My attenuation sucks! I have noticed that when I use Safale S-05 I get 73%-77%. But when I use a Wyeast Activator smack pack, I am only getting 63%-65%. What am I doing wrong? What can I do to better it? I do not make starters for either yeast and I do not re-hydrate the S-05. My efficeincy is 74%-76% and my SG and OG come out right where they should, but my FG is always high with a smack pack. I also control my fermentation temps so I know it's not too hot or too cold. Any suggestions?
