What's needed

To steak yeast onto a plate you'll need:

  • a flame source for sterilizing the inoculation needle
  • an inoculation needle. A piece of wire works as well, but inoculation needles are cheap and you should pick one up when buying the petri dishes
  • a sample of yeast. This could be an empty Wyeast smack pack, Whitle Labs vial, dregs from a bottle conditioned beer, an active fermentation, yeast sediment .... In this case I had an old White Labs vial into which I filled sterile wort to get the yeast fermenting again before taking a sample.
  • an petri dish with malt agar that has been prepared in advance. (See [Making Plates Slants])
