Leo53 Posted November 20, 2018 Share Posted November 20, 2018 Recently purchased a pale ale tin on the 14 Nov 18, yeast had a julien date of 28917. The yeast did not appear to activate and I threw out brew after 7 days. Could the old yeast have been the issue. I did every thing as per instructions, although the wort temp was 27/28 when I pitched. Kept receipt, from an SA food chain. Should I ask for refund?

PB2 Posted November 20, 2018 Share Posted November 20, 2018 You should have checked the Specific Gravity of the brew to be certain that the yeast was not fermenting.

Smashed Crabs Posted November 20, 2018 Share Posted November 20, 2018 Yes I'm wondering how you concluded it wasn't fermenting ? Iv had many a brew not bubble at the air lock or form a solid Krausen but finish all the same. Link to comment Share on other sites More sharing options...
Lab Cat Posted November 20, 2018 Share Posted November 20, 2018 I don't think you had enough to go on. I've had a beer or 2 that showed virtually no foam activity at all and still brewed. The Hydrometer is the method to find out what's happening, or not. Link to comment Share on other sites More sharing options...
Leo53 Posted November 20, 2018 Author Share Posted November 20, 2018 I did check sg (1040 ish), I used coopers enhance 2 and the sg had not changed in the 5 days it was in fv. I guess I put it down to newbee mistake. Thanks all for feedback. Next batch bubbling away nicely! Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted November 20, 2018 Share Posted November 20, 2018 The yeast was still in date, but given no SG change it sounds like it was cactus for some reason Link to comment Share on other sites More sharing options...

If yeast sits on a shelf in supermarket for 12 months at varying temps and no stock control the yeast would surely detiorate. I understand yeast best kept in fridge at low temp. Learning experience: scrutinise the best before date! Thanks for your interest - brew on. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted November 21, 2018 Share Posted November 21, 2018 Dry yeast are reasonably hardy but depending on conditions it is possible that they died, or at least were significantly compromised. I think in this case that is what happened, otherwise it would have fermented. In such instances, usually a second lot of yeast are pitched if the first pitch does nothing after 2 or 3 days, but of course you would have to have some on hand or buy extra to do this.

Leo53 Posted November 21, 2018 Author Share Posted November 21, 2018 Thanks Otto, I brewed back in the 90tees, yeast was always the bain of my existance. If anything I should have learnt not to buy from supermarkets, no stock control, no shelf life! Although, same supermarket, same coopers pale ale, same shelf and this one is going gang busters. It could have been the type 2 enhancer was off after 12 months on shelf. Gotta let it ho! Cheers..... Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted November 21, 2018 Share Posted November 21, 2018 Not likely, sugar doesn't go off, especially in sealed containers. If the yeast was in good shape it would have fermented it. Link to comment Share on other sites More sharing options...
