Climate & Terroir
Istria has a mild Mediterranean climate moderated by the Adriatic, with cooler inland and higher-altitude sites showing continental influence. Soils vary from limestone and flysch to the distinctive terra rossa (red, iron-rich clay) over limestone that favors Teran. Vineyards sit on gentle coastal slopes and karst plateaus, benefitting from sea breezes that preserve acidity and reduce disease pressure; microclimates and varied aspects create diverse expressions across the peninsula.
