Gravner
The father of modern "orange wine".
Founded 1901 (Joško from 1970s)Signature · Ribolla Gialla
Joško Gravner turned away from clean, modern white wine to revive ancient methods — long skin contact and ageing in buried Georgian clay amphorae (qvevri).
The result is amber, tannic, profound white wine that helped launch the global "orange wine" movement.
