I brewed an oatmeal stout that started at 1.055...now it has been hovering just above 1.030 for 3 days now...do i have a stuck ferment or is it done??

[bonjour]

Not enough details to really give an answer.  Recipe, Mash profile, ferment (wort) temps, all your process details.

That said,  most "stuck" ferments are done ferments.

YEEEAAA...GOOD POINT

So, can you give us some more details? Your attenuation is terrible and there is most certainly a problem. I would advise against putting that beer in bottles.

If you try everything else and can't get it going again, try some Beano. It's saved a few beers for me back during my extract days. Others may knock this suggestion, but I'll bet most of them have never tried it.

What yeast did you use? Maybe it flocced out too early? The first thing I'd do is try rousing the yeast.

That and raise the temp a couple of degrees if you have temp control. Helped me finish a sweet stout that quit after 3 days.

I've tried it a few times to try to "salvage" beers.  I don't think there was a single one where the Beano made it better than it would have been if I'd just left it alone.

In my opinion, a 1.030 beer is a syrupy dumper. Anything to help it should be tried and I doubt that Beano will bring something that high too low, but if it does, you're no worse off.

Before taking any extreme measures, you might want to pull a sample and dump a packet of Nottingham in it.  If there is any fermentable sugar left, that huge slug of yeast will take care of it in a short time and you can check the gravity to see where it ended up and that should be your target for the rest of the batch.

I always check my hydrometer calibration before I do anything drastic.

That was my first thought too, but surely it can't be off that much. Yeast, picthing temps, ingredients, fermentation temps, we need all that info to help you. For a beer to underattenuate by that much is very unusual. As a guess, possibly your fermentation temp crashed or your yeast was old and unhealthy. Maybe you used 50% oats and didn;t provide enough enzymes to break them down. Just impossible to say at this vantage point, only guess.

That comment just rang a bell!  Is the OP even measuring with a hydrometer?  If he's using a refractometer and not performing the 'alcohol correction', that could explain what he's seeing.

[majorvices]

good point

[davidgzach]

Or maybe the OP is not measuring a 60F sample with the hydrometer?  Need to know the temp of the primary too.
