Beluga from De Kromme Haring from Utrecht.
It is already known that these guys from Utrecht can brew great beers.
Each of their beers refers to fish or animals from the ocean, here also the reference to a sturgeon.
Beluga is a Russian Imperial Stout with the typical flavors of roasted malts, dark chocolate with a slightly creamy character and a rather moderate bitterness.
With an alcohol content of 10.5% still a biter.
As Jeremy Wade of River Monsters would shout: Fish On!
