Boris Drenški, an electrician from Zagreb, began winemaking and winegrowing less than 20 years ago. His mentor was a respected Slovenian oenologist and winegrower who directed him towards sweet wines, adapted to the Zagorje terroir that gives grapes of exceptional acidity, while in late and ice harvests sugar levels are high enough to produce serious wines. That is how Mr. Drenški began producing ice wines, and after just a few first harvests he won a handful of Decanter medals. The best Bodren wines like Riesling and Chardonnay ice wines, belong in the highest international predicate class. They are, of course, very expensive.
