I just bottled a Belgian IPA. It's tasty, but it has a grassy note that I don't really like. The problem is determining which hop gave it the grassy note. I suspect it was Chinook.
I dry hopped this beer with a combination of Nelson Sauvin, Simcoe, Chinook and Centennial.
The reason I suspect it's Chinook is that I also dry hopped a RIS with Chinook, along with Willamette, and it had that same note. I *know* it wasn't the Nelson Sauvin that gave it that character, as I've dry hopped with that hop a ton. But I can't be certain with Centennial, as I've never dry hopped with it.
From reading around, I see mention of a grassy note from Chinook. So, what do you say? I've never picked this up from using Chinook in the boil, which I've done a gazillion times. But this dry hop grassiness is just not so nice.
(Please don't bother asking me about contact times and such. This was only 6 days at around 62 F, so it's not from that. With the last Belgian IPA, I dry hopped with Nelson Sauvin, then my son went into the hospital. He's okay, but I didn't get around to bottling until it'd sat on those hops for 19 days, and NO grassiness, just total awesomeness. So, please don't bother trying to diagnose some other reason for grassiness. It's from one of the hops, straight up.)
Thanks for any input.
