Jidvei wines are nurtured in the Tarnave Vineyard, along the two Tarnava rivers: Tarnava Mica and Tarnava Mare. The Tarnave Vineyard is situated near Alba Iulia, the home of the Great Union in 1918, and 150 kilometers away from the ancient Dacien fortress Sarmisegetuza.
Vine cultivation has millenary attestations and the twinning of different nations (Romanians, Hungarians, Sachsen) has led both vine cultivation and wine production to develop techniques and skills with amazing results. Considered to be the second motherland of the Traminer, Tarnave Vineyard owes this fact to the massive colonization in the second half of the thirteenth century with Sachsen from the Mossel – Rhine Valley, who founded Seiden (the old Jidvei denomination).
The first agricultural unit with wine-growing profile of great proportions was founded in 1949 and has developed continually, presently disposing of a cultivated area of approximately 2000 hectares.
The 1999 privatization of the wine-growing and fruit-growing sector and of the cellars, has offered the Tarnave Vineyard new opportunities of development and affirmation of its capacities which led to increase exports and domestic sales.
The vineyard is spread on a surface of about 2000 hectares (with around 250 hectares renewed every year) and it is situated at an altitude between 200-500 meters, with most of the vineyards set on southern exposure slopes, which makes the sun rays and atmospheric circulation to favor vine cultures.
The land benefits of a continental-plateau type climate with an average temperature of +9OC (January -4OC, July +18OC). The moderate temperature during the grapes' maturing period determine slow oxidation reactions, helping to a continual accumulation of sugars and aromas and to a not so accentuated reduction of acidity. The soils are divided into three categories: forest brown, forest brown with different degrees of podzolisation and river-bank soils, all three types of soil enabling vine cultivation.
Vine-growing and Wine-making Technologies
The production of grapes per hectare is between 3000 kilograms and 9000 kilograms per hectare with an average of around 6500 kilograms per hectare.
The constant concern for increasing not only the quantity, but also the quality of the Jidvei wines was translated through an extensive investment program that began with rehabilitating the vine-growing areas - a project worth 11 million Euro - and went on with investments in modern agricultural machinery and environmental-friendly vine-growing technologies. 
The vinification technologies have also been updated and, currently, the cellars are equipped with the latest wine-making machineries controlling every aspect of the process from fermentation to bottling.
These modern technologies together with the classical methods of aging in barrels or bottles – still preserved for some products like vinars or sparkling wine – do nothing more than to supplement the micro climate of the region and the high qualification of the oenology experts giving Jidvei wines remarkable organoleptic properties proven by numerous national and international awards.
