Yeah, I recently did a couple SMaSHs to compare Simcoe and Columbus, but it was only about 35 IBU. I've done 4 APA SMaSHs in a row now and I really liked them all. I'm getting ready to do another APA. I'm starting with simple APA recipe in the 45-50 IBU range and I wanted to try to add to the flavor a little bit. I just was wondering what flavorings people out there have tried that worked well with a Simcoe or Columbus for bittering. Whether it's a different hop, spice, fruit, specialty malt or whatever.
