You do not have to drink all six in one sitting. As I drink them, I empty most of each bottle into a glass. Leaving 2cm of beer in the bottle. I recap the bottle and put it back in the fridge. You can do this over 2 - 3 nights. Then do the yeast harvesting process once you have the six bottles ready. 2 1 1 Link to comment Share on other sites More sharing options...

Or else I just loose interest in doing the harvest. Then there is the time factor. I take about half an hour per stubby. So it takes me about 3 hours for the six bottles. This can be an issue. Especially on a school night. 2 Link to comment Share on other sites More sharing options...

That's how i usually do it. I also harvest yeast from PET longnecks and even use the "master" longneck to reactivate the yeast in. I dunno if the practise is advisable but I figure if the inside of the bottle was clean enough to house the beer it should be clean enough to grow the yeast as well. 2 Link to comment Share on other sites More sharing options...

You would like to think so, as I said in previous posts all I ever did was take some from the bottom of the FV & whack it in the Erlenmeyer Flask, cover & fridge it but I had never really worked out how much to put in the next brew. 2 Link to comment Share on other sites More sharing options...

I'm at a loss on how many actual yeast cells I've ever made when I've done it. I just mix it with one of either LDM, BE or dextrose (whichever I have on hand), preboiled cooled water and shake the bottle a few times a day. If it makes gas and smells nice I just dump it in the brew. No idea if I overpitch or underpitch but it's always made beer. 4 Link to comment Share on other sites More sharing options...

The few times I used re-used yeast I didn't add anything & it worked so buggered if I know. I will be using fresh yeast until I can work out the Yeast Stir Plate Uncle Al sent me. 2 Link to comment Share on other sites More sharing options...

NBillett09 Posted January 18, 2023 Author Share Posted January 18, 2023 I have another two questions, unrelated to each other: 1 - when bottling, are you supposed to chuck the bottle caps and use brand new ones every time you bottle a new beer, or can you re use the caps once cleaned and sanitized? 2 - when fermenting in a vessel, does it particularly matter what volume brew is in what total volume FV, particularly in relation to smaller brew in a bigger fermenter? ie the craft FV is obviously for smaller batches 8-10L give or take, but is there any detrimental effect for putting an 8-10L batch in the 23-30L FVs? 1 Link to comment Share on other sites More sharing options...

PET caps can be used many times over until they fail. Crown seals should be re-cycled and put in that bin if pry off is done to open them and new ones used each time. Twist off can be re-used up to a point on twist off bottles but they need a special twist sealing technique each time. 2. Nothing wrong with fermenting a small brew in a lager FV, only effect is more cleaning and sanitising to achieve the result. If you can live with that extra work then all good.

NBillett09 Posted January 25, 2023 Author Share Posted January 25, 2023 This Kolsch is at day 9 of fermentation, and it’s achieved the stable gravity of 1.012 which was the target, but my past brews had some very light bubbles on top at the end whereas this has what looks like a layer of trub sitting at the top? Will this layer drop to the bottom or has it not really finished fermentation yet perhaps? Also does the hop bag/sock usually float? I expected it to take on water and drop down but it has floated on top for a few days now. 3 Link to comment Share on other sites More sharing options...

Hi @NBillett09 from my experience depending on which yeast you used the krausen should drop back into the FV, there is a chance it could have stalled but that would depend on the temperature, you are displaying 18c. Regarding the Hops the bag can be waited down with a sanitised spoon, @Shamus O'Seanmay add to this. Cheers. The fermentation temperatures need to be 58 to 62 F (14.5 to 16.7 C), depending on yeast strain. The best options are Wyeast 2565 Kolsch and White Labs WLP029 German Ale/Kolsch yeasts that provide the low-ester profile and a desired dry finish. 2 Link to comment Share on other sites More sharing options...

The coopers recipe I'm following says to ferment at 18 so i have kept it between 18-18.5 the whole time, its the LalBrew Köln Kolsch yeast, this is what they say for this yeast on their website: In Lallemand’s Standard Conditions Wort at 20°C (68°F) LalBrew Köln™ yeast exhibits: Fermentation that can be completed in 7 days, a bit slower than most ale strains. This is perfectly characteristic of this strain. Medium to High Attenuation and Medium Flocculation Neutral to slightly fruity and estery flavor and aroma The optimal temperature range for LalBrew Köln™ yeast when producing This strain is POF Negative Traditional styles is 15 – 25°C (59 – 77°F) Lag phase can be longer compared to other ale strains, ranging from 24-36 hours Lag phase, total fermentation time, attenuation and flavor are dependent on pitch rate, yeast handling, fermentation temperature and nutritional quality of the wort. Ah the spoon idea is good, ill try that next time. Edited January 25, 2023 by NBillett09 2 Link to comment Share on other sites More sharing options...

If not, you could just give the FV some gentle but repetitive taps with your stirring spoon to dislodge the Krausen and encourage it to fall. The hop bag usually floats if you do not have it weighed down. And sometimes even if you do. I use 20-40 sanitised glass marbles to weigh down my hop bags. I usually remove my dry hops after three days in the FV. I use powder-free food handling gloves. I put the gloves on and give them two lots of squirts with sanitiser, rubbing at each stage. When I pull the hop bag I give it a nice squeeze with my gloved hands to get as much hoppy goodness into the brew as I can. If you leave them for too long you can get grassy flavours in the beer. You do not have to do the squeeze of goodness if you do not want to. Give your hands a bit of sanitiser and just pull out the hop bag, let it drip for a bit then discard. 4 1 Link to comment Share on other sites More sharing options...
Mackbrew Posted December 7, 2023 Share Posted December 7, 2023 Hi all, I started brewing/experimenting at the beginning of the year but got sidetracked with life (wish I was a teenager - I’d know everything, have an answer for everyone, and have it all worked out!). Anyway, I have spent some of the time productively researching the brewing game, and I’ve been checking the forums occasionally to search subject matters - thanks people. Nothing beats being able to learn from others’ experiences. Brew wise, I just tasted the Coopers Irish Stout I had planned to put down earlier in the year. It was great, but obviously needs a bit longer in the bottle. I tried to improve on my Cerveza efforts, and I just bottled a batch using Coopers Cerveza, BE3 and dry hopped with 25g of Citra. Just slow steps for me in the experimenting game, but upon bottling I was pleased with the smell, colour and taste. Just now I’ve put down a Coopers Pale ale, with harvested commercial yeast (yeah, go me!) Im quite excited by the experiment and this forum has helped me see that small steps are good. My next batch will be a Coopers celebration ale. I have good memories of having one before heading overseas in 2016, so I thought I’d give that a go. I do want to give a Saison a try too. Anyways, looking forward to a better year ahead and hope I can contribute something to the forum. Thanks for listening. 7 Link to comment Share on other sites More sharing options...

It took me a couple of years before I had the confidence to start harvesting yeast and experimenting with hops etc. Onya, Mack. 5 Link to comment Share on other sites More sharing options...
