    Imagine you brew a batch of Vienna lager and split it into two. One half goes into a keg with yeast left over from a previous batch. No yeast harvesting or cleaning, just dump it right in. The other half? It goes into a clean keg with a fresh packet of the same yeast. Can you actually tell the difference between these two beers after fermentation? We put this to the test with 20 participants. Are these beers perceptibly different? Let’s find out.

    I have been pitching on the 34/70 yeast cake for years; I time my fermentations 2 weeks apart, keg and pour off about 2/3 of the yeast cake to prevent overpitching, dump the new batch on top, ferment at ROOM temperature and continue. I have done this up to 20 times in sequence without any off flavors or other nonsense. Great video, Martin, thanks and Cheers!

    I pressure ferment in kegs and usually plan to do 3 or 4 consecutive weeks of brewing, making progressively darker/stronger batches. I'll start with a new pack of yeast, they use the cake for the next few brews. I transfer out of the fermentor while the grain is mashing, then pour the new wort on top. I like saving a few bucks on yeast, but I LOVE not having to clean the kegs.

    I've used yeast cakes many times in the past! Now that I use the Fermzilla All Rounders I do closed transfers off of the yeast cake and pour my next brew right on top. I've never done more than 3 but have been tempted to! I'm a huge fan of the method as it is super simple and saves tons of time and money!

  • @tctruffin

    When I brewed on a more consistent schedule, I would very often reuse yeast from batch to batch. However, I never just dumped the new batch into the previous, unwashed fermenter. After racking the brew off the yeast, I'd collect a mason jar full of the yeast cake (sanitized jar, of course). After washing and sanitizing the fermenter (a plastic bucket), I'd fill with the new wort and pitch the reserved yeast. Never once had any issues. I got up to 8 batches from one packet of yeast (Wyeast 1056) before I decided to get some fresh yeast. There was no reason for the change other than I felt like I was pressing my luck.

    Just completed 3 generations/batches of Czech Lager (pale, amber, dark) using this method with my Anvil Bucket. Timing worked out perfectly where I closed transfer/kegged the previous batch during the 90 minute boil of the next beer, chilled to the low 60sF and fermentation was started before I finished cleaning up from the brew day. Can't say I detect flavor/aroma differences probably due to the different recipes, but definitely no adverse results or off flavors. Also, the song is perfectly goofy 🍻

    I have a dedicated lager pressure fermenter. I have reused the yeast cake for several beers over 2 years. I think of it as one big starter instead of having to spend lots of money on multiple packs of lager yeast. It produces the best lagers I have ever made

  • @michaelczernicki2249
    @michaelczernicki2249 Před 29 dny +2

    I've done several sequential fermentations on the same yeast cake, essentially using the first batch as a 5 gallon starter for the following one. This has given me great success and I've never run into off flavors or other defects caused by the process. Running my first version of making the same beer in sequence now and it will be fun to see if my experience is similar to what was presented here.

  • @stuartlay4565
    @stuartlay4565 Před měsícem +5

    I use a version of this method...I brew a batch using fresh yeast, ferment in my converted Sabco half barrel keg, and then keg to cronies. All transfers are done with CO2, so I never have to open the fermenter or a freshly sanitized cornie. The day after kegging, I brew another batch, usually a different recipe, and then transfer to the fermenter with the yeast cake. I find that second batch starts more rapidly, ferments more vigorously and finishes with a lower FG than the initial batch on fresh yeast. And both beers turn out great and taste wonderful. This cuts my yeast bill in half and is a great motivator to brew more often.

    • @rickyjayalexander
      @rickyjayalexander Před měsícem +2

      This is similar to my approach. I tend to ferment with clean yeasts, like us-05 or 34/70, and will often dump a batch right on top of the previous yeast cake. I'm not worried about opening my fermenter to get the wort in there, I like re-introducing some oxygen to the yeast anyway.

    I'm on my 12th generation of yeast cake and haven't noticed any of flavours yet. I ferment under 0.5b pressure and at 10C for a week, then raise to 15c for a week. The wort usually starts heavy fermentation after a few hours only. I intend to just keep doing this method until I taste of flavours. I've a few bottles of each batch. Planning comparing them at some point. Thanks for the great content. Keep up the great work 👍

    I might be giving this method a shot. I'm making a hefeweisen for my next batch. After that's gone, I was thinking I'd pour some apple juice in there and ferment it low to really push the clove character. I think that would work quite well in a cider

    I've utilized this approach numerous times to good effect. For practical reasons however, I generally prefer to just recycle the yeast slurry. Had a Kveik Voss run for nearly three years, fermenting countless batches in that time before I eventually started over with a fresh yeast. I can't say I was aware of any obvious changes with those countless reuses... impossible to say really.

    What I notice is reduced lag time and faster fermentation with the reptiches of the Weinstephaner lager strain. I've taken this up to 3 generations I'm the fermzilla conical. The first 2 generations are great! The third generation tends to hang around and takes a good bit of rousing to get into the yeast vessel at the bottom of the fermenter. Time really doesn't appear to improve this as it is rousing. I'll be brewing and fermenting with McGuires Irish Pub house yeast (proprietary strain) under pressure to see how it performs in a pressurized environment. I do know this repitches very well. Thanks for all the work you've put into this series Martin!

