Most ale yeast strains will attenuation from 65-80% as an average. To get the specific details, consult the yeast manufacturer's website, which will tell you the average attenuation for the strain you are using.
My OG was 1033 (ideal was 1036) and on the instructions it says that P1 takes 7 days. I took a reading on day 5: 1012; Day 6: 1012 and then technically tomorrow will be my last day so ill pull a reading.
However it says that the Ale FG should reach 1006 so therefore I am still off.
If tomorrow the reading is the same (1012) that means it has been at a constant for 3 days therefore is the fermentation ready even though the FG is higher then it should be?
