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.
A vial (soda bottle preform) such as the ones used by White Labs is about 45ml. The 250ml that I recycled was enough to fill up 5 of those. Since I shot this video I equipped myself with a hemocytometer which allows me to do more precise yeast count. Back then I used the vials as a measuring tool. So James Snyder I would not use all of the 250ml. Only 1/5 of it. If it was a lager yeast I will use 1/2 of the 250ml. And I make yeast starters if the yeast spent more than 10 days in cold storage. Thanks for watching.
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.
That's a pretty solid process. I had trouble understanding why folks don't create a yeast starter large enough to split off half in a storage container for the back of your fridge and the other half for your brew. But, you've demonstrated clean yeast as output and elimination of starter process in favor for this one. Something to seriously consider. Nice work.
From a video stand point, Copy time section 3:17 - 3:27 and simply paste it to the very front of your video's intro. That time slice will grab your audience and hold them. Cheers.
Andrew Wade, it is 2l in size. That's the biggest one I found online. And Mican Epps, I just got a ring stand. It doesn't make things much easier, but it looks so much more professional then the old whiskey box that I used for the video😁. Thank you all for the kind comments
Nicely done video, greatly informative. I also like the way you have adopted English, the subtlety from your first language is pleasantly engaging, your accent holds a viewers attention.
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.
Thanks for this video. I just received my funnel in the post from eBay. And I am already using it. I just love how easy it makes washing your yeast. I look forward to using my own cultivated yeast.
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
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.
with minimal equipment cost you got a badass setup going man. Well done. Im going to probably get one and give this a try. Thanks for making the video!
Simply awesome, man! I have been dying to try this method. I finally ordered a separatory funnel, and it should be arriving today. Can’t wait! Thanks for the great video!
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've been collecting my yeast for the carboy directly, swirl around, wait to settle a bit and then siphon in a beer bottle and then cap it. However i get in some trub and that makes the yeast feed on it and ending up with some "eruptions" occasionally and that lead me to look for a separatory funnel but thought they are very expensive so I will build my own. 1 gallon jug, a rubber stopper with two holes one for a bottling wand and one avoiding building the vaccuum. Key is finding a jug/bottle that has a large and nice long coned neck. Excellent video Tsenko!
Constantin Moisei That's a great idea Constantin. Carlo Rossi wine 1 gal. jug might be just what you are looking for. They have a wide opening in which a carboy stopper fits just fine. I use those for small experimental beers. Good luck.
Another cool idea to avoid contamination/exposure is to use the stopper straight on the carboys (I have the small opening ones). Pour water in,, wash the yeast then turn it up side down then release all the trub, then only collect the yeast! TADA. need to find small stainless valve and make the tubing from SS. I;d need to build a carboy stand :)
cool video, SHMBO will not let me play with fire. Thanks for the tip. When I get my beer lab built I will be buying one of theses separation flasks. You really should add an affiliate link to amazon for that so you can get a little kick back overtime someone buys one!
just wanted to point out that whenever using a separatory funnel, taking the top off allows air pressure to push down on the solution and speed up the flow of liquid out of the stem. Capping and separating slowly increases the volume, but not the temperature or number of air particle, so the pressure decreases to compensate (PV=nRT)
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.
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 =)
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.
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
It seems with the torch, the up draft created draws in more surrounding room air making your immediate work area dirtier than if you left the work area stagnate. It also creates air turbulence to draw in and mix more airborne contamination. Yes? And turn off the HVAC & Fan during your working to simply work in a calm air environment. Another suggestion: Hours before starting to wash your yeast. Charge/feed the yeast with some sugar. A teaspoon or two. Then, close the large vessel and allow the yeast to produce CO2 and build pressure. Outgas the vessel a few times as the yeast creates it's CO2 pressure. This will assure oxygen is being expelled. Remember, CO2 is heavier than Oxygen and the yeast will create a CO2 rich gas in the container.. This will purge the vessel of other bad stuff which grows with oxygen. Yes? Third, syphon. Draw out your fluids by syphon to limit capturing more undesirable things during your fluids and yeast transferring. Limit pouring.
You are a really professional home brewer man. Good for you, and thanks for sharing how to separate yeast from beer/water. I wonder if you stored the yeast for 24 hours in the separatory flask in the fridge or if you left it outside at room temperature?
It did sit in my chest freezer over night at 36°F. The cold deactivates the yeast and it helps it to quickly settle to the bottom. Thank you for watching Carlos. 🍻
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?
Outstanding video dude! Just a quick note on safety but maybe a small, desk top fan angled up next to your fermenter might be a a better way to go. I'm pretty clumsy and working with limited space, I can easily see myself knocking that torch over and causing some serious damage. Anyway, thanks for all the good information!
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.
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.
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 !!
Instead of seperating flask please use long pvc bag. . Fill it with your liquid. Let it sit a while than after you see the boundary between the water-alcohol mixture and yeast please firmly press the boundary outside from the bag with a ruler for example .. that will quickly seperate the two layers .. than dispose the top useless liquid
Some sanitization issues I see, using hands on lids (even on the edges) without spraying hands, and also the open mouth of the flask while using the separation to let the yeast drop. If you tighten up the sani protocol, you have a neat process. TY for showing me this.
I'm confused. You're saving the "sediment" from the bottom of the separatory flask. What about the liquid on the top? I never did this, but I watched a different video about harvesting yeast with mason jars. What they saved was the liquid on the top of the jars, discarding the few layers of "sediments" from the bottom. I'm surprised with that amount of "sanitation solution" in your video. So I always had the idea that the good stuff is always on the top. Am I missing something??
Hey cheers from Argentina, great technique and video. Just one question, how much yeast will you use for example for a five gallon or 19 liters batch? We use dry yeast so I don't have how to compare amouts, thank you!!
Knowing the thickness of the yeast slurry when using this technique, I have found that 45-50ml of yeast and a yeast starter of one or two liters works the best for the ales I normally brew at home. The amounts vary because it matters how long the yeast stayed in cold storage and what your O.G. is. My rule of thumb is that if I am brewing a beer that will finish at ABV lower than 5% I need to make 1L starter and 2L starter for the beers with ABV higher than that. For Lagers the original amount of 45-50ml will go up to 90-100ml. Cheers back to all Argentina!
How many times or actions do you notice where you contaminated your materials by placing the top or other components on the table top instead of into a sanitizing bath, and then replaced those contaminated materials back on top of something that would contaminate your yeast?
Great vid. I find exactly the same 1000ml flask, but I can find much cheaper with glass stoppers. Often glass stoppers are held in place by an elastic band, and I guess glass is more trouble free and hygienic. Is there any reason why you couldn't have used an elastic band with the 500ml one you had?
Great video, thanks! How about cleaning yeast from dry hopped beers? Is that an issue? Also, how long can one store the yeast in the fridge after cleaning as you just showed in the video? Thx!
Great video, Tsenko. Do you have a video where you then transfer the yeast from the flask down to individual viles? I ask because I worry about viscosity. Is this a problem? Thanks.
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 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?
I'm someone in the science field and I'm always surprised by how creative homebrewers can get. You're a clever, bro.
