Vodka in and of itself is not that unusual, but there are unusual vodkas, and I would absolutely classify home made passionflower vodka as beeing unusual.
At the moment Inonly have one bottle of vodka at home, a bottle of Nemiroff DeLux vodka from Ukraine, I just saw it at Systembolaget and thought it was a cool way to both get Vodka and in a small way support Ukraine.
I also have a bottle of Japanese rice vodka on order, I mainly ordered it as it has a beautiful bottle.
