Winemaking farm Črnko produces high quality wines from their own vineyards that lie on Jareninski vrh and Slatenik.
Their production is based on old family experience, which they supplement with contemporary methods of quality white wine production. They sell their wines under their own brand since 1983. They sell their wines mostly in Slovenia, but partly also throughout Europe and the USA. The quality of their wines was confirmed numerous times with medals they received in San Francisco, Paris, New York and Montreal.
