vue - Your Home Yeast Lab Made Easy - Making Agar Plates
In this video I demonstrate how to prepare, sterilize and cast two different (but cheap!) types of agar plates, both of which are suitable for growing brew-house yeast and bacteria. The recipes for the media used in this video, as well as the recipes for some derivations of these media, can be found in the associated post over at my blog: http://suigenerisbrewing.blogspot.ca/2015/03/new-video-casting-agar-plates.html

excellent, i learn a lot , this is so informative
-
Thank you again. Wonderful presentation.
-
is this psilocybe mushrooms?
-
Just tried to make some plates on Sunday night. Must have become contaminated somehow because now they all have a thin clear/white slim growing across the entire surface of all 4 plates. I even used the pressure cooker to sterilize the agar solution. I guess I'll try again soon...

Thank you for your excellent video. I found it extremely interesting and informative.
-
very informative. I would like to know if we can put the plates under a temperature of around 30'C (India) ? This temperature would be just the room temperature without the incubator.

thank you for the video
-
Thanks for the videos. You mention in the video that after the plates cool enough for the media to be relatively solidified/viscous, you should flip the plates over because of condensation on the lids. But then what? Do you try to remove the condensation by wiping with something sterile?

Is a great video for revision too!

How much agar powder should we add, is it ok to use unpowdered form of China grass

I learned a lot from your videos, I hope to see more videos about beer yeast, thanks, greetings from Venezuela

I have learned a lot from your videos.Exselant. Please can you tell me the name of the drops you used . I just cannot make out what you call this. Thanks Richard

Very useful and instructive ! Thank you so much !
Greetings from France. -
Thank you very much for putting this together. I am starting to plate yeast and have found these very useful. I have an excellent source of many different beers/yeasts/bacteria from my homebrew club to work with and can't wait to get my yeast bank up and running!

I really appreciate your videos. However I have a question.. When freezing the yeast at what ratio do you maix slurry/ glycerol and is 80% glycerol sufficient? I just tried freezing some yeast that I propagated from un sulfured sultanas and figs and mixed slurr at about 50%/50% with 80% glycerol. It's not really freezing solid in my domestic freezer though.

Excellent video! It's a perfect how-to video on agar plates. I have a question: Have you ever measured the specific gravity of the potato extract or somehow figured out how much sugar/fermentables it is contributing? When I pour agar plates, I usually use DME at about 7-10%, yielding an SG of about 1.030 to 1.040. At this amount of sugar, after streaking my yeast out, the plate grows to completion in less than a week. I was wondering why you make your DME agar plates at such a low percentage of DME? Thanks again for such a great video!

Really enjoy your videos! Any tips as to how we should wash glass plates?
-
Great video. I like this little series you are doing on home made yeast lab. Cheers and thanks for doing it!
-
another great video. One question. When you were demonstrating making the potato dextrose plates, you didn't say how much dextrose you added or if you did, I didn't hear it. How much was it? I'd like to try this method. Also, would you recommend making several plates to have ready at any given time or just make a few at a time?

Very awesome stuff, thank you Bryan!
