Nottingham yeast not working

[ni9e]

I made a beer sat evening sprinkled dry nottingham yeast into the FV as normal @ 25c and as of noon today the yeasties showed no sign of life what so ever no bubbles on the surface and no co2 smell coming from the wort took a hydro reading it was still 1055 :wha: this has never happened to me before so I sprinkled on some s04 and sealed up the FV again.

But now thinking about it when the s04 kicks into life is there a possibility of it waking up the nottingham if so will there be any conflict with the two yeasts?

If the nottingham yeast stays dead will it cause any off flavours etc and last thing would it be best to transfer to secondry once finished to try to brop some of the excess yeast out before bottling as ive never pitched 2 pkts of yeast before.

IMO not IME:

There may be conflict but I would have thought all that would happen would be that one strain would dominate.

The first thing yeast does when it hits the wort after waking up is multiply, you probably won't end up with any more yeast at the end of fermentation having pitched two packets, especially if one was a dud. It might be worth transferring to secondary after 2 or 3 days fermentation just to get it off the spent yeast, I wouldn't bother.

Remembering responses to stuck/non-started kit questions it seems just pitching a second pack and treating as normal would be fine.

I have had a notty fail and after 3 days threw in So4 and of it went like a train. Beer was good.
