Default Keeping yeast, re-using yeast, saving $$

I have some yeasty questions. I thought I remember people saying they used yeast from a previous batch. Considering AHS sells white labs for $6.00, this would be some savings. How is this done? How long can you keep it? Would it be a bad idea for a newbie? If you have any good links to this please post

search this forum for "yeast washing".


or, do what I personally believe to be a lot easier and make a very large starter with your yeast. pitch half in a batch of beer and save the other half in a sanitized soda bottle in the fridge. next time you need that yeast, either warm and pitch the contents of the bottle, or make another starter and again save half of it.

jackle:

some people wash the yeast.

here's what i do and i haven't had any problems so far.

I collect the yeast slurry into 20 oz corona bottles leaving an inch or so of liwuid on top. i also do not fill the bottles all the way up. i cap the bottles, label and date them, and place them in the fridge.



now what you will hear ppl say is "you need to burp them" but i don't and it works just fine. you'll also hear ppl say to wash the yeast but i do not with no problems.

I agree with Brew Head although I find 20oz PET soda bottles more convenient. You can also split a batch into individual bottles by pouring off the beer, adding sanitised water, mixing well and dividing between the bottles then topping up with more sanitised water. Its more important to make a starter each time if you do this particularly if you've kept them for some time.

I just pour the slurry from a primary fermentation into two or three sanitised bottles, seal them and throw them in the fridge. Four batches or so is enough economy for me from a WL tube.

Ya know, I'm wondering if it's worth the mess and hassle of washing. This sounds like a good idea. 5 brews with 1 batch. Anyone care to tell us why this wouldn't be a good idea?

You really want to add the old hops, break material, and other trub to the new brew?

Good point. I do notice that within 1hr of transfering to primary there is a "little" bit of trub. Might be the yeast settling and getting acclimated?

I wouldn't imagine my hot/cold break makes it to the primary. I use a hop-bag and I don't think much of that makes it either. I have a good amount of crap in the bottom of my keggle after a swirl and drain.

This isnt a problem if you use a bucket type FV and are able to skim the krausen
