This was brewed in 2009 to honour Darwin's 200th birthday and the 150th anniversary of the publication of On the Origin of Species. It is a "mutated double IPA designed with three English hops to pay tribute to his descent".
Dense head. Lovely woody hops, some fruitiness and sweetness from the malts, but this isn't at all like the US IPAs with their aggressive and sweet style. Fairly low carbonation, deliciously bitter and hoppy which nicely counteracts the sweetness, I like it very much despite a bit of alcohol showing on the finish.
