In Radical Brewing Randy Mosher warns that harsh chemicals produced when roasting grains at home can lead to unpleasantly rough tasting beer and that you should leave 2 weeks between roasting and brewing to let these chemicals disipate.
I am planning on brewing an oatmeal stout on saturday and roasted some rolled oats last night but am now unsure whether to use them or not.

Has anyone experienced any problems with roasting oats or is the problem he describes more likely with other grains?
Cheers.
