Little by little I have the clearest ideas David. The LHBS are going to hate this video for their drop in sales of yeast lol :) Thank you very much for everything you contribute to the homebrewer community
Ive been brewing for 2 years now all grain, once a month, and never used the same yeast twice, I so wish I had seen this video when i started because id have an awesome collection by now!!
I greatly appreciate this video. I am stunned at the process. A decade of storage is phenomenal. I am subscribed, sir! Greetings from Little Rock, Arkansas, USA.
Your videos really help, teach, motivate and excite us in our brew adventures. Just wanted to stop and say thanks for everything you’ve shared. Your content is the best of the best IMO and you should be very proud!!! 🍻 👍🏼 👍🏼
I don’t know if you read this, I hope so. I recently emptied a fermenting jar of about 12 liters in wine. Which sat in the corner of the house for as long as I live here now. ( 7 years ) Thinking it all been converted to vinegar by now. But surprisingly it was still carbonated and smelled really good. I scoped a little of the yeast out the bottle. Giving it some sugar and marmite it started fermenting just a day later. It’s not just to say I tried this. Cause I forgot about that jar. But this little experiment just shows how resilient yeast is.
This looks like a game changer for me! I’ve been repitching yeast slurry with good results. Looking at yeast banking for longer term storage. Can’t wait to get on with drying my yeast.
Hi David, cool video as usual :) I tried to dry my first batch of yeast. I put about 1,5dl of yeast-slurry in a glass flatbottom pan. Next I placed the pan in my herbs dehydrater at 30c, Nice and crispy after just 4,5 hours.
Again very interesting. I have a dehydrator whic will also proof bread dough. I would expect that to be not to hot to kill the yeast. In conjunction with your other video on Top Cropping I will try some more specialised yeasts for my general Cooking Bitter. Ha! I said to a pub Landlord ages ago "Pint of Cooking please" and he was most offended. Didn't seem to realise that you do not cook with anything you would not drink. Many thanks.
@@DavidHeathHomebrew hello. When you placed the yeast slurry on wax paper and placed it in the small plastic container. How did you sanitize the wax paper? Or does it need to ne sanitized if you are just regularly drying it in the plastic? Thank you.
Thank you David for this interesting video again! Will try this out soon - just started to use Kveik and wanna keepsome of them in the drying method! Cheers! Robert
I would suggest as low a temperature as possible. Some use an oven on the lowest setting with the door open, I prefer a short period in a dehydrator on the lowest setting.
Have you tried to re-use the yeast you dried yet? If so what process did you follow? What viability is the dried yeast? Do you make a starter or just rehydrate?
I add the full liquid yeast to a jar. Add it to thr fridge till it all drops down. Take a teaspoon worth for the pitch. Then wash the rest for the next 2-3 brews.
Great video DH. Since you have been responding to recent comments on a 6yr old video can we presume you haven't changed your method on this? Would you do anything different now? And have you tried it with a non-kveik yeast? Thanks and cheers!
So what do you do after? Do u mix DME with water and pitch yeast for a starter? Is it possible to multiply yeast by pitching store-packed dry yeast in a DME/water starter? Thanks :)
Old video, I know, but here's my process through 5 "generations" of Skare kveick: Top crop directly to a sheet of sanitized wax paper. No straining yeast from liquid at all. Set that wax paper on a table in my brewery. Point a USB -powered fan at the yeast to dry it as soon as possible (my theory is that drying it quickly stands less of a chance of wild fungus making a home). Scrape it all into a container 24 hours later. Critiques welcomed!
@@DavidHeathHomebrew I should have asked you in my last question David but I've just started a hefe with Wyeast 3068 Weihenstepaner. Some say you should take the bad stuff of around 24hrs then take the yeast at 48hrs, what doyou recommend?
Very informative. My fermentation happened so rapidly that i missed my opportunity to top crop. Can I collect some slurry from the bottom of the fermenter to dry?
You can but now you will need to follow a more time consuming process. Here is a pointer to make that easier:- ruclips.net/video/1HVensTsRXc/видео.html
Great video, just one question tho. You say at the end that everything is sanitized. Do you sanitize the baking paper?? If so how do you achieve it?? Thanks for the amazing content and knowledge you are sharing with us all.
Thank you :) Yes, it is vital to sanitise everything that comes into contact with the yeast. I use star san in a spray bottle to sanitise the paper. I leave this for some minutes and then pick the paper up to drain the liquid. You can apply the wet yeast directly then.
Hello David! I got my hands in some kveik so I definitively will try to dry it. The question is how do you desinfect de baking paper? And my problem is where to find a "dry place" in Belgium😁Cheers
Hi David, thank you for a super interesting video! I'm definitely going to try this. It does throw up a few questions for a newbie such as myself ... 1. drying the yeast at home. I expect this is dependent on the humidity factor. For example, here in Portugal winters are very humid. Other countries suffer humid summers. Does it have to be really dry to do this successfully? 2. does room temperature come into effect or any temp is ok? 3. When you have your finished yeast and ready to pitch, does it need need to be re-hydrated or maybe even need a yeast starter any other process? Or simply can I chuck it straight in (if so, does it need crushing first)? Thanks again for so many useful videos!
ESL KidStuff I would suggest drying it in a heated or a reasonable temperature room. It would dry anywhere but temps will factor the time it takes. I would pitch it in some wort after mash out that has been cooled to pitching temps. Shake the container during the boil and chill process.
Hi Brian, six months seems the max to me on average. Having said that if you know you will not use it for some months it is best to dry it. I have a full guide here:- ruclips.net/video/fzcnyyvWAYA/видео.html
Would it work if i bought a pack of dry brewers yeast and then activated it and cultured it to make more, and then dried it again? Would the final product be exactly the same as the packet i originally bought?
Sure you can do that. Over time the formulation could change over a number of generations but this will be much slower for single strains than multiple strain mixes.
I have just scooped out the yeast cake from a kölsch after coldcrash and bottling. I've dried it according to your recipe above and put it in the freezer in a ziplocker bag. How much of these dry flakes do I need to add to my next kölsch (how many grams for 20 litres 1.060 OG beer)? Also how do I check if the yeast is good or bad before I use it and how many times would you recommend to reuse a given yeast before buying a new one?
Do you think you could freeze dry the yeast? My wife has a freeze dryer, I was thinking about having her freeze dry some yeast for me but I would like your input. Thanks
Hi David. Just got done watching your top cropping video and this one popped up. I haven't read every comment so you may have already answered this question. Can you dry ale and lager yeasts also? I thought it was only kveik yeasts. Thanks david
Hi David, at which point in fermentation should a yeast be top cropped? Specifically using Omega Hothead and not sure if to wait till the end or do it whilst the krausen is still active.
Wait, what? *You can freeze the dry yeast?* Have you tried this? Do you just chuck the vial with the dried yeast in the freezer or is there anything else you need to do to prevent yeast cells from bursting? Does freezing affect yeast viability?
You sure can, it will prolong its life. The best way is to store it in a container with a minimal amount of air. Wrapping it in cling film securely or vacuum sealing it. Let it return back to regular temps before using. No need to add anything.
@@DavidHeathHomebrew Awesome, thanks. I'll try it on my next batch. Is there a reason for recommending top cropping instead of just using the yeast cake left after the primary?
@@DavidHeathHomebrew That is how the universe goes... but hey, oh well!! Still, its unheard of. I wonder if its controlled somehow for some reason. NOT that you don't deserve it =)
@@DavidHeathHomebrew looks like i missed the window, the whole thing went from 1.060 to below 1.020 in less than 48 hours. at 60 hour mark it doesnt bubble at all, beast of a yeast :)

