I did a partial mash recipe for an Oatmeal Stout on Friday and totally blanked on taking my OG reading... Couple too many homebrews on brew day I suppose. Anyways, I took a reading 40 hours into fermentation and found the SG at 1.030. It seemed to be fairly vigorous fermentation so it makes sense that it might have been that low. I was looking for an OG of 1.070, does this current value seem to be possible after that amount of time? Thanks.
