://www.homebrewtalk.com/f163/yeast-washing-illustrated-41768/
There is one thing that puzzles me about this process: what is the point of keeping 4 mason jars in the fridge when you could just open them after a couple of days (once the yeast has formed a nice layer at the bottom) and dump most of the excess water. Swirl with the little bit of water you leave in the jar (just to stir up the yeast at the bottom) and pour the content of the mason jars into one. Less space, 3 empty jars to wash more yeast, and you will need all the slur eventually for a 5-gallon batch (if you dont make a starter).
Any ideas if this would be a good idea to do (or good practice)?
