Freezing Yeast.....How to.

[Ducatiboy stu]

Ok, before everyone goes " Oh here he goes with another yeast thread argument" here is a method of freezing yeast for latter use

The reason I started this was due to a fellow brewer who had frozen his dried yeast.

There was a couple of these threads a while ago, I think Wolfy did one and maybe bribie as well? Will try to dig them up...

Bribie (edit: beaten. as above maybe it was wolfy) did a tutorial about this a couple of years ago. Will try and find the link. I've had success with the method, still got some frozen samples from doing it a while back.

Bribies thread.

Both these threads got me into doing it and now I'm at 18 strains and working very well. I found these on my phone too by the way.

How long has the oldest viable yeast sample been frozen by anyone ?

I have a few samples frozen for around a year. Seem to fire up ok. I always do a small step starter first to get some life back into it though.

I prefer to split my pack 6 ways without smacking the pack as I think you get more yeast per sample tube that way.

I do 20ml yeast 15ml glycerine 25ml water per 60ml tube. I'm not changing my ratio because it has been working with ever strain I've split.
