The cellar technique equipment of the production site in Jois, completed in 2004, ranks among the most modern in Europe. The computerized cellar secures hygienic and safe production measures which meet highest quality standards.

Fermentation of the selected grape material takes place in computer-controlled stainless steel tanks. These fermentation vessels used in the Hillinger winery are jacketed tanks allowing cool fermentation and maturation of the wine due to refrigerating coils between the two walls – a fact which plays an important role in white wine production. Furthermore the stainless steel tanks guarantee a production according to highest hygienic guide lines as well as a controlled fermentation due to exact temperature regulation. Especially fresh fruity wines like Welschriesling, Riesling, Sauvignon blanc and light red wines are vinificated in stainless steel tanks.

The barrique-barrels of the Hillinger Winery are exclusively made of finest French holly oak wood (Allier and Tronçais oak). The sweet, spicy tannin of the wood favourably supports the wine flavours. With regard to white wine, barrique barrels are predominantly used for fermentation while with red wines only maturation takes place in barriques. The classic barrique holds 225 litres and in most cases is only filled twice to guarantee top quality.
