I bought a 12 pack variety blend for $12.99 as well. Nothing really screamed amazing.
White IPA: they use lemon and coriander in it with "dwarf" hops and the flavor is interesting to say the least. I did enjoy this one on the beach though. Definitely a summer, warm weather beer.
Session IPA: boring, thin body. Very high on the "pine" tasting variety of hop (simcoe or chinook?)
Black IPA: I did enjoy this one. The amount of roast present lets you know that it isn't a regular IPA. Great hop presence and body. I make a black IPA that is similar, but I like the challenge of making it taste like a regular IPA, but black.
Torpedo (Imperial IPA): I've had this one several times and really enjoy it. A very reasonable, and widely available imperial IPA.
Worth the $12.99 price tag just because it was different.
