This is a more advanced technique, but is an important one for anyone who wants to purify strains of yeast from mixed cultures or wild ferments, or for purifying yeast from an infected batch. Streak plating involves "diluting" yeast across an agar plate in order to get individual colonies. These colonies can be "picked", allowing you to produce pure strains from mixed, or infected, yeast cultures. As always, this video is accompanied by some additional information on my blog: http://suigenerisbrewing.blogspot.ca/2014/08/your-home-yeast-lab-made-easy-streak.html

Recover yeast from an infected batch of beer? More please.

I just purchased some agar, and I see now that it contains yeast extract and other nutrients. Will it be fine to use this one? Or do I have to buy clean agar with no additives? Thanks!

Thanks for sharing! 👍

many thanks for sharing

question about streaking- are you lightly touching the transfer loop on the agar or are you scraping in to it? And are you use the face of the loop down or the edge of the loop down? I've been trying this and it looks if i put too much pressure, I gouge the agar and scrapes little channels. Or I may just not be using enough agar in my plates?

Thank you for sharing your knowledge. Can you do a video on reproducing liquid yeast strains that is ready for brewing. In my country good liquid strains is hard to source, and ensure that they are in a healthy condition after being shipped.

Amazing stuff what a great resource! Thanks for subscribing as well!

Thanks for uploading these! I look forward to more!
