Yeast cropping

[Hound_Dog]

I'm planning on trying a spontaneous fermentation later this year, and if it works I would like to save some of the yeast. I have an idea of a way to crop a sample of yeast to save. The reason I devised this plan is that I've heard that if top cropping yeast that it isn't recommended to hold on to the yeast for a long time. I'm wondering if I run a blow off into some pre-boiled water if it might keep for a while should I attemp to reuse it at a later date. My thought is that If I put two holes in the top of a mason jar, that I can put the blowoff through one hole and an air lock on the other to keep the blowoff sanitary. See ghetto diagram:

Is this just stupid enough to work?

Yup. Do your best on keeping the level of the brown high and the length of the tube short, it will work.

Wow. That has to be some vigorous fermentation to make waves in your fermenter.

I'm just that good. The beer I brew is so vast that it has tides

I did this once, and it worked. But beware -- if there's enough yeast blowing off, it will fill the collection jar and start blowing out the airlock! It happened to me. If you sterilize (not sanitize) the jar, you should be able to get away without any boiled water, which would improve the capacity of the jar...

Any reason why you want to top crop the yeast instead of washing the yeast after you transfer?

He's just fermenting during a full moon! Tides are at their highest
