Any harm in adding yeast?

[Painter]

My latest batch had:
6.6lbs Light LME
1lb Light DME (both Briess)
1Lb crystal malt (60L)
1Lb brown malt
1Lb carafa II malt
1 vial White Labs P001 yeast

I didn't get an OG because I dropped my hydrometer as I was about to take the reading.

The fermentation has stopped.

Right now the gravity is 1.021, which I think is a bit on the high side for bottling, though a person at my local shop said he thought it would be OK. Would it hurt to add more yeast to see if that would get the fermentation going again, or should I just go ahead and bottle?

I would take a few more reading over the next 3 or 4 days and see if it has stabilized if it has its probably done. Adding yeast would really not reduce the FG that much because if the gravity has stabilized the vast majority of the fermentable sugars have been consumed. Its not uncommon for extract brews to finish right around the 1.020 range. Adding fresh yeast might get you a few more points but I doubt you would really detect a difference in the overall taste.

Fresh yeast won't hurt anything but it probably wont do anything either. I'd just give it another week or two then bottle.

Also - if you haven't calibrated your hydrometer you might want to do that as well to verify your reading. But definitely you are looking for stability as well.

I doubt enough yeast is an issue. Leave it be for another week and see where you're at. You may still end with a highish FG, which is not uncommon with extract (plus a good amount of crystal malt in this recipe).

Try warming it up to 70° for a couple of days. Maybe your beer got too cold and your yeast went dormant. My $0.02... Try that. Most people have problems regulating their temperatures during fermentation.
