The wine-growing district of Slovenian Istria lies in the rolling hills along the coast and extends from Debeli Rtič to Sečovlje. Due to extraordinary natural conditions, the meticulous Istria wine growers have been cultivating oenology and viticulture traditions for over a millennium. Vinakoper, has kept these traditions alive by operating ten sunny wine-bearing locations, which extend across 590 hectares of Istrian soil.
The wine-growing region of Slovenian Istria is divided into two sub-districts:
- The Coastal District includes the Milje Hills, Tinjan, the broader part of the Rižana Valley, and widely-open areas directly facing the sea, where the climate is characteristically Mediterranean. This region has an annual mean temperature of approximately 13.8°C; an average vegetative phase (April - September) temperature of 19.4°C, and a January mean daily minimum temperature of 1.6°C. Frost is rare. The vines are first exposed to it on approx. 15 November, and last on approx 31 March. Annually, the Coastal District receives about 1,000mm of rainfall.
- The Inland District includes the highest areas of Tinjan and flysch ridges lying in the divide between Mirna, Dragonja, and Rokava. Due to the more continental location and higher elevations, the climate here possesses sub-Mediterranean characteristics.
