Repitch to bottle carbonate RIS?

I’ve got a Russian Imperial Stout (OG 1.094, est. FG 1.027) that I’m looking to bottle this weekend. When I brewed, I pitched three packets of Safale US-05 Dry Yeast. It was in the primary three weeks and has been in the secondary for four weeks.

If I’m looking to bottle carbonate using 3/4 cup of priming sugar, is the yeast good to go as is or should I pitch something like 1/2 packet of US-05 to help things along?

I would add fresh yeast to ensure carbonation.

Would a full packet of US-05 work or should I only pitch half to avoid bottle bombs?

Bottle bombs are dependent on the amount of sugar added (or remain), not the amount of yeast.

You could pitch half a pack, but you don’t need to.

I agree, you should be good to go. It takes a really long time to get to the point of needing more yeast at bottling.

I let mine sit in the secondary for 4 months before bottling and it did fine… 10 points weaker or so though. Standard NB imperial stout w/ 1728 I think.
