Russian Imperial Stout - Good to throw?

[QcSylvanio]

Sup all !

I brewed my first big beer, a Russian Imperial Stout. I believe I didn't throw in enough yeast. I did make a starter. My FG is now at 1.042 and I'm wondering if I can do anything to help now?

Here is the extract recipe :
6.6 Lbs Golgen Ligth LME
6.6 Lbs Sparkling Amber LME
0.5 Lbs corn sugar
1.25 Lbs Roasted Barley (steep)
1 Lbs Special B Dingerman (steep)
0.62 Lbs Pale Chocolate (steep)
0.56 Lbs Munich (steep)
0.07 Lbs Black Patent (steep)
1.5 Oz Millenium 60 min
2 Oz Kent Golding 10 min
1.65 Oz Kent Golding 1 min
Yeast Nutriment
California Ale WLP001.

OG : 1.098
Real OG : 1.096
FG : 1.019
Real FG : 1.042
Batch size : 5.25

I did a 1.6L starter that I decanted and stepped up at 1.6L again.
I went from 1.096 to 1.057.

I then prepared another starter of US-05 from frozen yeast. First step at 700ml and then 1.6L. The gravity went from 1.057 to 1.048.

I then rehydrated two packs of S-04 and throwed in the beer. The gravity went from 1.048 to 1.042.

Is there anything I can do now to help make this beer ok?
HELP !!

I wouldn't worry about it. I had a RIS finish at 1.048 once. People dug how thick and sweet it ended up. Brewed the same beer and it finished at 1.035 and people say "it's much thinner than the last time". Taste it, If you like it drink it.

I agree not to worry about it too much. It sounds like you've already made some efforts to bring down the gravity and your recipe has a lot of "less fermentables" in it.

I currently have a RIS in the carboy and it's been at 1.044 for over a month now. OG was 1.125 and I used WLP007 and have not re-pitched. I'm a little worried, but my recipe called for FG in the 1.040-1.045 range so I feel slightly comforted. Just watch the bottles closely for a few months after bottling to make sure they don't overcarb.

I would recommend thinking more in terms of cell counts than starter volumes - use a calculator like this one here.

Do you use a stir plate for your starters? If so, assuming you used a vial of yeast a couple of months past manufacture date, you should have been fine on the cell counts. If you don't use a stir plate, you might have been as low as half of the cells recommended.

Hey, just a follow-up.

I did bottled it. We will see how it turns in couple month I guess

Thanks for the reply guys!
