This has been my long term brewing experiment under the last year. Used the same yeast over and over. Using my conical fermenter the Fermentasaurus as a kind of yeast washer. Maybe yeast washing isn't the best terms for it. But I used the collection ball to try to get rid of some trube and the "oldest" yeast.
So I just could harvest the freshes yeast end re-brew on the old yeast cake. I really wanted to ride this experiment out until things turned bad. And they did.

A little update, the glass used when the Dr was drinking the Christmas beer has since joined the "Me Too" movement.
Hans this is amazing. Just proof that if you know what you are doing you can get away with a lot of weird stuff that other people would consider non-sanitary.
I guess so!
Been using the same Wyeast 3068 for 3 months now, multiple batches washed and reused. Loving the cost savings for when I want to experiment with multiple batches! i still prefer to clean and wash the carboy after each use though.
Great 👍
Love this video! You have debunked so many myths with this experiment.... you are the best!
Thank you so much!
Dude.... that was amazing!!! Love how you turn some of these rules on their head! Love it!!!
Thanks, it takes a lot to do it!
@@DrHansBrewery I can only imagine! All the camera and editing stuff on top of the brewing... then the waiting.... truly appreciate your efforts! It is really great stuff... the video style is fun and educational.... did you ever think about doing a podcast or writing a book of your experiments and all you've learned? You're a true homebrewer, and it would be awesome for us other homebrewers to have someone like you to learn from and glean from... just a thought. All the best man!
@@robertmullins9639 Thanks, glad you appreciate my work I put in. Cheers!
That's a very cool experiment. I could never collect yeast from my Fermentasaurus trub jar due to it clogging every single time I've used it. Hopefully version 2 will fix that.
Never collected yeast with it either.
Here's what I gather from this video, screw scrubbing the ferment everytime let the yeast live on! This make me excited to see how my beers turnout now!
YES!!!
Home brewer's are lazy but you are the best."Probably I clean the fermentator tomorrow “
LOL
You have some really great beerxperiments! Something I have been wondering is how long could you keep a yeast strain going for. Do you think you could keep yeast going for longer than this? If so how would you keep it going?
My local brew shop in South Africa imported some Kveik, which proved to be both costly but worth it, being able to ferment at +35 Celsius in African heat is invaluable.I immediately made a large starter and separated the resultant yeast into 6 small jars. With careful management/ rotation I reckon I could keep this going for years. My thought process is by using a small jar to make a starter and then replenishing the jar from the starter before pitching into a brew I keep the yeast clean and unstressed.
That's exactly how I do it. I go through it here: ruclips.net/video/1Qr768FFcrk/видео.html
In this video I use yeast that has been stored for over 15months harvested that way. ruclips.net/video/Sy7v2Gga6dE/видео.html
Get some untreated wood and inoculate it like a norg;)
Nice experiment Dr. I Love the idea of just being able to brew on top of the previous batch and having one less thing to clean has got to be a bonus, Cheers :)
Yes that's a great bonus!
Ha ha...that's an extremely long experiment! Nice work!! Cheers for all your effort! 🍺🍺🍺👍😛
I'm so glad it's over!
Appreciate the effort you put in to your videos Doc, cheers and thanks for sharing
Thanks Keith much appreciated. Cheers!
Homebrewing exelence! Well done.
Thanks!
Very interesting video, I’ve repitched yeast slurry many times and never had any issues but never as many times as you with the same strain, definitely saves money too! , cool experiment, cheers dr Hans and get it in yaaaa!
Thanks buddy!
Thank you for all the great videos! I was wondering about your chest freezer with all the kegs and small diameter tubing. How do you keep the carbonation level and still pull a nice pour on all those kegs? I have trouble with this dealing with 1 or 2 kegs. Do you have any advice on how to keep your beers in service reliable as far as serving goes? Thanks again man! Cheers!
21 reuses without washing? That's super impressive! At least now I know it's possible to get a couple years of monthly brews by washing and reusing!
