worry wort Posted March 8, 2022 Share Posted March 8, 2022 Hey brains trust, just had my first issue with 'vegemite beer'. Coopers Real Ale, 1.5kg malt extract and 200g Dextrose. After 6 days I took an SG reading, and I always sample the brew at each reading stage. No real off-aroma, but it had a definite vegemite taste. Bottled yesterday (10 days sg 1.010), took the lid off the fermenter and there was a sort of film of swollen brown 'things' on the top, which I took to be the affected yeast cells, so after researching here it all points to autolysis. I bottled anyway, but now wondering if the beer is ok to drink? 1 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted March 8, 2022 Share Posted March 8, 2022 It's probably safe but I'm not sure why you'd want to if it tastes like Vegemite 1 1 1 Link to comment Share on other sites More sharing options...
worry wort Posted March 9, 2022 Author Share Posted March 9, 2022 it wasn't overpowering, just a sort of 'here i am' taste, and as I have 8 batches going, by brews are usually 4-5 months before they're on centre stage, so I'm kind of hoping the aging process will 'soften' the taste, but just wasn't sure if there were any bad side-affects. I haven't read of any, but noone actually stated if they in fact saw it through 2nd fermentation to the point of drinking it. 1 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted March 9, 2022 Share Posted March 9, 2022 I don't think it's a flavour that ages out of beer given what causes it. It's your choice if you want to keep it but personally I'd have tipped it without even bottling it. I did that with a batch a couple of years ago that tasted off, no point suffering through something you don't like. 4 Link to comment Share on other sites More sharing options...

If you do, well done, I'd be lucky to have mine in the bottle for 4 weeks. 1 3 Link to comment Share on other sites More sharing options...

Give it 2 or 3 weeks in the bottle then taste it, then u will know whether to keep or chuck it. 3 Link to comment Share on other sites More sharing options...
Oldbloke Posted March 9, 2022 Share Posted March 9, 2022 autolysis, what causes that? 1 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted March 9, 2022 Share Posted March 9, 2022 35 minutes ago, oldbloke said: autolysis, what causes that? Yeast cells dying. The cell walls rupture and all the innards wind up in the beer. Hence why it is unlikely to age out. I once microwaved some yeast in order to do an experiment, the smell coming from that was horrid. If it tastes anything like that good luck drinking it 1 1 Link to comment Share on other sites More sharing options...

Quote Many causes may be cited for autolysis, not least simple old age. However, poor handling of yeast and beer will accelerate autolysis. Common examples are high temperatures, particularly above 25°C, or sudden changes in temperature at pitching or at chilling, and osmotic shock where yeast is pitched into high gravity worts. Some yeast strains may be inherently sensitive to conditions such as high alcohol, high carbonation, and high acidity and autolyse faster than others. In other conditions extensive re-pitching of yeast from batch to batch may create stress, as can the presence of contaminants including lactic acid bacteria and other yeast species. 1 Link to comment Share on other sites More sharing options...

Oldbloke Posted March 18, 2022 Share Posted March 18, 2022 I also have 8 batches. 4 or 5 months for me too. Also have 1 additional batch of stout. Could take over 12 months for me to drink that. Start drinking at about 6 Months, just have a couple of stubbies every now and again. 2 Link to comment Share on other sites More sharing options...
DavidM Posted March 18, 2022 Share Posted March 18, 2022 Well I tip my Glass (to often) to @worry wortand @Old bloke, my cupboard is full but apart from stout and a special brew, my session ale's don't last longer than 5 weeks. 2 1 Link to comment Share on other sites More sharing options...

worry wort Posted June 27, 2022 Author Share Posted June 27, 2022 Ok, so after 3+months in the bottle, I have worked my way to this batch, and its great. Good head retention, krausen lined glass, clear, no odour and good taste, so there you go, time solved the issue this time. 4 1 Link to comment Share on other sites More sharing options...
