Thanks for the input. Mine had an estimated OG of 1.08 to 1.09. I should have been in that area as I followed everything down to the letter. With that mid range OG for this style I would think it should get at least in the 1.02 range. No?
So, if you put it dead in the center at 1.085, 1.020 would be 76.5% attenuation, which is pretty high IMHO. 1.030 would be 65%.
As further examples, in Brewing Classic Styles, Jamil has 2 recipes. One goes from 1.098 to 1.030, which is 69.4% attenuation, one goes from 1.100 to 1.037, which is only 63% attenuation. And the guy Jamil took that recipe from states that if it went any lower, it'd be too dry for balance.
With RIS, it depends on how much roast, how many IBUs and such to determine if you've got balance. If you use a ton of roast, you'd likely need more sweetness to balance the beer out.
I'll go back to what I said before: Don't obsess on numbers, obsess on taste. If you think the beer tastes good and is balanced, take no further action. If you think it needs to be drier, then consider your options.
But, you learned a lesson here, right? Next time, make a starter.
