Russian Imperial Stout

[dad_of_jon]

mj do a yeast to 14% - I got 12.86% from a single packet of rehydrated yeast for 21l.

SO5? I'll have a hunt around and see if I can find it somewhere.

You may have misunderstood me. DoJ suggested 12% based on a 23l batch, if its the same quantity of ingredients but a 19l batch the final alcohol percentage will be much higher.

Do you know which one it is please?

As per the calculator, all my ingredients only predicted 11% for 19L.

Do you have the output of the calculator? I quickly plugged a few values into brewers friend and got something ridiculously off the scale

The 5kg stout malt is a grain in brewersfriend. Didn't your recipe have 5kg of extract?

Thanks a lot!

And that sounds amazing! How does it taste?

 

[user 23602]

I went with 10g of M41... Hope that works!

 

[user 23602]

Excited! A wonderful 10kg box has arrived with all the ingredients! Will get this started on Saturday afternoon whilst I'm recovering from Friday night.

And your certain you know what your starting gravity will be?

Not 100% confident.

I think it's important to highlight this post. 5kg of grain is quite different to 5kg of extract.

You appear to have worked out your numbers with grain rather than extract. I'm not sure any beer yeast will handle the gravity you'll be exposing it to.

No. It was calculated using extract. Or were you referring to @prog99? Because mine is here. Its a guideline, but it's pretty close to what I'm using.

 

[prog99]

It’s still saying 5kg of malt not extract.

Try it now. I think that's right maybe? Sorry, still learning! It's now:

OG: 1.152
FG: 1.031
ABV: 15.95%
IBU: 26.92
SRM: 40.57

@BeerCat I made a mistake and ordered Chocolate Malt instead of Roasted Barely, f**k knows why. Can this still be steeped in 1l of cold water overnight, rinse with 0.5l of cold water the next day and boil for 5 mins to sterilize just like the barely method?

 

[Brew_DD2]

It can be steeped. You are going to struggle to get anywhere bear that final gravity with beer yeast. Also the bitterness is extremely low for such a big beer.