It works until it dosent anymore :D
it's very interesting how long that last before you saw yucky sidenotes. I've just started saving my yeast and I use the jar method first using some clean water and separating the trub and then use a funnel separator, I like to keep to same beer styles with the washed yeast and I keep everything sanitised and clean of airbourne bacteria because I'm not using a sealed and pressurised system. I have been using the same yeast and have increased the amount of yeast I have over 3 months by more than 8 times just by using a starter with the washed yeast and then cleaning that batch and so on. I've got a few yeast strains stored and I have spend minimal dollars. A lot of them are from dried yeast. I tried it and it works opposed to what many people say. I also have a few commercial strains from bottle fermented brews which work really well and seem to keep well. It takes time of course but it saves a lot of money too.
I harvest from my starters!
cool video. I keep yeast going until I get an infection and it really doesn't happen often. Also occasionally collect some yeast along the way as insurance to go back to.
Who needs a magic stick? you made a magic bucket (fermenter). Lol
Sometimes it feels just like that. ruclips.net/video/dt_kQtdj_Qs/видео.html
Cool experiment for sure, but sounds like a lot of maintenance to keep it up for a whole year. Great stuff. Cheers!
Not much maintenance at all actually. So glad the experiment is over though.
I usually use a non conical fermenter, do you think it works?
I don't brew as many time as you, do you think it's better to remove the yeast from fermenter,"wash" the yeast, and use them multiple time ? please let me know, HOMEBREW MASTER !
It will definitely work. But maybe not go on as long as I did in this experiment. Even with a bucket you could brew back to back pitching on the yeast cake. I wouldn't do beers with dry hopping. But...I havent done any testing regarding that yet.
What a long run. And by the way, I dont think it is a stupid thing to explore what you can do. But wow that fermenter is $$$ :-) Nice video too.
Yes it was interesting to see how long I really could continue.
I have US-05 strain I've used for about 15 batches now. I think it tastes better than the dry pack for sure.
Cool!
I use us05 and repitch fresh slurry from a newly emptied fermenter. It takes off within a hour or so, usually do four brews in a row. I make a starter when I start a new cycle so the yeast is ready to go with no lag time and happy fermenting. =)
Great video DrHans,
Can I ask of you to talk about your picnic tap system here and where can I find the flow reducers?
I have yet to solve mine over foaming issues. Hope to gain some insights from you, thanks in advance!
Thanks! I’m using a thin hose 3/16" (3,2 inner x 4,8 mm outer). Does that help?
@@DrHansBrewery Thanks for the fast reply, do you happen to have a link on the connectors that you used? seems like some size tubing form the quick connect to 3/16. the white plastic "stuff"
@@oapchian this is the reducer I'm using amzn.to/2IRlKKX
“Just about freezing for you Fahrenheit guys” 🤣🤣🤣
Quick converting 😅
It sounds like he says “Foreignheit” which I hope was intended, thats hilarious!
32.9, to be more precise. "Just about freezing" is right.
Nice exbeeriment there! The fact that your off flavor faded with cold lagering and the beer taken off the yeast cake could indicate that you have some autolysis going on. Maybe there was some old yeast stuck to the wall of the fermentosaurus that finally started to break apart.
Yes maybe. Hard to know exactly. Cheers!
Grunge in BACK! Dr. Hans all new Pencillin brewday. Cheers!
Cheers buddy!
Fascinating, thanks Doc.
Thanks Clive, glad you liked it. It was a long experiment. Glad it's over!
@DrHans Brewery how many liters of beer do you brew every year? If you listen to Spotify and "Hembryggning Halleluja" I think they say that after four batches a lager yeast can start to alter and change the taste.
Cracking video again cheers
Cheers buddy!
Well, at least it keeps the light out
Hahahaha yes! Cant believe I didn't say that. 🤣
one question, can the beer oxidize if we add fully oxygenated wort ? as some of beer is left over in the yeast
good video Doc. reused four times. it would be more if I brewed as often as you. cheers
I like to brew 🤣
Nice wideo! ;)
Thanks Patrik!
