It's usually 70 €, but on discount for 50 € in one shop. Pricey experiment. Not sure whether I'll indulge. Apparently there's only 200 something bottles of this stuff.
Edit: I think I might. They also have Old Overholt Straight Rye for 24.70 € on discount (1 L), which is a good price. Also, the "Islay" expression (aged 10 years, then finished 2 years in Port Ellen casks) was highly recommended by a known German bartender/barowner/whatever a while ago.
