Coronica vineyards and vines are growing in the red Istrian soil, and, as far as nature allows, the highest possible quality grapes of Istrian indigenous varieties – predominantly Istrian Malvasia and Teran. Depending on the production method and ageing, at Coronica winery two Istrian Malvasia are produced, a fresh-style and an aged Malvasia Istriana, each of which reflects best the features of this white variety. Their pride among the red wines is Gran Teran, a wine of an authentic Istrian character produced from an indigenous Istrian red variety.
