Terroir

• The Aiud winegrowing district is situated to the north of the Alba winegrowing district, with scattered plantings across a hilly-rolling landscape on both sides of the middle Mureș corridor and the lower Arieș corridor, the entire zone falling within viticultural zone B.
• The soils of the winegrowing district belong to the argilluvisol and chernozem-type mollisol classes, with argilluvisols predominating in the forested hill belt through argillo-illuvial brown soils, luvic brown soils, and eu-mezobazic brown soils.
• Among the intrazonal soils, an appreciable proportion of 15–20% consists of regosols and erosional soils on slopes affected by active denudation processes, whose viticultural exploitation requires anti-erosion and agrochemical measures, particularly terracing and fertilisation.
• Mean annual precipitation ranges from 600–700 mm in the Mureș corridor, reaching 615 mm at Aiud, with a maximum during May–August and a prolonged autumn–winter minimum.
• During the harvest period, low temperatures of 5–10°C reduce oxidation-reduction and enzymatic processes, allowing the grapes to maintain their healthy condition and their variety-specific aromas.
• During the grape-ripening period, daytime temperatures fluctuate around a mean of 23°C while night-time temperatures fluctuate around a mean of 12°C, the interplay of these two factors driving a continuous increase in grape sugar content.

• Viticulture in the Aiud winegrowing district is attested from the earliest times, representing a constant preoccupation of growers throughout the centuries with regard to vineyard work, grape varieties, and winemaking technology.
