According to Beersmith, the color is 40 SRM (was 44.4), but still at the high end of spec for an imperial stout. The net effect should be less roast and more chocolate flavor. I’m still on the fence about lowering the level of crystal malts, but I hesitate to change the recipe too significantly. I think we may have also talked about upping the oats. Thoughts?

Brewing 5 gallons. Will barrel as much of that as necessary. Ryan Naseman February 11, 2020 at 12:34 pmLog in to Reply I agree and am good with everything above. I’d also prefer not to make too many changes at once, so i’m in favor of moving forward with the above recipe. John Spicer February 21, 2020 at 6:32 amLog in to Reply I brewed this yesterday (2/20), bumped up the grain bill to make about 7 gallons. To get it to all fit in a 10 gallon rubbermaid cooler I substituted some LME for 2 row. Tastes pretty good pre-ferment, more chocolatey than I recall from previous batches. Ryan Naseman February 9, 2020 at 2:32 pmLog in to Reply Yes, I can bring a bomber of the 2019 version John Spicer February 9, 2020 at 8:14 amLog in to Reply Does anyone have a bottle of the 2019 Barreled RIS that they can bring to the 2/10 BOCK meeting (tomorrow)? Would be good to get the brewers for this year’s version around a table to discuss what changes (if any) we should consider. Clay Bunn February 9, 2020 at 6:22 pmLog in to Reply I like that idea! I want to get the recipe finalized soon so people can brew as early as next weekend. John Spicer February 8, 2020 at 7:44 pmLog in to Reply I think we want the roast from the chocolate and roasted barley. However, maybe we don’t need quite so much. So maybe go to 1 lb chocolate, 8 oz roasted barley, and x oz cold steeped dehusked carafa III or blackprinz added in the last 10 minutes of the boil. And ratio down the caramel malts to maybe 10 oz total. John Spicer February 8, 2020 at 7:59 pmLog in to Reply If we do this, we could also consider switching to pale chocolate malt to get a more true chocolate flavor, and using the cold steep to correct the color. Clay Bunn February 7, 2020 at 7:27 pmLog in to Reply We talked last year about steeping grains and ultimately decided not to do it. Maybe this year is the year to try steeping, or adding at the end of the mash the dark & crystal malts? If we do, we might want to keep the recipe fairly close to previous years so that steeping/late dark grain addition is the main variable between this year’s RIS and those from past years. Just a thought, I’ll do whatever you all want. Ryan Naseman February 5, 2020 at 9:36 pmLog in to Reply Below is what we used last year. I got a sharp malt bitterness from this version (which mellowed a bit over time), so I’m open to a few tweaks … similar to what Spicer is mentioning. Maybe back off on the Dark Crystal / Special B a bit and up the chocolate malt (and maybe the flaked oats) + sugar. We can also maybe work through this with steeping some of the grains vs. full mash.

Also a bit astringent. Maybe consider a recipe with less dark crystal, more chocolate malt, some simple sugar to dry it out (dark brown sugar?) and a more attenuative yeast (like WLP090)? Thoughts?
