I have a question regarding attenuation percentages on extract brewing. I have made two batches so far and am only getting rates of 65-68%. My first started at 1.069 and finished at 1.021 and I used us-04 yeast. My second batch strated at 1.074 and finished at 1.024 and I used us-05 yeast. I have a chiller and pitched my yeast around 65ish degrees and splashed my wort back and forth to get oxyen in it both times. My first batch had active fermentation signs within 12 hours and the second didnt sart showing signs until 24 hours. I did not use a starter either time. I am expecting to get rate of 75- 80%. Thoughts?
