Definitely I think it requires a lower temp than s05. The instructions I heard over and over at one time were "Nottingham just rips through anything and is clean, its so easy, same as s05" etc, and I'm sure that it would have been fermenting likely around 65F. Also could have been an old packet
Is there a difference between BRY97 and s05?
Anyway, I'm not going to risk it on nottingham, got s05.. again.