    It's not quite the same, but I use a fresh yeast cake from a conical Fermenter. I do a trub dump day 3/4 of fermentation and then a yeast dump after emptying the Fermenter, before pitching the wort onto what's left. Works a treat.
    I usually do "lighter" beers first, with the least hops/speciality grains. It's superb for high gravity beers.

    If you pitched the same amount of yeast cells, this experiment would be valid. I would've pitched 1/3 or 1/4 of the yeast cake. With 05-yeast, ive been doing this and reused more than 20 times. No issues, but I also keg, brew and pitch the very same day.
    Thanks for a great show. I'm watching every video.

  • @KevinMeyer
    @KevinMeyer Před měsícem

    I have re-pitched on top of yeast cakes for years, typically I dump and start over after the third generation or so. Echo what others have said about the reduced lag time and ferments more vigorously and finishes with a lower FG with the re-ptiches . . . so there's some real pluses to doing this method, but you can very quickly overpitch. Then again, I'm usually making IPAs with lots of hop character, so the resulting beer is usually hard to distinguish if it had fresh or not. Fantastic video and always entertaining - thanks Martin!

    My state's first craft brewery. Started off with ringwood yeast. Since then the original founders all split off and created their own breweries, using the same yeast. You can now brew the same beer at 5 different breweries and they all come out different as the yeast is no longer ringwood as about every 5th or so generation the yeast mutates and they've been separated so long they're like long lost relatives of each other.

  • @sgoadhouse

    For a recent brew, I tried pitching on a yeast cake for the first time. I did a Czech Premium Pale Lager with fresh Imperial Urkel. I kept the beer on the yeast cake until brew day thinking it would help keep the yeast fresh (probably didn't matter). However, I cold crashed to transfer the beer off, of course, but now the yeast cake is 36F. I cannot chill my wort much below 70F. That is an enormous temperature differential. So I transferred the beer early on brew day and then let the kegmenter with the yeast warm up during brew day. I got the yeast to around 60F and the wort to 68F when I transferred the wort to the kegmenter with yeast cake. Still not the greatest differential but at the edge of acceptable. I next chilled the wort in my fermentation chamber to get it from 68F down to 55F for fermentation, which it did just before the lag phase ended. This second beer was a Czech Amber Lager so that the yeast is still appropriate and has the same hops (Saaz) as the first recipe. At first, I thought the Amber had a ton of esters, and it might have, but as the Amber has been lagering, the esters are far less pronounced. So far, it is an enjoyable beer. I sent it to NHC, so we will see what the judges think of it. I plan to do one more beer with this yeast cake, naturally a Czech Dark lager.

    I do very similar in my small scale system. I do however don't have a microscope to see if the yeast is healthy, but I do taste the yeast cake. My theory is if it tastes good then it will ferment good.
    The other difference is I put my wort in the keg at 170˚F, and the next day I drop in the cake when the temps are ideal. Your show is one of the best on the tube!

    Your floating dip tube tubing is too long, that’s why you couldn’t get the last of the beer out. Cut the tubing shorter so the filter only just reaches the bottom, but the tubing doesn’t, and you will get almost all of the beer out

  • @grahamhawes7089
    @grahamhawes7089 Před měsícem

    A little dip in Starsan makes it very easy to slip the tubing over the shortened dip tube. I also like to slip two stainless washers over the tube to ensure that there’s some weight holding the tip underneath the liquid, otherwise you can suck air. Lastly, I usually purge the tube by blowing some CO2 through it before transferring… though maybe with the filter attachment that isn’t necessary.

    Awesome episode! Totally expected a non-significant result on this one. I've pitched direct to the yeast cake before with great results but never done a side by side with fresh.

    I've never poured a fresh batch onto the yeast cake from a previous batch. I don't consider that best practice as there will be hop trubb and proteinous matter as well as yeast which may influence the flavour negatively. I have often washed harvested yeast from the bottom of a fermenter and reused it with excellent results. When I add it to a starter of boiled and cooled DME it takes off like a rocket. Very healthy and happy yeast!

  • @timpolster
    @timpolster Před měsícem

    The success of this method really depends upon how clean your wort is going to the fermenter. Many homebrewers do not take steps for really clear wort going to the fermenter. So a process change/improvement might be needed to get rid of the majority of trub/break material if you want success reusing yeast directly. Keeping the yeast in a CO2 (oxygen free) environment is the best way to store yeast. So the method is technically sound but dependent on the brewer's sanitation & wort separation skills.

