Hmm. I have some small bottles of Snälleröds snapsar and one of them is Besk. I haven't tasted it yet but do you know if it's similar to bäska droppar? And is bäska droppar similar to that Malört bottle in the picture?
I believe they're all different names for the same liquor, yes. "Malört" means wormword in Swedish, which is what they used to flavor bäsk. Besk is an alternative spelling for bäsk.
I was browsing my comment history and stumbled upon this so I decided to finally open the bottle of Besk. Very strange taste. I wasn't expecting anything like this. Doesn't taste similar to other supposedly wormwood infused liquors like absinthe or vermouth. I've never tasted anything like this. Sort of minty note in bitter flavor I can't describe. This is certainly not my favorite bitter but if I was ever offered one I would happily drink it.
