Štekar produces wines from Goriška Brda, the hillside wine region of Slovenia's Primorje zone, where Mediterranean and Alpine influences converge. The winery's Malvazija, made from the indigenous Malvazija Istarska variety, represents the region's white wine tradition—a grape that thrives in the area's limestone soils and yields wines of mineral precision. Alongside this regional anchor, Štekar works with Cabernet Franc and Cabernet Sauvignon, varieties that find expression in the Brda's continental climate and elevation. The winery's portfolio has drawn assessment from Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff.
