Hello, I brewed my first Imperial Stout back in October 2019, planning on serving it at my 60th, i achieved an OG of 1.105, with a target FG of 1.016 giving 10.61% ABV - i only managed to get the FG down to 1.040 so it was well under ABV and still a bit sweet, used 05 ale yeast (in hindsight this was not the best choice) - I have now barrel aged it for the past 7 months, i was hoping that it would lose some of the sweetness and some reading i had done indicated that the FG may improve while in the barrel - i have tried it today - very smooth but still too sweet and the FG has stayed the same - so, my question is - could i put it back in the fermentor? say using some high gravity yeast to kick off anther fermentation ? any thoughts would be great - I've got a month till i want to drink it at my 60th!
