Just as a general addition to this thread (not having read it all):
I recently attempted a "Dank" IPA. Of the hops considered "Dank", my LHBS really only had Columbus and Apollo. My recipe was something like:
2.5 Gallons, partial mash:
Malt:
3 lb Pilsener LME
2 lb Pale malt
.25 lb Victory
.25 lb Munich 10L
Yeast: US-05
This ended up being ~6% ABV, though I don't have the measurements on me.
Hops:
60m Bravo, bittering to ~45 IBUs.
Flame Out: Columbus, 1 oz
Flame Out: Apollo, 2 oz
Dry Hop: Columbus, 1 oz - 7 days
Dry Hop: Apollo, 2 oz - 7 days
As you can see, I used over 6 ounces of "Dank" hops for a 2.5 gallon batch, so the equivalent of 12 ounces for 5 gallons.
The result? A totally drinkable beer that reminds me nothing of "Dank". The beer is definitely herbal, but in a spicy/earthy/generically hoppy way, not at all like the smell of marijuana. I can also see some people reading this smell as oniony or garlicky, though I found this to be quite pleasant. From what I can tell, there are absolutely no fruity flavors, though there may be a slight hint of citrus.
The aroma of the beer is also pretty subdued for what I would expect out of 12 ounces of hops. If you had said that this beer had three ounces of hops, or less, I would believe you. I think, in general, Apollo seems to be a fairly mild hop for aroma/flavor.
Anyway, it did turn out to be a pretty damn tasty beer, regardless, just not at all what I was shooting for. The beer itself is something good enough to brew again, but I can't see myself spending all that cash on hops for such a muted aroma and flavor.
