Cassius Posted December 27, 2019 Share Posted December 27, 2019 Apologies if this has been asked before but I'm struggling to find the right keywords to search for past threads. I think I've got a good idea of what I need to do to reactivate the coopers commercial from bottles of coopers green, but what if i don't want to drink 6 in a setting? Can I just add the sediment to the larger bottle over a few days and then "re-activate"? Or should I pour all the beers into another vessel or vessels and do all the sediment at once, as if I've drunk them all in one sitting? TIA.

Malter White Posted December 27, 2019 Share Posted December 27, 2019 I think you should be ok to accumulate the sediment over a few days. Make sure you sanitise your storage vessel. I'd also be inclined to use a smaller storage vessel so the yeast is exposed to less oxygen and then transfer into your harvesting bottle once you've gathered all your sediment. Naturally, keep the lid closed and in the fridge until you're ready to harvest. 1 1 Link to comment Share on other sites More sharing options...
Shamus O'Sean Posted December 27, 2019 Share Posted December 27, 2019 I left the dregs in the Coopers greens and just covered with glad wrap. I figured they would be reasonably sanitised in the bottle. At least enough to last for a day or two until I had six bottles. This approach worked fine. 2 1 Link to comment Share on other sites More sharing options...
Cassius Posted December 28, 2019 Author Share Posted December 28, 2019 Thanks very much. As it turns out I was out last night so didn't end up starting the 6-pack. With the heat today it wouldn't surprise me if I got through all 6 haha. 1 1 Link to comment Share on other sites More sharing options...
Aussiekraut Posted December 28, 2019 Share Posted December 28, 2019 That's a good question. I've been down south across the border yesterday and picked up a 12pack of Coopers Green from Aldi (@$16.95!!!), mostly for the yeast but also for the beer I prefer drinking the 6 bottles needed over a couple of days, so there is room for other beers as well 2 Link to comment Share on other sites More sharing options...

Well it's been an hour and I'm on my third. Now I'm just glad I put some of my Session Ale in the fridge haha. 1 Link to comment Share on other sites More sharing options...
Cassius Posted January 2, 2020 Author Share Posted January 2, 2020 Well it's now been over 5 days and there's no activity on top of the liquid. There is, however, a huge amount of pressure in the 1.25l soda water bottle I used. When I twisted the cap to release a bit of pressure a large amount of foam formed and rose to the cap before I twisted it closed. The escaping gas had a strong beer/yeast smell. Any ideas?

Naughty Corner Brewing Posted January 3, 2020 Share Posted January 3, 2020 It’s probably done. You’ve essentially fermented under pressure which prevents a krausen forming, however letting the CO2 out will make it puff up like a chemical reaction. Between now and when you want to pitch it, you’ll want to do that a lot! Let as much CO2 out as you can without wearing it. 1 Link to comment Share on other sites More sharing options...

Sooner the better I imagine? And is there a concrete way for me to confirm it's active before I go and ruin 23L worth of other ingredients? Thanks again. 2 Link to comment Share on other sites More sharing options...

If that is not possible, you could put it in the fridge for several weeks and it should still be fine to pitch into a wort. I harvested Coopers Commercial slurry from a previous brew into a jar and into the fridge on 1 November. I am just reinvigorating it over the last couple of days for a Coopers XPA I am doing today.

Cassius Posted January 7, 2020 Author Share Posted January 7, 2020 Quick update to say that I pitched the reactivated yeast a couple of days ago, with my fingers crossed. Within about 12 hours there was a very nice krausen formed, a bit different to any I've seen in my 6 or so previous brews. About one inch thick with very fine bubbles; almost like a layer of mashed potato. Delicious. 3 Link to comment Share on other sites More sharing options...
Malter White Posted July 29, 2020 Share Posted July 29, 2020 I appreciate this is an old thread but I'm kind of proud of myself at the moment and needed to tell the world, it appears I've been successful at reactivating the Coopers commercial ale yeast. My first attempt didn't work. My krausen and wort appearance was as Cassius described. Bottled yesterday and sampled. Tasted very much like the real thing. Go me! 4 Link to comment Share on other sites More sharing options...
UncleStavvy Posted July 29, 2020 Share Posted July 29, 2020 (edited) I'll consider myself slightly biased, but if you have issues drinking 6 stubbies in a sitting might I suggest an alternative hobby to home brewing? It's an amazing yeast however and well worth the effort. Harvested 6 dark ale stubbies in March and still using the yeast in multiple brews Edited July 29, 2020 by UncleStavvy 2 Link to comment Share on other sites More sharing options...

