No matter where you are in Posavje you're never far from either a wine cellar or a castle, and when you find both together it's a recipe for a wine tasting that you'll never forget. Two of Posavje's more atmospheric wine cellars are at the newly renovated Sevnica Castle, which beautifully showcases dozens of wines from around the region and even a few from other parts of Slovenia, and the family-run Klakočar-Wisell wine cellar situated at Bizeljsko Castle, where guests can sample award-winning local wine and some exotic home-made schnapps in a cellar that looks much like it did 500 years ago.
