Colorado Boy Brewery - Conical Yeast Harvest

How to harvest from a conical to a yeast brink

[mkblackmart]

Thanks for showing the process. Quick question: you purge much of the oxygen in the corny with co2, but is there still oxygen in the tube running from the conical to the corny? Does that oxygen, pushed by the yeast, infiltrate into the co2 blanket in the corny, or does it rise to the top pretty rapidly? I've heard mixed messages about how rapidly co2 and oxygen separate inside vessels.

awesome vid. pls hold phone on the side to film :P

Great video!! 2 questions: Do you cold crash prior to harvesting? How much pressure do you find you need to put the tank under?

You realize that homebrewers like me are watching this with jaws on the floor, right? Aside from the fact that you dumped out about a billion dollars (in homebrewing terms) worth of yeast because it had the teeniest bit of trub in it, you still managed to grab 25lbs of stunningly clean and raring to go yeast. (Great vid, though!)

Great video, glad you're back into them. You have one of the most useful collections of brewing videos in YouTube!

But one question: why vertical? :-)

Cheers!

Thank you for the great video. Could you please tell me what beer style the yeast harvested from? Since the yeast is super creamy, i guess the beer doesn't get dry-hopped...

[primetimez]

2.4 billion? So you would just pitch that right into your fermenter tank and that would be enough for your next batch? Depending on how many bbls your brewing 10? Is that enough yeast? Or are you going to step it up for the right amount of pitch rate?

Is simply injecting CO2 sufficient for the 'blanket' or do you require something specialized?

[goodolarchie]

You don't track what generation the yeast is? Do you just keep reusing in perpetuity?

this is a really bad video when im currently having food poisoning haha. GREAT VIDEO !!!

[Lemieux]

I guess its not a dry hopped beer? How do you collect yeast when beer dry hopped, or this green creamy (hoppy) yeast is ok too?

[walterl]

very nice system! how many times (generations) you Harvest ?

[litolito]

super cool!!! that's just a modified cornelius right?

[JAWSFREE]

where did you purchase the conical? China?

[francop]

How is that yeast pitched? How is the process? Does the yeast need washing?

[indabebe]

how did you find out how many cells you collected?

[muzguz]

That would've taken some counting of the yeast cells. Phew.
