Derek Riggs' iconic artwork for Iron Maiden's ‘The Trooper’ single, featuring band mascot, Eddie, is featured on the bottle label, which will certainly help to garner attention and sales. Publicity stunt? Maybe. Probably. Definitely.
Regardless, like most of Dickinson's musical output, the beer has been painstakingly crafted to be accessible to all, but aimed at a smaller subset of the population. It's more likely to be enjoyed by craft beer enthusiasts than the general public, but could even be enjoyed by those who are content with a case of Bud from the gas station.
Don't let the "ESB" fool you; this ale is neither strong nor bitter. It pours as a translucent caramel color, without excessive head (sorry, Edward T.). I'd heard some complaints about the carbonation level, but I found Trooper to be just right, lending to a lovely, crisp mouth feel, letting the subtle, biscuity flavors of the hops and wheat come through. The smell (the nose, for snobs) matches the flavor; smooth, wheaty, and pleasant.
My only critique is the gentleness. I expect something associated with Maiden's "Air Raid Siren" to come across with more power. Just a touch more flavor, and this could be a beer that I love. Even so, I was very pleasantly surprised by Trooper. I'd expected something with a taste like acrid smoke and horse's breath, but was pleased to discover an enjoyable, easy, highly drinkable beverage. Highly recommended. Well done, Bruce!
