Mackmyra has a head start but the rest are catching up.
I have tried Gotland Whiskey and Wannborga so far.
I would say that Gotland Whiskey, Gute and Wannborga need some more years of development.
And in this case I would say that Gotlands Whiskey is on a good run.
I had the pleasure of tasting some very young samples from the new Swedish distillery Agitator whisky and was pleasantly surprised, although I will admit that they were the last of way too many drams I tried at the 2019 Öl & Whiskymässa so my taste buds at that moment were not the most discerning. I don't think they are releasing any of their product yet but I certainly look forward to trying it again!
