I don't think I'd mash that high  using that much Carafoam, as I think it would finish pretty high. Otherwise looks quite tasty.

[weithman5]

i like it but i think i would spread the hops out a bit or if you just want such high ibu i would use only one or the other., as they are both such high ibu for 60 minutes

I don't think you will get 75% efficiency on a 1.115 beer.  You might have some DME available.

Otherwise it looks yummy.

I usually do a 158degF mash for big chewy beers too.

I don't understand "You might have some DME available."

he was recommending that you have some Dry Malt Extract on hand in case you miss your gravity.

I think you will have plenty of body and mouthfeel in the beer without the Carafoam. I would just sub 2 more lbs of Pale Malt. I like to include some Special B malt (.5 - 1lb) on my RIS to help with the plum / raisin flavors. I also agree with the mash temp suggestion. 154F max.

Thanks for the clarification morticaixavier - I figured that was what poster was referring to.

Snowtiger - do you feel that the Special B comes through the roast barley?

[jmcamerlengo]

to save you a few bucks. Imperial stouts I've found dont really benefit from the flavor advantages of Maris Otter, 2 row works fine. All the roasted malt covers the flavors of MO up a bit.

On the other hand, he very well might.  My last three "big" beers came in at 1.082 @ 75.51% BHE, 1.096 @ 74.55% BHE, and 1.102 @ 75.80% BHE.

Thank you for your input.  I seriously doubt he will get a 75% efficiency on a 1.115 beer.  I am just trying to help prevent a dissapointing outcome based on my experience. 

Have you brewed a 1.115 beer with 75% efficiency (without boiling for 8 hours)?  Has anyone?  If he has done it before I honor him.  If you have, please tell us how you did it.

Cheers

Yes, I think it comes through. Adds to the complexity (with those plum/raisin flavors I mentioned).

I've come aweful close, and I only had to boil for 3 hours. 

Did a partigyle and if I calculated the whole batch efficiency it was right around 75%. The first runnings were a 1.115 and the second runnings 1.034. There were a lot of second runnings. I think I might even have squeezed out a couple quarts of starter wort out of that mash.

[tom]

Of course, only first runnings or boiling the bejeebus out of it will get to 1.115.  (Or a doble-doble mash ala Randy Mosher.)  Although the total efficiency for both of your beers was 75%, the efficiency for the big beer was probably only about 50%.

[craigweiser]

What do you all think I will get for efficiency so I can scale up to accommodate for this big A beer?
