Frozen Yeast Bank

Postby Legman » Thu Dec 04, 2008 10:00 pm

I've currently been repitching yeast into new batches of brew collected from my primary with good success. I've been storing it in glass pint jar in the fridge till I'm ready to brew again. I'm not sure how long these will keep like this and some strains I may not use again for a good while.
So, I was doing some research on long term storage and I ran across this write up. Seems like a great idea!
It would be really cool to be able to just open up my freezer and choose from a variety of strains any time of the year and without paying good money for each vial of yeast every time. I'm going to give this a try and see how well this works. Should be interesting.
Any one else trying something similar?

I thought morebeer had yeast culturing kits available again in their new printed catalogue for next year.

They do have a couple of books available

microscope

Postby slothrob » Tue Dec 16, 2008 9:38 pm

I've only picked bacterial colonies, never yeast colonies, but I don't think you would need a microscope for picking streaked yeast colonies. You would need a microscope for counting cells, if that's what you want to do.

Legman,

Thanks for that url for the tubes. I'll be ordering 30 of those to get started.

Not so sure if i'll get the microscope tho...i still have to read up on these processes quite a bit...and i'm leaning more towards the kiss approach as well..

I haven't seen any yeast culturing products from NB...but that doesn't mean that they don't have anything... I'll do a better search on their site to see if i can find anything...I really wanted to create slants and store them, but using the tubes that you mentioned would be quite effective and probably a lot easier to do.

Thanks again for your insights and info.

Yeast Kit

Postby Legman » Wed Dec 17, 2008 6:29 am

Country Wines has a yeast bank kit. It's basically a few test tubes and some "Freeze-Shield" (which I'll bet is nothing more than a glycerin and water solution).

Great! Thanks.

Would you know where i can get any smaller tubes than the one shown on either of these suggested sites? I'd really like to have tubes about half the size of these. I'd do a search today, but i'll be catching a flight to go back home today from the great white northeast. Can't wait to get back home!

Thanks again!

Success!!!

Postby Legman » Fri Jan 23, 2009 6:59 am

Tested out the frozen yeast this week.......and it worked!!! :D
I pulled a test tube from the freezer (frozen solid) and placed it in the fridge to thaw for about 5 days. Then made a starter from DME.
I was a bit worried at first. For about 2 days there was no activity and it looked dead. But just when I was getting ready to try something different, it began.....and it was alive! :mrgreen:

Now into it's 3rd day, things are starting to look like a normal starter. It was a little slow to start, but it looks like you can freeze yeast and bring it back from the dead! Now to build up my yeast library. This is so cool! 8)
