The winery is located in the community of Joching in the Lower Austrian wine growing region Wachau. Attached is a restaurant with a view of the vineyards and the neighbouring Danube. The origin goes back to the year 1910, when Anton Jamek bought the first vineyards and barrels. The business was expanded by his son Josef Jamek (1919-2011) and developed to its current size. He was one of the founding fathers of the Vinea Wachau Nobilis Districtus Association in 1983. The acquisition of the Klaus vineyard, predestined for Riesling, in 1959 was a groundbreaking step. From there, he bottled the first Riesling in 1960, single-varietal, single vineyard and natural. This was a very courageous and innovative decision for that time. Josef Jamek is considered a pioneer and doyen of the Austrian wine scene. The winery is often called "JJJ", which stands for Josef, Jamek and Joching. Since 1996 the business has been run by Hans Altmann (son-in-law) and his wife Jutta.
The vineyards comprise 25 hectares of vineyards in the Achleiten, Freiheit, Hochrain, Klaus, Kollmitz, Liebenberg, Marienfeld, Pichl and Stein am Rain areas. They are planted with the white wine varieties Riesling, Grüner Veltliner,Pinot Blanc, Chardonnay and Gelber Muskateller as well as the red wine varieties Zweigelt andPinot Noir. Natural viticulture is practiced. The grape harvest is carried out with 100% selective manual harvest. The vinification is carried out according to the old Wachau tradition, which means complete fermentation of the musts with the grape's own yeasts until natural fermentation stops. The musts ferment in stainless steel tanks and the wines then mature in large wooden barrels.
Among the premium wines are Grüner Veltliner and Riesling in the qualities Steinfeder, Federspiel and Smaragd. The winery is a member of Vinea Wachau Nobilis Districtus. When Josef Jamek retired in 1996, the distillery was taken over by his grandson Markus Wieser and spun off as an independent business "Destillerie Wieser". The "JJJ" on some bottle labels of the brandies reminds of the origin.
