A gravity mystery?

OG 1.072 FG 1012

did you check it every hour? it might have just slowed?

 

[NoCornOrRice]

I checked it every 24 hours and so at 48, and 72 hours from pitching it stayed at 1028. I did calibrate my hydrometer with water and it showed correctly.

Is the actual FG 1.012 or is that the estimated? What was your mash temp? Is the gravity still dropping or is it still at 1.028?

1012 was actual FG. Mash temp was 152F maintained by an electric HERMS system.
