Yeast Culture Trade

[mindless2]

I'm going to freeze 6 samples of each in 50ml tubes...
This was my simplest route...
But there are so many variations on this....

 

[PoppinCaps]

I threw the samples I got from poppincaps in a small amount of starter wort and they've all taken off nicely and smell how I would expect them to smell given the yeast strains received. Overall I would call the trade a success.

Indeed it was, had 5 vials of each frozen down within 4 days of checking the mail. Highly successful.

Out of curiosity, how do you guys bank your yeast for long term storage?

 

[PoppinCaps]

Decant beer, split slurry to several vials, add sterilized glycerine to final concentration of 10%, mix and freeze. Good for a few years at least.

Make a starter wort, unthaw vial quickly and add slurry to starter.

 

[mindless2]

What are you doing to thaw the vial quickly?

 

[mindless2]

oh do you also add the glycerine mix to the vial and then sterilize in pressure canner?

 

[PoppinCaps]

I put the vial in a glass of lukewarm water to thaw just before pitching to the starter. I make a stock canned solution of 45% glycerine and pressure cook it. Then add 3 ml of that to 10ml of slurry whenever I need it. That brings it down to about 10-11% final conc. You certainly could sterilize each vial with the glycerine already in it so it's ready to go.

I'm going to be prepping some samples for a member on here in the next week or two. Is anyone interested in trading for any of the strains listed above?

What I'm after

As pure as possible set of Brew Tek yeast.

Count me in! My flow hood will be here next week.

I have Brew Tek, but I'll have to propagate to test its viability.

I swore there was another thread dealing with this some time ago that I replied to. I'll look around.
