Hops? Lagunitas 2009 Correction Ale

I had a Correction Ale last night and it was a really good, unique beer. Maybe one of the best beers I have had with a twist off cap.

Does anyone know what kind of hops they use? This beer to me tasted just like grapefruit, I'm guessing cascade but I am not too experienced with brewing yet.

BTW, I like the drunken rant on the side of the bottle, pretty funny. The beer also proclaims it is "Not a double IPA, just a good American Ale."

O.G. 1.062
I.B.U. 74.2

Take a listen here:
The Brewing Network.com - :

They interview 3 brewers from Lagunitas and talk about that beer. I am pretty sure the type of hop comes up but I do not remeber off the top of my head.

Going to listen to it, but with intense grapefruit, the first hop that comes to mind is simcoe. Amarillo, cascade maybe centennial could all be in there to.

Thanks everyone for the tips.

I tried to listen to the podcast but it was going to take 8+ hours to download, my computer always finds an excuse not to download stuff like that. (lazy bastard)
