Ferdinand Winery is a family‑run boutique producer in the Brda wine region of Slovenia’s Primorska area, perched on steep, high‑altitude vineyards around Kojsko, Gonjače and Šmartno where marl soils and dramatic temperature shifts help shape wines of harmony, freshness and mineral character. The estate, led by winemaker Matjaž Četrtič, crafts expressive, terroir‑driven wines with a focus on the indigenous Rebula (Ribolla Gialla)—offered in styles from fresh to oak‑aged (Época), macerated (Brutus) and even sparkling—alongside varietals like Malvasia, Pinot Gris, Merlot and Cabernet Sauvignon, often made organically with minimal intervention to reflect the unique hillside terroir.
