The private trade company JIDVEI SRL is located in the Tarnave Vineyard, more precisely in the Tarnava Valley, between  Tarnaveni and Blaj, at the common border of Mures and Alba counties.

The vine covers over 1000 ha. Approximately 50 ha are renewed every year. The first state vineyard was founded here in 1949 and it has been gradually extended to a total area of 1000 ha.

The privatisation of the viticultural, fruit-growing sectors and the wine cellar has given a new dimension of Jidvei vineyard development. The Jidvei vinery is financial healthy, as the exports grow monthly and the consumption is high.

The vine plantations were established on the sunny hills on the left hand side of Tarnava Mica, sheltered from the winds, the late spring and the early autumn hoarfrosts.

Vines are planted on hills with east-west exposure at an altitude of 400-450 m.

The lands were recently consolidated and terraced. The brown forest soil enjoys a favourable climate with warm and long autumns, mild summers and winters.

The average temperature is 9.9^oC. In this "Sanctuary of Wine" many varieties of vine are cultivated, recognized and praised in Romania and around the world: Feteasca Regala (320 ha), Riesling (200 ha), Feteasca Alba (100 ha), Traminer (40 ha), Chardonnay (20 ha).

There are also other varieties on 80 ha: Pinot Gris, Oporto and Sylvaner.
