I'm brewing an imperial stout this weekend with expected OG 1.113. I was planning to pitch 2 re-hydrated packets of Nottingham Ale Yeast. I can't get a clear answer on whether this will be enough - all the different yeast pitch calculators provide different answers. A buddy of mine just brewed an imperial stout with 2 packets of Nottingham and got 75% attenuation for 12.2% abv; however, brewer's friend calculator says I need 4-5 packets. Anyone have any similar experiences?
Alternatively, I've got a packet of White Labs California Ale Yeast and could make a 4-liter starter...
