Lazy yeast???

[rob171171]

Hi
I've used a Coopers Brewmaster India Pale Ale 1.7kg + 1Kg of spray dried malt extract (light) to 2 lites of boling wtaer, mixed and topped up to standard 23 litres of water.
I pitched my Safale US-05 Dry Ale yeast at 27C.
Nada
Yilch
Nothing

Have I gone crazy and missed any key components as no fermentation is happening, 24hours+ later

It can take up to 3 days for it to multiply enough to start visually fermenting. As long as the yeast was still good. Not to mention,27C is a bit high for that yeast. US-05's upper limit is 75F (23C). Cool it down,& it may rouse itself.

wow really? all (4) brews Ive done up to know kick off styraight away. Maybe this is not such a lazy yeast after all and more of a late developer???

 

[unionrdr]

The temp's too high for that yeast. Most ales should be brewed at 20C or lower,not upper 20's. Too warm. Some yeasts,like cooper's ale yeast are more forgiving. Some aren't,& go dormant.

 

[rob171171]

so what should I do, try and put it in cooler surroundings?

 

[unionrdr]

That,or do the swamp cooler & frozen water bottle thing. Or a shallow pan of water with a tee shirt over it to wick the water up with a fan on it.

Thanks man. I'm in Ireland so thanks to our really crap summer at the moment cooling it down should not pose much of a problem!! Its in shed!

Cool. It's been downright chilly today,but it's been blazing hot every afternoon. Just got my new batch in primary,second day,BLAM! 93F! Damn. This weather is totally wack this year.

the yeast will probably produce plenty of off flavors, but it should be werry happy at high temps
Guess it took a while to start this time(it happens), or it might be done already while your back was turned

 

[rob171171]

Ok Im confused now! WHat is the optimusm temp fot this Safale US-05 yeast?
One says less than 20C and another says uts ok at 27C...

I have it sitting at about 18C currently!

Please advise

You might look up the Fermentis (maker of Safale US-05) website, check out the specs for this yeast.

Thanks--Yes I should have done this initially!

Sprinkle the dry yeast in 10 times its own weight of sterile water or wort at 27C ± 3C (80F ± 6F). Once the expected weight of dry yeast is reconstituted into cream by this method (this takes about 15 to 30 minutes), maintain a gentle stirring for another 30 minutes. Then pitch the resultant cream into the fermentation vessel.
Alternatively, pitch dry yeast

Recommended fermentation temperature: 15C – 24C (59-75F).
