I have been brewing a Cherry Stout since December, letting it sit in primary for a month. Its FG was 1.13.
I decided to forgo the cherry extract and use real cherries. I blended up 48 oz. of sour cherries in light syrup, and 48 oz. of frozen dark sweet cherries and added to secondary. I then racked the beer. I checked a few days later
1-8-13 add cherries to secondary, rack beer on top
1-10-13 SG = 1.018
1-13-13 SG = 1.010
1-28-13 SG = 1.010
After three weeks with the cherries, I racked the beer into a tertiary. I lost about half a gallon of liquid as it was completely full of cherry pieces. It has been in the tertiary now for week. The SG has remained constant at 1.010 except for today when it read at 1.009.
Like the secondary, there is a layer of sediment roughly an inch thick. It looks like both yeast and some smaller cherry chunks/fibers.
Is it safe to bottle at this point? I want to avoid bottle bombs and do not mind waiting a little longer. If the sediment is mostly dormant yeast and cherry fibers, then a small amount of fermentation should still be going on, but at a very slow rate since all of the easily digested sugars are long gone and the yeast are still eating the chunks. Am I correct in thinking this?
Thanks for your help
