I currently maintain a small Yeast Library for myself and also to share with local brewers. These yeasts are both from my own collection, and from donations by friends, club members and fellow yeast nerds from other parts of the world.

Yeasts in the Library are stored in duplicate - both frozen and on agar slants (working cultures).
- Every 6 months or so, the cultures on the agar slants are passaged to keep them going
- Once a year, the slant cultures are streaked out on agar plates to screen for contamination.
- I do not have a true cryopreservation freezer; the frozen master cultures are stored in 30% glycerol at -20C where they should remain viable for years.



These are the yeasts currently stocked in the Library:
