> If it was CO2, how long would it continue at an aggressive rate?&nbsp; I know they say to measure OG but the beer is in a carboy and I am not all that keen about opening it up to measure. Someday, a conical will fix that.

Open it and measure…it’s no big deal.&nbsp; I’ve done it for years using a sanitized turkey baster.&nbsp; As I’ve often said, if you can’t take a gravity sample without screwing up your beer, maybe you should consider taking up knitting for a hobby!&nbsp; 😉
