MNBeer post lists the beer as Flat Earth's five year anniversary brew. The post was almost a month ago, so the growler I bought might've been in the fridge for a while--and then a week in mine before I had time to get a pint poured.
Hazy amber to brown ale--not what I expected for a double IPA. Clean, barely-off-white head that has a nice lace. Heavy grassy hops, citrus and muddled malt in the taste that's somewhat supported by a citrus and biscuit nose. Leaves the mouth dry and hoppy. Slight oiliness betrays a higher gravity, but the alcohol is only apparent in the feel of the beer, which hits like a hammer.
Good beer, but it doesn't have the clean hop pop that I look for in a double IPA. Good, no great, but perfectly fine as a Sunday afternoon beer. Drinking the rest of the growler over the day, warmth really helps the balance of this beer. Take your time if you get a chance with this one. I'm not disappointed with the growler, but I don't see this one becoming a regular without some fine tuning.
