Russian Imperial Stout

Well obviously the yeast will lap up all that sugar to begin with but they'll hit a wall hard.
I was flicking through the brewdog recipe archive and if your SG is to be believed theres nothing even close to that SG. I think the highest I saw was around 1.156 and FG of 1.030 using wyeast 1272.

Well, I can only go by what my hydrometer was telling me. Should I hit a wall... Is it worth getting some more yeast? Do it in stages?

But attenuation up to 100%, so it might even dry out...

You'd need a very specific yeast that doesn't die as soon as it hits such a high alcohol content.

And is it okay to add yeast midway through the fermentation?

It's the only way you are going to get even close to a complete fermentation.

The lid on the FV is still swelling every few hours. Can I presume the yeast is still slowly doing its job?

Proper falling down water

Sorry, I don't get what you mean.

I'm guessing it has an alcohol level that makes you fall down after drinking.

 

[user 23602]

That makes sense now lol.

Any updates on how this is going?

He fell over from the gravity sample

 

[user 23602]

I'm still alive and so is the brew (just about). The gravity has gone down... Very slowly, but it's getting there.

As of Saturday morning 1.090.

As of Saturday morning 1.050.

That's nearly 23%!! What did the sample taste like?

 

[user 23602]

I haven't tried it. I'm just leaving it, it's got another week or maybe 2, I haven't decided. I seriously doubt it's 23% as I'm not confident my OG reading was correct, even if that's what it said on the Hydrometer. I mean, a 23+% Impy surely can't be right.

That's impressive patience, I can never resist having a swig of the hydrometer sample

If you're not sure on the OG you'll have to resort to the "drink 3 pints and see what happens" approach to ABV estimation
