trub pitching question.

[Gymrat]

This is a few weeks down the road but I am curious. Let's say I do some kind of light ale on week one in my conical. Then a darker or more potent ale on week two and use one of my buckets. Let's say I want to drain some of the trub out of my conical and pitch it as yeast into my bucket. How would I go about that?

I think that as long as you keep it in the fridge, it'll last a week. Otherwise, just use mrmalty.com and put it in the bottom of your fermentation bucket and rack the correct temperature wort right on top of it.
A few months ago with 05, I left about 3 tablespoons of yeast cake in the fermenter. I didn't use the same fermenter but just transferred that yeast to another one and racked on top of it.
And another time I kept the yeast in a mason jar for 6 days in the fridge (filled to the top) and used a bit more than 3 tablespoons and both took off well and came out fine.

a quick way to grab some used yeast from the LBK's or your conicals...

drain off your beer as you normally do.

Have a quart of sanitized water handy.

Pour the water in the fermenter...agitate.

after 15 min, drain most of the slurry off as you would do a bottle of beer.

what you just got was enough yeast for a few vials....or the ability to really kick start your next batch. But drain off the excess water before use.

Roger, I guess it depends where your drain is on the conical. If it's at the bottom I would drain off some trub/yeast just before pitching. Use a glass quart jar so you can see. I would think that dead yeast will be at the bottom and that you will see a color change when good yeast starts to come out. Stop draining a throw that away. With a new sanitized pint jar collect (heck I don't know, I'm winging it here) 1/2 pint of good yeast and pitch that into your chilled wort.
Like I said, don't know for sure, but if I had a nice shiny new conical that's what I'd try(insert conical envy here )
Always make sure you have back up yeast and you may want to do a trial run first.
As always let us know.
