if use use good yeast i.e. safale it will always work. always.
Crap. Wish I had seen this hours ago - just brewed today - and when I "proofed" the yeast - nothing. I figured it was just too cool - and pitched anyway.
How long should I give it beo=fore pitching the emergency sachet of US05 I keep on hand - or could I just go ahead and bite the bullet and pitch it - should the Nottingham be ok, just slow - will the two be OK together?

The Notty probably isn't "infected" as much as "dead", but if the yeast didn't proof, you probably have your answer as to when to pitch: as soon as possible so other bugs don't take over. The problem might also be with their emulsifier or whatever they use to "foam" the yeast. Mine just stayed in whole intact pellets.
Classified as Saccharomyces cerevisiae.
-- A top fermenting yeast.
-- The typical analysis of the active dried strain:
-- Percent solids 93%95%
-- Living yeast cells 􀀪 5 x 109 per gram of dry yeast
-- Wild yeast < 1 per 106 yeast cells (Lysine method)*
-- Bacteria < 1 per 106 yeast cells*
Finished product is released to the market only after passing a rigorous series of tests.
*According to ASBC and EBC methods of analysis.
I'd be curious too about what others are experiencing as far as off flavours. I will probably taste tomorrow if there's no krausen to determine if the batch is sour or vinegary. It sure smelled like it after only 24 hours... I probably won't bottle and risk infecting all my tubing and plastic equipment if it is that bad.
The S-05 hasn't really took off yet either: wimpy bubbles and no froth or kausen, even though I ramped the temperature to 20 Celcius in the brew room and threw a blanket on my carboy.
I have never smelled anything like it.
None of these are spot on (except for maybe the band aid) but here is how I would describe the infection.
medicinal
band-aid
sour
sulferous
plastic
rubbery
Even after 12 hours I was getting inklings of this developing.
In all honesty, I think you're describing an infection or a batch that has been fermented at temps that are too high, which has nothing to do with the yeast pack.
I've had two batches of this Notty batch that was bad. It took 72 hours to take off with a well oxygenated wort. The off flavors that were associated with the batch were yeasty. That flavor dissipated over time. The last batch was consumed at one month of conditioning and was off for the two weeks that it took to drink. The other batch (BM's Centennial Blond) that I brewed with this bad lot, only took about five weeks+ to loose the flavor.
None of the flavors could be described as:
"medicinal
band-aid
sour
sulferous
plastic
rubbery"
Fermentation temps were good and there doesnt seem to be a lot of people reporting the same off flavours so the source of the problem probably inst the packet. These off flavours are consistent with pernicious brett. So it is looking more likely that a struggling ferment got infected by brett early on allowing the yeast an opportunity to build a huge population in our brew space (which was seeing a fair bit of activity and in various stages) and despite sanitation measures still exists. It is possible/likely that since the initial infection every subsequent ferment that has been slow to take off has been infected by this ambient population.
Just in passing - I was in my LHBS today and was advised while I was browsing the yeasts that there was no Nottingham to be had, that it had all be recalled.
I'll confirm that. I work part time at my LHBS and we received a letter from one of our wholesalers that informed us that Nottingham lot 1080961099V was being recalled. Oddly we haven't yet received anything from the two other wholesalers we use, which means that not every LHBS me be aware of this yet.
