Is anyone having issues hitting final gravity? I’ve been brewing all grain for about 6 years with cooler mash tun and batch sparge. I was always within a point or 2 from fg on the couple hundred brews I did over that time, some high, some low, most, spot on. Since getting the grainfather in the spring, all 6 brews I’ve done on it are always 5 points high on gravity, it’s scary how consistently high I am. Now I haven’t tested my hydrometer lately, but with the care I take of it and only using it for FG, makes me think it couldn’t have changed.
I do notice a residual sweetness on recipes I have re-brewed with the GF that wasn’t there with my old system. I have triple checked mash temps with Three thermometers I know are spot on and everything is in line. I’ve used different yeasts, different batches of grain and different mash temps. I guess the only variable I haven’t looked into is mash ph, because over 6 years in the past, it was never an issue.
Anyways just wondering if anyone has any thoughts. It’s not the end of the world and I can adjust recipes going forward, just odd how consistently off this is since switching to the GF.
Update to this. I decided to change one variable on my last brew, I went with a 90 minute mash, instead of my typical 60 minutes. Mashed at 148 for 90 minutes. I kegged that beer last night and did a FG check and it was spot on where it should be at 1.009. So yeah, not sure if my mash in is dropping the temp too far and not coming up fast enough in the center of the mash or what. I will check that next time, but for now, I'll stick with the 90 minute mash as it seemed to have worked to cure my issue.
