There's a lot of discussion about simplifying grain bills nowadays, even in beers like RIS. In general terms I agree that simple is better, but I just wanted to post a recent experience.
Due to some personal circumstances that I won't get into right now, I haven't been able to brew for a very long time. Around the beginning of June it was really killing me that I hadn't brewed in months. So one day I dug through what I had on hand (which is a crap ton of stuff, mostly hops) and made up a kitchen sink brew (see recipe below). I made up a recipe based on what would use up the most leftovers and it ended up being a stout. After 15 days in the primary I crash chilled it to 35f. The personal circumstances that I mentioned didn't allow me to get back to it until it had set for another 9 weeks. That’s 11 weeks in the primary and a complete kitchen sink recipe - guess what, it's one hell of a stout and is drinking very well. I'm not trying to pick a fight when I say that had I posted the following recipe here I no doubt would have been told to simplify the grain bill. I guess I'm just saying that there's room for all kinds of recipes (and tastes), even a few complex ones. Cheers, j
