You have to use it and see for yourself. I like it, my wife does not. +1
I think it is about personal smell/flavor. And I really do believe the ability to detect cattiness and dankness is genetic to some degree. For me, simcoe is all cat-pee and I will avoid using it. In fact, I know of award-winning commercial beers that generously use Simcoe and I nearly gag when smelling/tasting, while the person next to me is in hop euphoria. I am not arguing with those that love the aroma and flavor. I'm sure that's what they experience. So, long story short, use your own judgement. And there are a lot of commercial beers to help with Simcoe research
I agree with the cattiness comments. It smells like a dirty liter box to me…but it is popular nonetheless. I think if you are careful with it and pair it well with some other hops, specifically amarillo and citra as other have said, it can be drinkable. I think it a personal preference. Try it out and see what you think.
