How do you harvest or reuse yeast?

[mmaguy41]

Ive heard people saying they use harvested yeast, how do i go about doing that, and is it only worth doing when using an expensive liquid yeast?

the link above is great, though i have in the past I just brewed with the previous slurry if kegging and brewing same day.
Now i collect yeast from the bottom of the fermenter (conical and store a jam jar in the fridge then reuse) if I am going to be doing another brew within the week. Otherwise I don't bother.

I've had great success with it Martin, but you do have to be prepared to wait up to 36 hrs for the colonies to appear.
I don't use starters, perhaps I should!
My oldest culture is a TTL at 3 years, still fires up!

Do You Mix it with Glycerin Jim? or what is your procedure, as I have got some yeasts that I want to freeze. :thumb:

I rinse it a couple of times, acid wash, rinse again and then bottle and freeze!
Not exactly rocket science, but it works for me.
