Situated near the village of Orešje some 4km north of Sevnica, the Mastnak winery is an old family business that moved to its current modern premises in 2006. The sprawling 1400m² central building may only be a few years old, but it's built in a traditional farmhouse style, with large open spaces and a gorgeous old-fashioned open fire place in the centre of the main dining hall. While the place was obviously set up with larger groups in mind, the friendly staff will gladly cater to independent travellers, including guided tours of the wine cellar and bottling facilities to go along with the requisite wine tastings. Throughout Slovenia the name Mastnak is synonymous with sparkling wines, and you can taste up to six different varieties - including our favourite, the award-winning Valentina, a modri pinot rosé that is simply delectable.
