In terms of general geography, the term "Dolenjska" applies to most of the Posavje winegrowing region; in ampelographic terms, the Dolenjska winegrowing area encompasses the sites along the right (southern) bank of the Sava River from Litija to the northern slopes of the Gorjanci range. This area is the geological contact between the Alps, the Dinaric Mountains, and the Pannonian plain. Originally, this was a deep valley, later filled in by the Sava and Krka rivers. The sources of thermal water at Catez and Smarjeske toplice are modern reminders of a lively geological past. The margins of this area are still characterized by karst springs ("obrh").
The southern banks of the Sava and the foothills around the Krka River valley are products of the erosion of the surrounding mountains that created gently sloping low hills composed of post-Carbonate loess and sandstone.
The climate is mixed, with alpine and Pannonian influences. Only the southern and southwestern slopes of the low hills descending to the banks of Krka and the flatlands along the Sava are suitable for viticulture.
The vineyards here are mostly vertical. Grass is allowed to grow between the rows to prevent erosion as this area is frequently beset by heavy rainstorms that wash away exposed soil.
The staple wine of this area is the humble Cvicek, traditionally a blend of fourteen different wines (this is now considered to be an exaggeration) - fresh, tart, and low in alcohol. The "recipe" differs from site to site. Most Cvicek is produced for home consumption and never reaches the market: cultivating at least a small mixed vineyard is a traditional hobby of area residents.
The most widely appreciated white blend is Dolenjsko belo; its composition varies, although Laski Rizling, Kraljevina, Rumeni Plavec, Sauvignon, and Beli Pinot are the most common ingredients. This is a light wine, rich in acids, and is believed to have medicinal properties. It is supposed to alleviate chronic rheumatism and arrest the formation of kidney stones.
The cellar in Leskovec also produces a Modra Frankinja with a subtle bouquet and noble aroma. The late harvest Laski Rizling and Sauvignon are the best white wines of the area.
The cellars of Turn Castle house the largest wine archive of the area. Here Cvicek is matured in oak casks. Aged late harvest Laski Rizling and Sauvignon are the pride of the cellar, and among its red wines, the special cure of Modra Frankinja has an unforgettable bouquet.
