Just bought a bottle of barleywine from Alko and tried it. Was well worth trying. Sort of bittersweet in a good way (both quite bitter and quite sweet).
It was called Criminally Bad Elf, and I think this is the only barleywine in Alko.
BTW, Alko webpage lists all the kinds of data on beers nowadays: wort strength, color, bitterness, energy, you name it. Now that's what I call good service!
