I agree with you that unless you've got at least the makings of lab facilities, it's best not to go through more than 3 or 4 generations. This is especially true when you're using a dual yeast like RIngwood or Adnam's. But remember that every bottle of beer made with the original starter is a source of first generation yeast and it can be recultured in the same way that you did with the Proper Job bottles.guypettigrew wrote: ↑Thu Apr 29, 2021 8:05 amThis Saturday's brew will use a Proper Job yeast. This will be the fourth time it's been used since harvesting it from some bottles a couple of months ago.
The yeast is collected by scooping out about 1/2 litre of fermenting beer from the top of the FV 24-36 hours after pitching and when there is a good strong krausen. It's stored in the 'fridge, where a thin layer of yeast settles out, until needed. It's then woken up in 1 litre of malt extract at about 1.040.
How many times do you re-use your yeast? I've always thought 3 or 4 times is enough, given my extremely basic yeast collecting technique and facilities. Getting an infection and losing a batch of beer is not worth the risk.
How often do others renew their yeast?

Re: re using yeast
Thank you for your concern and nice of you to assume my beer is terrible
I didn't say it was a perfect way to capture, but that I have proved it works. Further it is not my only process.
Different folks different strokes.
Some consider dead yeast a good form of nutrition in a fermentation.

Re: re using yeast
FYI McMullan’s got a background working with yeast professionally, following some of his advice on starters improved my fermentations significantly.MashBag wrote:Thank you for your concern and nice of you to assume my beer is terrible

I would also advocate swapping beer with others too, most of the good brewers I know made a lot of improvements from others reviewing their beers and then getting to try others (both good, bad and indifferent).
I have been thinking about organising an annual JBK swap…..

But I then I remembered that I’m currently tasting/assessing beer from three different swaps and struggling to keep up and maintain a healthy level of drinking each week (even ignoring the ludicrous 14 units/week that HMG currently advise as a maximum). Timing, I suspect, will be of the essence!
On the topic of starters, I’d be interested to see McMullan’s advice.

Fermenting: pseudo “beyond the Firs” (Burnt mill beer clone), Geuze
Conditioning: English IPA/Bretted English IPA
Drinking: Sunshine Marmalade, Festbier, Helles Bock, Smokey lagery beer, Irish Export Stout, Orval clone, Impy stout, Duvel clone, Conestoga (American Barley wine), Dobbin 2 dark mild
Planning: Kozel dark (ish), Simmonds Bitter, Bitter, Citra PA and more!

Re: re using yeast
I suspect that would involve using a ring of plaited pieces of wood dipped into the beer at full ferment and then left hanging in a porch or over the door before using it to inoculate the next brew. This is the way things are done in Norway, I understand. Nothing like a bit of tradition!Cobnut wrote: ↑Wed May 05, 2021 10:34 amInitial response:f00b4r wrote: I have been thinking about organising an annual JBK swap…..

I am a qualified winemaker, and many years fermenting (aand rattling on about it) has taught me many things - every day the school day and there is always another way....and what are they doing with plaited wood in Norway

Check out Lars, If you haven't read his book already, I'd recommend it, it's really fascinating.One of the traditional ways of capturing and harvesting yeast is by making a rough wooden or plaited straw ring and dipping it into the brew to be covered in yeast and then dried in the open air. But it's also a story of survival at the edges of agriculture.
Professional experience of working with yeast? So has our baker! If you want a serious authority on yeast, this is the one: Yeast:the practical guide to beer fermentation by Chris White and Jamil Zainasheff. I think White Labs know what they're doing even if they are a pain in the butt with their irregular release of their Vaults strains.

Re: re using yeast
Think I have read it ... There have been a few. I measure my brewing library in feet.
FYI... It's not THE practice - it is A practise that I have proved, never said it was optimal. There is often more than one way.
There are brewers operating will all sorts of setups/constraints /budgets and this may suit one of them.

Re: re using yeast
Quite so. I'm not even going to say what I do for fear of being excommunicated and burnt at the stake, But having read White and Zainasheff, at least I know what I'm blissfully ignoring. For me, the absolute must is cleanliness, everything else is secondary. I mentioned traditional practice in Norway and Estonia and them there parts, in a sort of tongue in cheek way. BUT, if they can keep yeast going from generation to generation by letting it dry on a stick and then stirring it back into the beer then perhaps we're being a bit anal over our practices. I said in another post, and it wasn't a joke, that I preferred it when brewing was a branch of sorcery rather than a branch of science.MashBag wrote: ↑Thu May 06, 2021 6:53 amThink I have read it ...

Edit: Reference to letting a brown sticky mass dry on a stick and using the word "anal" in the same sentence conjures up some unfortunate images. yet I'm sure these fellows wouldn't keep making it if the beer were shite.

That was a very restrained reply Mcmullan. Probably too restrained for most to understand.

Yes indeed.
Yeast managed to survive and thrive long before we even invented the microscope

Re: re using yeast
I think the small conical fermenters have been a stunningly successful addition to the profits of the manufacturers and really increased clean up times and in 99% of cases made no difference whatsoever to the beer. Maybe even some chiropractors have seen a boost to their business.
Plastic, me too. One might even have a scratch somewhere