    Hi Martin :D
    I have 4 SS fermenters (3x50 mini uni and 1x58l kegmenter), and i regularly brew 42l in the 50l ones, and 50l in the 58l ones.
    I brew 3 times, one with fresh (dry) yiest, and two times more where i just "dump" on top.
    I _usually_ brew a new batch between 14 days and 2 months after the last one, with an average of about 5 weeks i guesstimate.
    I could possibly brew a 4th or 5th batch, but the headspace will start to get VERY low at this point i think, so its 3 max for me.
    Im not sure how much of a difference i can detect, and what i prefer the most, but i mostly think of it as a "huge starter", and it usually "take off like a rocket", and start to ferment within hours.
    This are also a "light lager" style "drinking alot of" style beer. (Think Heineken, Carlsberg, Tuborg or similar).
    18c for 5 days, and then a rampup to 25c for another 5 days, and then i turn of the heat, and then i just "lager" in the same tank. This is done in a norwegian cellar, so its basicly between 4 and 10c year round.
    S-23 Yiest, and under about 15-20psi/1-1,5 bar of preassure.
    Saves ALOT on yiest, and also ALOT less cleaning to do.
    For the first batch i add:
    10g of yiest per 10l of beer.
    6g/10l of DAP
    For all batches:
    whirlflock at 15min
    2 packets of dry bread yiest at 15min, as thats also an excilent yiest nutrient.
    The first batch is ran over a kegland wort spreader (KL33640) to get a better airation.
    It would be very interesting if you re-did the experiment, but with fresher yiest then 5months or whatever. Or even did a triple-split, with fresh, 2months and 5 or 6 months, and see how that went.
    Cheers!

    Float it 2.0 hooks up outside the keg, more expensive but worth it in my opinion.

    I have thought of doing something similar...but just brewing a batch 2 weeks after a previous batch and just putting the wort on top of the old yeast...so transferring to a keg and immediately putting new wort on it

    Interesting experiment. There's obviouly a massive over pitch in the yeast cake beer. You might find that the results would be much closer if you pitched at a similar rate in each beer. Rinsing the yeast prior to use would be ideal but even lazy brewers would get decent results by simply discarding a portion of the yeast cake prior to pitching

    I have done this with beer and mead. I seemed fine with the beer. The mead final gravity ended up being 1.030 so it was more sweet than I’d like, even though I had some peppers in the second batch. 🤷‍♂️ More experiments are being done.

    I wonder how results would differ based on yeast strain/beer style.

    I only add my floating dip tube to a keg lid with a post. Such a pain to add the floating dip tube to a post on the actual keg.

    Does they use the fermenter keg as a server keg too? I mean without transfering the beer to a clean one

    Can't help but wonder about the impact of any remaining CTZ characteristics in the yeast cake version. Perhaps a variant on this experiment using a yeast from a beer hopped with Magnum and Tettnang, like a German pilsner or helles, would lessen the impact of that variable?

    I've done three lagers on the same yeast cake. I thought they were good but timing brews can get difficult

    Hello brewology what is you made a malt mix,, mixed half with ale yeast and the other one with lager yeast what would be the difference in taste...🍺🍺🍺🍺🍺

    I'm wondering if there would be a big enough difference with taste with comparing pilsner malt vs 2 row, a friend once told me there's the same 🤔 so maybe you could make two batches and see if there's a big enough difference or not

    As a homebrewer who uses dry yeast exclusively, why do others use liquid yeast? Is there any perceptible benefit?

  • @jcinsaniac
    @jcinsaniac Před měsícem

    How different is this practice from using a foeder? Seems to me the real difference might be that perhaps more yeast is suspended in the foeder wort than just a yeast cake - but there's definitely a yeast cake that will build up in a foeder.

  • @vikramjitsingh4538
    @vikramjitsingh4538 Před měsícem

    it's ok on a homebrew level......but no sane brewer will put wort on top of a yeast cake on a commercial scale, the risk is too high.........but great video........in essence it's about pure yeast culture and the beer u can get with it......cheers.......another great video

    Ask Dino at White Street how many times he uses the yeast. He has a set amount of pitches, but I've forgotten the number. Also, I wonder if it's not the yeast cake, but the age of the cake. You said that the cake was 3 months old. What about a fresh one? 2 weeks old?

  • @gustag
    @gustag Před měsícem

    I only reuse the same yeast for 3 batches and always increasing the alcohol content of the beers. E.g.: bitter ale; cream ale; american IPA

    they never do isolated blind tests? lots of chances to influence the tests

  • @freehlr
    @freehlr Před měsícem

    Using an entire yeast cake is something you can get away with for one, maybe two batches, but there will eventually be autolysis. You'd be pitching an amount of cells well above max cell density. Too many cells for the food available = a lot of dead cells. And the surviving cells will get tired because they did not have the opportunity to divide. Cell division is important for optimum fermentation performance. This is why recommended pitching rates are far lower than max cell density.

    Should’ve shaken the keg before you started the video to clean all the crud that’s been sitting inside of it

  • @gregbush8573
    @gregbush8573 Před měsícem

    thought off the bat that this would be a pretty obvious test, definitely should have closer results if your "used" yeast is fresher, cone to cone style rather than sitting at serving pressure for months autolyzing itself and stacking genetic drift toward survival in that environment
