The best and strongest Slivo is at a little roadside cafe/kafana south of leposavic, kosovo. It is on the right side, about 4 miles from town. Stop in and just say, 'slivo me'. His slivo looks like water, very very clear, the clearest I've ever seen. His is The BEST!
I still have one bottle remaining, so I have to pick up at least 3 more bottles next time around.
