Firestone Walker continues to impress me. Double Jack is a great Imperial IPA. It pours a deep orange color with a big head, and the aroma is pungent, grassy/floral hops and some citrus. The hops are big in the flavor, too. This is a true double. But the malt is big, too. Buttery and smooth, and slightly sweet. I think of this as a slightly twangier Bell's Two Hearted, which is a compliment.
