The winery is located in the municipality of Illmitz in the Burgenland wine-growing region of
Neusiedlersee (Austria). Attached is a guest house. There are also supporting programmes for the festivals in Mörbisch and Margarethen or a day with a carriage ride in the National Park Neusiedlersee. The trained mechanical engineer Willi Opitz began his career as a winegrower in 1995 and is considered one of the best advertisers for Austrian wine abroad. Innovative and unusual marketing activities are set again and again. On November 4, 1996 (US election day) a sweet wine was harvested and named "Mr. President" in honor of Bill Clinton's re-election. A case of it was sent to the White House, Clinton returned the favor with letters of thanks and visited the winery personally in 2001. The "McLaren" was vinified for the Formula I racing team on the occasion of a visit to the winery by Ron Dennis, the head of the McLaren Mercedes racing team, and the "British Airways 1st Class" for the English airline. And in the famous London department stores "Harrod's" and "Fortnum & Mason" the CD "Sound of Wine" is available in the wine department (besides Opitz wines), on which the bubbling of the fermenting Opitz wines can be heard.
The vineyards cover 17 hectares of vines. The main white wine varieties are Pinot Gris, Pinot Blanc and Welschriesling, and for dessert wines Muscat Ottonel, Gewürztraminer and Scheurebe. The most important red wine variety is Pinot Noir, from which the entire spectrum is produced, from dry red wines, rosé and sparkling wines to Trockenbeerenauslese and vinegar. The other red wine varieties are Zweigelt, St. Laurent and
Blaufränkisch. A speciality of the house are the white and red reed wines "Schilfmandl", named after a self-developed procedure. The flagship of the house is the Zweigelt straw wine "Opitz One", named after the famous
Opus One in California; a special bottling of which is "Mr. President". Around 75,000 bottles of wine are produced annually, of which white wines, red wines and dessert wines each account for a third. The "Rohrwolf Tresterbrand" is also produced from Pinot Noir ice wine. The products are exported to many European countries, as well as China, Japan, Malaysia, USA, Canada and South America. In 2005, on the occasion of the 10th anniversary of the company, it was the first winery to be awarded the Export Prize of the Austrian Economy.