7 years later, and still one of the very few videos on this topic haha. Question, what temp can you dry out yeast before they start to Die off
I would suggest as low a temperature as possible. Some use an oven on the lowest setting with the door open, I prefer a short period in a dehydrator on the lowest setting.
That's easy enough... Sure worth a try. Thanks and cheers =)
Drunkinone sure is :) Glad you liked it.
Have you tried to re-use the yeast you dried yet? If so what process did you follow? What viability is the dried yeast? Do you make a starter or just rehydrate?
Sorry I have just noticed that this is unanswered! Yes, I have been using this process for quite years now. I just rehydrate in wort :)
@@DavidHeathHomebrew so you open a vial and simply add one tsp of dried yeast on the fermenter during transfer? as simple as it? TY :)
I add the full liquid yeast to a jar. Add it to thr fridge till it all drops down. Take a teaspoon worth for the pitch. Then wash the rest for the next 2-3 brews.
Brilliant. Cheers.

So what do you do after? Do u mix DME with water and pitch yeast for a starter? Is it possible to multiply yeast by pitching store-packed dry yeast in a DME/water starter? Thanks :)
Hi Luke. No need to make a starter, just pitch :) If you want to built up the yeast to more cells then by all means make a starter :)
Thanks man
Thanks :)
Excuse me if you have already covered this but how do you then revive/restart the dry yeast? How do you establish a cell count? Cheers

That sounds good Jim. Assuming that you have nothing flying around that can land in it. I have my box protection with this in mind.
Another great video David, thank you. Would you have to make a starter with that amount of dried yeast before re-using in a brew?

@vincelafore4281 cheers Vince 🍻🍻🍻
Hi David, at which point in fermentation should a yeast be top cropped? Specifically using Omega Hothead and not sure if to wait till the end or do it whilst the krausen is still active.
For kveik I top crop after 24 hrs of pitching. You want high krausen for any top crop.
I'm new to brewing do you need to do a starter with this.
Yeast degrades gradually in this state. You should be using a starter to improve yeast health if this is not used in the first week or so.
Dear David .... Have ever tried to dry comercial yeasts instead off kveiks ?
Sure. It works very well :)
What if you placed salt or calcium chloride in the box as a desiccant?
+Colorado Clyde Ive never heard of this being done. Most dry naturally , it could work well though.
How would you go about reusing the yeast after it has been dried? Just like normal
Yes, totally :)
Thanks David, but what about bottom harvesting after fermentation and drying?
.
Does this process work with the Lallemand dry Kveik yeast?
Yes :)
Wait, what? *You can freeze the dry yeast?* Have you tried this? Do you just chuck the vial with the dried yeast in the freezer or is there anything else you need to do to prevent yeast cells from bursting? Does freezing affect yeast viability?

Great. Yes, yeast that is top cropped is in prime health where as bottom is tired and compromised.
Awesome David ! can this method be used to dry only Kveik, or could it be used to other strains like US-05 or W34/70 ?

Could a dehydrator be used?
Yes. I use one myself. I made an updated version of this not so long ago on this channel.
Can it be done with all liquid yeasts?
Sure, no problem.
after the yeast is dried does it have to be re-hydrated IOT use it in a beer? If so, what is the best way to do this?
I always rehydrate in wort. It is used much like dried sachet yeast, just no real need to crumble it as much.
@@DavidHeathHomebrew I thought you pitched dried yeast directly or is that what you mean?
I do, it is rehydrated in the wort :)
