Here's a post I wrote detailing how I slant yeast. The process is pretty simple, and only requires mason jars, test tubes, an innoculation loop, stove and pressure canner and a few consumables. I've tried several other methods for storing yeast, but this is by far the easiest, cheapest and most compact. You only need a pin prick's worth of yeast to create the slant, and you only have to maintain them every 1.5-2 years (which is also very simple). This makes it so you can accumulate quite the bank! I currently have a bank of 23 yeasts, and it fits in the size of a shoebox. The only thing I will note is that the test tubes in my blog can be expensive. I recently switched to these centrifuge tubes instead, as they are much, much cheaper, and they should work just fine, reading the comments, but I have not tested them personally yet, so have not updated my blog. The only downside to doing slants is it does take about 7 days to get a pitchable amount of yeast, so you have to be able to prepare ahead of time.

Cheap 50ml tubes and a rack for them.

They aren't pressure safe like the preforms are, so make sure you're all gassed off before you seal it for long term.

I usually keep it in a jar with the lid loose for a while before I decant and move the slurry over to a tube for longer term storage.

Right now I've got only six strains, but I only recently started harvesting from starters. My go-tos tend to be:

  • WY3711
  • WY1010
  • WY1272
  • WLP007
  • WLP090

I picked up a 500 mL flask for this reason. I overbuild a starter, decant off 1/3 or so into the 500 mL and add more wort to top it up to ~300 mL. I also top up the 2000mL flask to build up the pitching starter. Once the 500mL flask ferments out, I cool and decant off the liquid, and pour them into vials that I picked up on amazon.

You need to make some slants. Petris in the fridge dry up and end up with water matted on the surface.

check these out . I haven’t used they yet, and make sure you get a tray so you can PC them. I’ve used the glass ones, but those are really expensive.
