I recently brewed a surly furious clone with sg of 1.065 and it only went down to 1.020 sfter two weeks in primary. I made a 900ml starter with one vial using a stirplate. Pitched at 62 and raised over 5 days to 70.
Doesn't 67% attenuation seem kinda low? I mashed at 153 but maybe my thermometer is off? I calibrate it at freezing, but I've heard that calibrating closer to mash temps is better.
