BrewHound · Post by **BrewHound** » Mon Aug 02, 2010 2:26 pm

Hey all, it is time again for our monthly tech meeting.

This meeting will cover yeast culturing at home. We will go over the supplies need for culturing at home, making the media to grow the cultures on, plating, incubating, and storage of cultures.

We will be culturing White Labs 013 London Ale yeast, unless someone has another one that they are wishing to culture that they will be using before that.

Damn TOM BURNS! You are going to bring a yeast expert to this. Not nice. I have read a good bit, however, I have only cultured 2 samples to date. Guess I will now have someone there to point out all of my mistakes, Like I don't do a good enough job on my own of looking like an ass, now you are bringing me assistants.

I new a guy that worked with yeast at red star, Jon. He can to Teach a Friend to Homebrew at BA's a few years ago. One thing they do hear is supply yeast for ethanol production. I think it is still a French company.

Thanks for coming to the meeting Rob and Kelly. It was great to get your input, though I might have more questions. Hopefully we'll see you around some more.

I agree strongly with Tom sentiments.

Thank's a bunch Rob & Kelly, you really added to the tech meeting. It was wonderful having someone there with so much knowledge and experience with yeast culturing.

We hope that you will consider joining us on a regular basis for tech and social meetings and perhaps joining the club.

Just as a follow-up on the last meeting.
For those of you who are interested in starting to farm brewing yeast please feel free to contact me if you have any questions on places where supplies can be had.

I also intent to follow up on this topic by posting a white paper to the forum that has the recipe for the culture media some instructions on creating a sanitary environment and where to get supplies.

Also Rob was kind enough to leave some culture scrapers and pipettes at my place for culturing if anyone is interested in some of them please just let me know.

I assure you it was our pleasure. We had a great time and great beer to boot. I suspect I will be seeing you all again at the 8/19 regular meeting and perhaps bringing another friend or two from work.

If anyone is interested in glassware please post your wants and I will bring what I have then.

Rob,

Let me know how much you want for a couple of the 1000ml flasks and maybe a 2000ml flask. Also if you have any stir plates if you have time to look around. I think thats all I really need for right.

Thanks again for all the great information,

Kurt

Sorry for the delay, things have been crazy at work. Anyway, I am planning to come to the meeting this Thursday and I will be bringing glassware with me. Here is a very brief list of flasks but if there is something that you want, post it, and I will see what I can find.

The pictures are generic but will give an idea of what the flasks look like.

Erlenmeyers http://utahbiodieselsupply.com/images/b ... flasks.jpg
25mL
50mL
100mL
150mL
250mL
500mL
1000mL
2000mL Wide Mouth (size 13 stopper)
4000mL

Flat Bottom Florentine http://www.indigo.com/images/product/572.jpg
500mL
1000mL
2000mL
6000mL

I also have tons of tubes for culturing, condenser tubes, vacuum flasks, filter flasks, fleaker flasks, nalgene graduated jugs...

Too much too list. I will attempt to bring some pics of my store room on Thursday.

For prices I am thinking $7.50 for 1000mL, $15 for 2000mL, $25 for 4000mL, and $35 for 6000mL. Smaller flasks we can talk about. I am not looking to make much money, just happy to clean out some space.

See you on Thursday.
