Thanks for the Info! It is super useful, for a Rookie like me who’s starting to build up his own home brewery, I have just saved the yeast Cake from a Kveik Voss from a Conical fermenter, but still having not super clean yeast from my last Christmas beer, with some spices.
This is such a brilliant solution to a common problem. It would seem that you could even over pour and quite easily drain the trub via the flask and retain more yeast. Thanks for sharing this idea with us. Cheers.
in plain English, a separatory funnel is used to either dry a chemical or wash a chemical I am a chemistry major i realize this video is quite old but figured why not answer your question ..lol hope it was not keeping you up at night =)
Thank you Scot. If you are doing everything wright, meaning the yeast didn't get infected before you wash it, you can use the same yeast over 10 times.
@@scotloggan1885 I'll be surprised if they do. If they sell them, it will kill their sales of yeast. Look on the internet for "separatory funnel". There is a wide variety of sizes and prices, but knowing that the price of package of yeast is now close to $10 it will pay for itself in no time.
Great video. I’m very new to all grain brewing. So not trying to be a jerk here with my new opinion. What about just making a rally large starter and just saving some of it back? That’s way you don’t have to wash any yeast at all. Maybe you still need the separatory funnel though?
1:11 "it's being used in the laboratories - it's called separatory flask. Now I don't know what they use if for in the laboratory" Bro, they use it for the exact same thing you're using it for! :D To separate (at least somewhat) liquid matter of different densities - hence the name: 'separatory flask'. Great video, btw! Thx for sharing your knowledge.
You are so adorable! =) Beer in one hand and happy yeast in another! I am a Chemist, and getting laboratory gear for homebrewing it's so much fun!.. I agree with the other comments, get a Cast Iron Stand with 24 in rod height, diameter of the rod 0.5 inches. Get a support ring 5 or 7 in diameter. Your separatory funnel looks like a 2,000ml volume. Great Video! Cheers from San Diego, CA
I do not know whether Tsenko still sees this or not, considering he has only one video which is published four years ago. Anyway, he is a genius! It is costly to buy a separatory funnel, but it is the most efficient way to 'purify' yeast!
I think I should throw in a tip.. If you already own a separator with iron clips... Use a pressure cooker or an autoclave to sterilize it.. this won't cause corosion. Great video amd great take on yeast washing. Thank you from India! P.S. Also Removing the cap)or slightly opening it from the separatory funnel will help speed up the yeast flow when decanting.
Never do this to save money. ( Do Not Reuse Yeast !! ) When you are ready to brew make a yeast starter split into 3rds pitch 1 and put the other two in the refrigerator. No need to wash or clean yeast.( will last 3 months in refrigerator ) or drain off beer and add sanitized water then freeze.( will last 2 years + ) P.S. Always make a yeast starter when you brew !!
EXTREMELY helpful, man. I greatly respect your style and passion for science. The other videos on here about yeast washing from obese dads who contaminate everything with junk. I learned a lot here and can apply some concepts here to other principles.
I have also found the pouring from jar to jar to be not great process. My solution has been to use a large syringe to suck off the top. You could use this in your initial step to get a cleaner start. In your separator I guess you will also get some trub. I guess you pour this off first.
You need to feed the yest daily or how do you keep it alive? How offen you need to feed it? What do you feed it whit? Or you just keep it in refrigerator?
Dude......your a brewer, that makes you a chemist lol, basically your a chemists with a very specific area of expertise which is brewing alcoholic beverages and cultivating yeast Edit: and your using a torch as a bunsen burner just like a chemists, genius!
Tsenko,Thanks for the great tutorial.I bought a flask and it worked outstanding with one exception and that was I could not get the yeast to flow. I tried 2 separate times and eventually I sterilized a paper clip and shoved it from the bottom of the flask up thru the stop cock valve and into the yeast. I know I was in the yeast as some yeast was on the paper clip but no real visible movement / draining of the flask. I then got on a 1 hour conference call and inadvertently forgot to close the stop cock valve. When I came back in an hour, the flask it had emptied itself. I don't want to repeat this next time I go to wash my yeast So that leads me to ask you - Have you or did you consider drilling out the stop cock valve so the hole was larger to allow the yeast to drain easier?
So when you reuse this yeast, do you have to reuse it for the same type of beer you brewed with it? I understand yeasts are for different styles of beer but I mean reuse this particular yeast remnant for the same beer brewed before. Does it have any leftover taste from the last batch?
No. You don't have to use it for the same type of beer. If you used it to make an IPA, there might be some residual taste in the washed yeast. In my experience it has never been enough to effected the next batch, even if is a beer with a clean profile.
The "plastic" stopcock on his larger sep funnel is likely PTFE, aka Teflon. It's chemically inert and non-stick, so it won't degrade, and is easy to turn without requiring lubrication. These are the go-to whether you work in a chemistry lab or in your kitchen.
Hi Andrea. It's the same as storing a package of comercial liquid yeast. Storing it for more than 3 months would mean that you need to work on revitalizing it before pitching. Thanks for watching!
Great video. Thanks for taking time to share this. I have a couple of questions. 1. Do you use all of that harvested yeast in the next brew? 2. Do you need to make a yeast starter the next brew to get yeast going? 3. How do you separate the yeast and store it? Thanks Paul
so the 2L funnel is less common/ more expensive/ harder to store . 1L seems to be the most common larger Separatory Flask. I plan on doing 5 Gallon batches so is 1L large enough or will it be hard to make the 1L work well? Also I'm wondering about the temperature you use while settling. You mention the 1st settling in your chest freezer and then there is the 24hrs in the Separatory Flask.
Sorry if you've already answered this, but that cleaned sample of yeast in the vial, was that just sanitized distilled water? And does the yeast store well like this in the fridge?
great tips thanks!
In that trub there is food for yeast and dont throw awey everything...

WOW!!! SO COOL!! I've never heard of washing yeast. How many times can you use it? I Really liked your video!! I'm just blown away man🤔😀

Was the water you poured into the carboy sterilized somehow?
Yes. It was boiled for about 10 min. and cooled down in my freezer.
Hi man. The best video I've seen about yeast recicling. Congratulations.
Really great method. Thx for sharing!!!
How many beer you have when you filmed this? lmao

Very well done.
Star San isnt acidic it's an oxidizer. That's why it rusted the steel.
I'm someone in the science field and I'm always surprised by how creative homebrewers can get. You're a clever, bro.

In chemistry it's called a separation funnel, and I've had many a good(?) time with the ol' "sep funnel'

greetings from Mexico
you keep it in the freezer or in the refrigerator? and for how many days can it last? By the way, great video!!
Use ozium to clean the air
Thx man ! But what if I used cryo hops for dry hop ? will it still separate ?
Very clear directions. Answered my questions. Good video
6:10 very important information here.
I've been looking at so many videos and none of them were as clear as you when it comes to explaining the entire process, glad I found this
where do you get those glass vials that you store your yeast in?
Search the internet for "Soda Bottle Preforms".
Great video. Really appreciate the great content

Would this work for mead yeast harvesting as well?
It definitely would Robert
Great video - thank you
Sorry that was wank as
Great idea I think I will make one out of a soda bottle just need a valve on the cap side.
