Weingut Toni Hartl cultivates around 25 hectares of vineyards in two wine-growing regions: the Thermenregion and the Leithaberg. These vineyards produce 50 per cent red wine, 38 per cent white wine (including 10 per cent sparkling wine), 10 per cent rosé and two per cent sweet wine.
The knowledge of the different climatic conditions on either side of the Leithagebirge and the diversity of the vineyard soils in Reisenberg and Purbach allow each variety to be given the optimal site to thrive. One of the main goals of vinification is to bring out the characteristics of each region and its unique identity. New to the range are the natural wines: Amphore Ena, Dyo, Furmint, and Petnat (bottle-fermented sparkling wine). Another sparkling wine from the Brut Classic range is aged on the lees for about two years after the traditional method of fermentation, then riddled and disgorged by hand. In addition to the single vineyard wines, the Reserve range now includes Pinot Noir from the single vineyard Reysenperg in Reisenberg and Chardonnay from the Thenau vineyard in Purbach, both of which are characterised by a high lime content. The wines are only released after three years of ageing and only in exceptionally good years. The Reserve range also includes Blaufränkisch Eisner, which, as its name suggests, comes from vines on one of the top iron-rich sites on the Leithaberg. In optimal interaction with the respective microclimates, the soils form the basis for producing regionally typical, physiologically fully ripe, distinct, and expressive wines.
According to the motto "Everything is on loan", the latest ecological knowledge is applied. In order to maintain the biological-organic balance, attention is paid to careful soil management and the targeted conservation of beneficial insects. The winery has been certified organic since 2010 and is a founding member of the Leithaberg DAC association. The winery has been Demeter certified since 2021.
