Groszer Wein Gmbh" was founded in 2012 as the successor to the former producer association "Vinum Ferreum"
(Deutsch-Schützen) in the Austrian DAC area of
Eisenberg (South Burgenland). The winery is managed by Matthias Krön and Markus Bach, who is also responsible as cellar master. The winery is located in the municipality of Burg at the foot of the Eisenberg. The business objective was defined as
"to care for the continuation of the best sites on the Eisenberg, to bring out the very special personality of the Eisenberg and to make it accessible to a discerning public all over the world". The vineyards cover 16 hectares of vineyards on the Eisenberg, where wine was grown by the Romans at least 2,000 years ago.
The areas are located in the
Szápari (slate), Croatian Ried, Saybritz (rocky brown earth = mixture of stone and loam), Hummergraben and Rotoler (loam) vineyards. They are planted with the red wine varieties Blaufränkisch, Pinot Noir, Zweigelt, Cabernet Sauvignon, Merlot and Syrah, and with the white wine varieties Welschriesling, Grüner Veltliner, Muscat and Pinot Blanc. The quality criteria are low
yields from very old vines, some of which are over 65 years old, and selective manual harvesting in 20-kilogram boxes to ensure only ripe and healthy grapes.
The musts are fermented
spontaneously and aged in 500 and 1,600 litre wooden barrels with the aim of achieving a harmonious balance between minerality and acidity. The product range includes the following wines: a single-varietal Blaufränkisch
Eisenberg DAC, a red wine cuvée (Zweigelt, Cabernet Sauvignon, Syrah, Merlot), a white wine cuvée (Welschriesling, Weißburgunder, Grüner Veltliner, Muskateller), a
Gemischter Satz, as well as Blaufränkisch site wines from the Saybritz and Szápari vineyards. As a sign of authenticity, the wines are bottled exclusively in 1-litre bottles, as these were the classic container for wines from southern Burgenland until the 1970s
