jackgym Posted July 12, 2022 Share Posted July 12, 2022 It's a bit cool on the Sunshine Coast with the result that my ale is fermenting at around 16.5 deg. Will that affect the outcome, I know it's better at 18deg. but I don't have a heat pad. Using US-05 yeast. Link to comment Share on other sites More sharing options...
Classic Brewing Co Posted July 12, 2022 Share Posted July 12, 2022 The experts reckon as below but below is a link from the manufacturer. Key Figures For Safale US-05 Fermentation Temperature: ideally 18-28°C https://www.bing.com/ck/a?!&&p=b55ffb39d60eae63d214a1f7e62f0b8d81b02222c026ca7f573d370edff0fc84JmltdHM9MTY1NzYxMjcwOCZpZ3VpZD1jMzZmOTU3Yy0zZTM5LTRmMmUtYTQxYy0yMDc3MDRmNGU3OTgmaW5zaWQ9NTI1Mw&ptn=3&fclid=69ecdd40-01b8-11ed-9b68-9dbab1be8df0&u=a1aHR0cHM6Ly9mZXJtZW50aXMuY29tL2VuL3Byb2R1Y3Qvc2FmYWxlLXVzLTA1Lw&ntb=1 1 Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted July 12, 2022 Share Posted July 12, 2022 It'll still work, probably a bit slower than it would at 18 though. Possibly not as clean flavoured. 1 Link to comment Share on other sites More sharing options...
jackgym Posted July 12, 2022 Author Share Posted July 12, 2022 Luckily the initial ferment (3 or 4 days) was close to 18 while generating it's own heat but after that it was struggling to get to 16.5. Hoping that will still result in good beer. Link to comment Share on other sites More sharing options...
Otto Von Blotto Posted July 12, 2022 Share Posted July 12, 2022 That would be because it slowed down near the end of the fermentation. It's not ideal having the temperature drop off like that but there's not a lot you can do without some way to keep it warm. It's more likely than not that it'll still be good beer though 1 Link to comment Share on other sites More sharing options...

Hoppy81 Posted July 12, 2022 Share Posted July 12, 2022 US05 is fine at that temp, Check out LittleJohn on Youtube, he often brews at 15°c with US05. 1 Link to comment Share on other sites More sharing options...

I would agree Hoppy, I have been brewing a lot of Ales with US-05 over the last few years, a lot of them at ambient temperatures - the average daily temp was always around 18-20c but in the cooler months the night time temperature would have gone down sometimes to 16-17c & not once did I notice any off flavours. I realise a consistent temperature is ideal but it's a fairly versatile yeast. I have an Ale with US-05 going ATM but controlled at 22c. So I should be able to compare them. 1 Link to comment Share on other sites More sharing options...
ozdevil Posted July 13, 2022 Share Posted July 13, 2022 I wouldnt go much lower then 15°c but what you may find going below the disered reccomendation is it will just take a bit longer to ferment out and get started 1 Link to comment Share on other sites More sharing options...

I found it surpassed US05 in several ways - temperature range being one of them. i.e. 10ºC - 22ºC which makes it a great choice for the Winter months. This is also beneficial when it comes to bottle carbonation in the cooler months. Nottingham also has a relatively short lag phase, a clean and neutral profile, high-attenuating with greater levels of flocculation compared to US05. Might be worth considering for future Winter brews... 6 1 Link to comment Share on other sites More sharing options...

Can I take it that you mean that Bottle carbonation will happen in cooler conditions, say down to 15c (or lower)? That would be a big help for me in winter. 1 Link to comment Share on other sites More sharing options...

Yes Nottingham will carb up your bottles at 15 degrees no problem. I tend to leave them for 4 weeks if I can and haven’t had a problem. And it flocks down well too. 2 Link to comment Share on other sites More sharing options...
