Spursman Posted January 8, 2023 Share Posted January 8, 2023 My current brew in the fermenter is Coopers Canadian Blonde with Morgans Premium Lager yeast at 13°. About to do a d-rest then cold crash. Question is - is it OK to bulk prime in fv then harvest the yeast from the slurry? I am bit concerned that the priming sugar might be somewhat retained in the slurry and kick it off again. Wasn't planning on washing the yeast but maybe I should? 1 Link to comment Share on other sites More sharing options...
ben 10 Posted January 8, 2023 Share Posted January 8, 2023 Pretty sure there will be residual sugar in the yeast cake 1 Link to comment Share on other sites More sharing options...

Spursman Posted January 9, 2023 Author Share Posted January 9, 2023 Okay I agree with you both. If I were to immediately refrigerate the slurry would that do the trick or do you think that washing is a safer alternative? 1 Link to comment Share on other sites More sharing options...

For an ale yeast I would say yes. 2 or 3c and its likely to stay dormant and not continue fermenting the sugar. For a lager yeast which is what you are using it's likely to keep slowly fermenting. I have seen this with lager slurries before. However it will be slow. So if you are using it in a weeks time for example a degassing every 2 days or so till you use it and you will be fine. 2 Link to comment Share on other sites More sharing options...

I read this AFTER I screwed the lid on tight on one of my jars. Luckily when it was proving difficult to undo, I put it in the sink. Erupted everywhere when I eventually got the lid off. 1 Link to comment Share on other sites More sharing options...
Tone boy Posted January 10, 2023 Share Posted January 10, 2023 I just cover my yeast slurry jars with sanitized happy wrap and a rubber band. Much better than worrying about lids and explosions and works great. 2 1 Link to comment Share on other sites More sharing options...

It's the old school opaque Coopers one so using this method I can see what's going on (or not) inside. Works a treat although I have a love/hate relationship with Glad wrap. Frigging stuff never wants to tear off the roll and when it finally does it ends up sticking itself together! 1 3 Link to comment Share on other sites More sharing options...

Then the box starts breaking up & you can hardly keep the stuff in the box to use the cutter risking amputation. 2 1 Link to comment Share on other sites More sharing options...
Uhtred Of Beddanburg Posted January 11, 2023 Share Posted January 11, 2023 @Tone boy I just use the jar lid but have found a few times even when cold in fridge the lid will bulge. Mainly with lager yeast but strange because would think its dormant with no activity. I don't bulk prime with sugar before collect so cant see how would do this should have eaten all sugars in brew Link to comment Share on other sites More sharing options...

I think the yeast is dormant but perhaps the yeast is still working away very slowly even when cold. 2 1 Link to comment Share on other sites More sharing options...

So I may have trouble with cling wrap. But I do look for bulge and de gas if needed. 3 Link to comment Share on other sites More sharing options...

Most of the sugar will end up in your stubbies. Assuming it was disolved as it should have been very little will be in the slurry. In any case as suggeted just leave it in the fridge in a sterile jar with glad wrap. It will be fine. Not sure how long it wll keep though. Perhaps some one will chime in with that info. 1 Link to comment Share on other sites More sharing options...
Graculus Posted January 13, 2023 Share Posted January 13, 2023 (edited) I didn't have time earlier in the week, but I found a pic of the yeast I screwed the lid on. Looking at that now I realise I could have marketed that as some fancy green sludge health food. Edited January 13, 2023 by Graculus 7 Link to comment Share on other sites More sharing options...

Spursman Posted January 13, 2023 Author Share Posted January 13, 2023 Decided not to bulk prime. Rinsed the yeast cake a couple of times then pitched it into a fresh Canadian Blonde with BE2 wort at 22° immediately knocked it back to 18°. Checked after 3 hours and its going bonkers. Dropped to 15° overnight. Just checked again, krausen subsided a lot. Dropped to 12° which is recommended temp for this yeast (Morgans Premium lager yeast). Gotta say I was a bit nervous about trying to re pitch but it seems to be going well. Thanks to everyone who provided great advice - much appreciated. 3 Link to comment Share on other sites More sharing options...

Then if I don't it gets moved anyway so would rather leave it if not used again fast enough. In the drinks fridge it can only fit in the door and I don't like it moving all the time when gets opened. The missus used to complain with me moving stuff around to put it where it could stand. Now she probably just suffers in silence, good enough for me 2 Link to comment Share on other sites More sharing options...

I get to keep my yeast harvests in the "family Fridge" at the back of the top shelf along with half a dozen beer glasses. A bit like @Uhtred Of Beddanburg, when I tell the family I am brewing on the weekend I just get "the look". 2 7 Link to comment Share on other sites More sharing options...

My wife hates the smell of a brew in progress and the consequent "look" is all too familiar. She's Chinese and occasioanly 'cooks' up the most horrendous traditional Chinese medicine concotions on the stove, the fumes of which often leave me gagging, but being the gentleman I am, there is no corresponding "look". Oh the irony! Edited January 23, 2023 by BlackSands 1 4 Link to comment Share on other sites More sharing options...

If you have a spare FV, you can syphon the beer into that one and then bulk prime. That way you can harvest the slurry without any worries. It's a little more cleaning work but at least you can enjoy the benefits of bulk priming and reuse the yeast. 3 Link to comment Share on other sites More sharing options...
Oldbloke Posted January 23, 2023 Share Posted January 23, 2023 Yeh, 190g will dissolve 1ltr. I add the additional 1ltr to cool it down a bit. Yes I like good head. Link to comment Share on other sites More sharing options...
