Default yeast farming

I was reading about yeast farming and it seems like a good way to save some coin, from the sounds of it you just make a starter, drain the wort and dispense the yeast into several containers for future use.

Does anyone know if bottles would work for storage? Once the wort is drained and the yeast goes in the fridge they will be dormant right?

Just make sure that you wash the yeast well (removing any wort so that fermentation is not taking place), and relieve any pressure from the bottles a few times near the beginning of storage.

Otherwise it'll build up pressure and you could get bottle bombs or a yeast eruption when you open them. (I had this happen once--thank God I was in the basement.)

It' probably more convenient to use a mason jar or jelly jar or something where it's easier to relieve the pressure and re-seal.

mason jars with a #13 stopper and airlock work well...

At this point bottles would be easier, how full should I make them? 2/3s??

At the very most, I'd say. If you get the yeast washed (trub and excess water/wort removed), 1/2 a beer bottle of slurry is a lot of yeast. (Compare to the amount that comes in a White Labs vial.)

How exactly do you wash yeast? Soap and water?

Not sure if you're really asking in earnest, but...

Clear containers might not be a bad idea, but then again I'm not sure about light damage to yeast.
I've heard once the yeast turns the color of peanutbutter it supposed to be tossed

I think I might give it a try this weekend. Liquid yeast runs me $6.50 locally so if I could turn that into several brew days would be nice.

well call me a rebel but i've been collecting yeast and capping it in 20oz. corona bottles with absolutely no problems. your milage may vary
