Stuck Stout

[Vizen2]

Fellow brewers, the more I brew the more questions I have, funny that. I have a Mangrove Jack’s roasted stout in the fermentor and it seems to have stuck at 1.020, after dry hopping a week ago the SG hasn’t moved. I gave it a good stir 2 days ago and pushed the temp up to 24C, this morning still no air lock activity. I was considering adding a rehydrated packet of yeast, should I add 5 or 10 g, would adding extra yeast have a detrimental effect either way. Any thoughts on how to rescue this, my first stuck brew.
Thanks

If you have brewed a high ABV stout like an imperial you may find the SG is not so much stuck as finished dependant on a number of things including the yeast you have used.

Cheers, it started at 1.051 so not too high, I’ve just checked it and after the stir it’s dropped to 1.018ish. If I did add extra yeast and it didn’t drop any further would it harm the beer/taste?

If the SG is still coming down I would leave it. Some brews just take a long time. But if you do decide to add more yeast it will either get your beer down a few more points or it wont, but in my view is very unlikely to affect the taste, since all the yeast will eventually drop out, and its also a stout with a lot going on.

Thanks, I’ll give it another week and take a view, if it’s down to 1.010ish I’ll bottle if not I’ll chuck in more yeast and watch this space. Cheers

I've waited a month for Young's IPA to finish...X 2!

Ditto the above!

One of the longest brew I have ever had was an Oatmeal Stout which took from 14th December to 25th January to fall from 1.060 down to 1.011 (i.e. 6.43%)

Patience is a wonderful thing to develop and brewing is one of the best activities to practice the art!

Still stuck so earlier today I added 10g of rehydrated yeast, seems to have started fermenting again, will give it a week and see where the SG has got to. Watch this space.
Thanks again for all your input.