Nice one Hans. What about dry hop residues - if you did that? Any issues due to that?
I didn't dry hop or added anything else to the fermenter than wort. A bit boring . But it was one of the prices for this experiment.
Also interested in this. would be cool to see you do a version where you use hops, maybe lightly like in a pale ale. Loved the video!
Wow Doc I would not have had the guts to do that kind of experiment. Well done sir I found this very interesting. Seems you have a lot of work on cleaning that fermenter but I am sure you will have it sorted quickly.
Its clean know and new worth in it!
How do you transfer new wort into the fermenter? Do you just take the lid off the fermenter and pour the new wort in? That's how I do it but I've only reused the same yeast three times (because of wanting to make lager instead of ale)
Yes just like that!
This was interesting!!!!
Glad you liked it!
What if you made a coffee stout but replaced ALL roasted grains with coffee??
What is the inner diameter and length of your keg lines? I'm having trouble with mine. I only serve foam...
3/16" 3.3mm length 1.5-2meter.
@@DrHansBrewery the marrowest my LHBS supplies are 6.5mm. I got a 6mm from ebay, but I can't get any narrower than that to connect with my disconnects.
Alex easy just use a beer line calculator. Mine was about 3 metres. www.kegerators.com/beer-line-calculator/
3 time max but will try longer next time
Yes, three time max, stay with it. Yeast becomes senile. Homebrew info about yeast harvesting is poor. A home brewer does not have the means or knowledge to harvest yeast successfully. Yeast collected from home brew comes from wort that isn't clean, it is unstable, lacks in yeast nutrients and it is chemically imbalanced.
@@michaeljames3509 - I have been pitching the same colony of 34/70 for 13 months. I always pitch biotin at the last 5 minutes of the boil for each new batch. I am very careful about sanitizing my yeast jars. After transferring to a keg or secondary, I wash my yeast cake with clean water, let the layers stratify, and decant. My beers come out absolutely fantastic. I don't know if my colony will last *forever,* but your claim that three is the max, and "a home brewer does not have the means or knowledge to harvest yeast successfully"... I mean... are you joking? In this very video, Dr. Hanz said he repitched for 18 ~ 21 generations before he noticed anything, and that's about where I'm at too, so what are you basing your max of three on? Serious question - are you a microbiologist, a commercial brewer, or a yeast expert? I assume nothing. You may know way more than me, but my experience contradicts your claim.
RIP beer. Long videos are fine Doc keep em coming!
Thanks buddy. Get a lot of comments on other forums that my videos are to long and that I'm waisting peoples time. So it's good to hear. You cant please em all. Glad you like my videos. Cheers!
Too long? Stuff 'em, what about those who want to sit on the couch and watch beer talk instead of the nightly news?
Still watching, but love your vids mate! You have reminded me of how much fun screwing around with yeast can be :)
The real question is, are there any beers which would benefit from the mutations which occured over the multiple generations
How many times have you reused yeast?
I bought two packs of 34/70 in February of 2018, and I still use that colony today. I guess it has been repitched between 12 and 18 times. Not sure. I'm on my fourth or fifth generation of US-05, and my second generation of S-23.
DrHans Brewery I tried bottom harvesting with wlp007. It went south on batch 3, or south.. the bitter i made tasted like Saison.. but this was years ago, bet the yeast turned bad in between batches due to oxygen ingress. Anyway - that's my story, nowadays i brew maybe 10 batches/year so always new yeast for me. Cheers Dr!
Have only done "whiskey" mashes, 3 runs with the same yeast. Worked great taste better then most commercial..
I miss the smell of fermenting,... wish I had the time and resources to perfect my great grandfathers(1900's) recipe. I enjoyed your video, thanks.
I make a starter and save some and pitch the rest, I keep doing it over and over again..so I only buy a strain of yeast once.
Last year I reused US-05 around 15 times.
Each generation was dryer and stronger in alkohol.
I stopped when my SG was 0.999
Can`t listen to the extreme swenglish
Suburban Pjokk I get that. No worries. Thanks for giving it a go though. Cheers!
