I've had it once and thought it was pretty good. I unfortunately don't remember many details. Hopefully you get a clone recipe from someone here.
In case you don't, here's a recipe from an RIS that I made in spring of 2012 that has all of those ingredients. I have a hard time believing they don't have any roasted barley or black patent in there (how is it an RIS without?). If they get all of that from chocolate, you'd need quite a bit, at least 1.5 lbs. Sub the RB with the additional chocolate. I'm not a fan of black patent, even in RIS beers.
- 8 lbs Pale Ale (Marris Otter would be a great Sub)
- 6 lbs 2 row pale
- 1 lb Munich 10L
- 1 lb Roasted Barley
- 0.5 lb Chocolate
- 0.5 lb Special B (dark carmel)
- 0.5 lb C80 (carmel)
Target OG 1.095, target FG 1.025, 9.2% ABV with a the last 3 tenths coming from bottle carbonation.
Hop it how you may, but most RIS beers have little hop flavor/aroma. I looked up their website and saw 75 IBU, and I wouldn't go any lower than that for bitterness to balance the higher finish.