Harvested 6 dark ale stubbies in March and still using the yeast in multiple brews Tone is hard to convey through text so I'll be an optimist and assume this is a light-hearted dig. While I don't really feel the need to defend my drinking habits, maybe an explanation will preempt any future digs: some nights, particularly on weekends, I'll have 8-10 beers. Some nights I feel like having 1 or 2 beers, usually with dinner. To forestall my inevitable decline into alcoholism, I have made a rule that I don't drink at all Mon-Wed. With that out of the way, great job @MUZZY. 2 1 Link to comment Share on other sites More sharing options...
Shamus O'Sean Posted July 30, 2020 Share Posted July 30, 2020 Hi @Cassius, Your numbers look similar to my commitment. Six beers on a school night is a bit much for me. But come the weekend, watch out. Good job @MUZZY, it sounds like you have had success this time around. I am drinking two beers done with the same harvested Coopers Commercial. One at 18°C and one at 24°C. The 24°C is supposed to produce a fruitier outcome. I cannot really pick a difference between the two. I also did a side-by-side last night with an Original Pale Ale (can). The original had a more noticeable fruitiness. Maybe next time I use it I will have to up the temperature a bit more? 1 1 Link to comment Share on other sites More sharing options...

It means I can enjoy more things without worrying they don't taste right. 1 Link to comment Share on other sites More sharing options...

The 24°C is supposed to produce a fruitier outcome. I cannot really pick a difference between the two. The higher ferment temp brew will generally throw a more prominent banana-like ester. The ester is an aroma, rather than something imparted into the beer flavour. At least from what I read with some yeast strains, a fruitier outcome (a derived flavour) often happens at the lower end of ferment temps rather than a higher temp with numerous strains. The ability to promote the ester profile is also affected by yeast cell pitching rate. Much like a wheat beer, under-pitching & fermenting at an elevated temp will help to encourage this. Just my 20 cents, Lusty. Link to comment Share on other sites More sharing options...

Thanks Lusty, Both brews have a definite banana aroma, or ester. More banana than a Coopers Original Pale in a side-by-side test. The Pale has a citrus/spice that my brews do not. Mine were also half Wheat Malt Extract which might enhance the banana a bit. Link to comment Share on other sites More sharing options...
Beerlust Posted July 31, 2020 Share Posted July 31, 2020 The Chinook you used in the Pale Ale can add a light spicy tone. The citrus would be that combined with the Cascade & Columbus. In the Summer time, the Fruit Salad Ale using Amarillo & Cascade along with the CCA banana ester produces a very cleverly constructed & enjoyable beer. Cheers & good brewing, Lusty. 2 Link to comment Share on other sites More sharing options...
Tom Charter Posted September 2, 2020 Share Posted September 2, 2020 Hi all, maybe a really dumb question but haven’t seen it mentioned anywhere else and I’m about to have my first go at reactivating coopers commercial. everything I’ve seen Is based on a 6 pack but I’m a longneck man, surely there’s no difference in going with 3 longnecks is there? cheers! 1 Link to comment Share on other sites More sharing options...

That's what I did once. There did not seem to be a difference. Is there actually a difference? I do not know. The logic says, probably not. 1 Link to comment Share on other sites More sharing options...
loafing_about Posted September 3, 2020 Share Posted September 3, 2020 I've just started a culture using the hazy IPA. Dregs of 2 cans last night into a dextrose mix in a sterilised bottle and already showing good signs of activity tonight when I added dregs of 2 more cans with plenty of bubbles and fizz. Will let it go for a few days then if all good step it up to use when I brew the vintage ale recipe of the month. I wasn't sure how it would go with high alcohol content of the hazy but seems pretty lively! A bit excited, a bit nervous, to go to the vintage ale after only 2 brews following a 15 year pause but the first brew went well. It was a very simple Sierra Nevada clone (brewmart) with some cascade hops. Tasting good after 3 weeks in the bottle but in hindsight bottled too early and it's over carbonated. Second brew a simple straight pale is still in fermenter. 3 Link to comment Share on other sites More sharing options...
