With advancing climate change and the need to meet the challenges of the “Green Deal” in agriculture, too, interest in sustainable production methods is growing. Fungal-resistant grape varieties are a functioning alternative for viticulture.
In Austria, according to multiple applications, around 1.5 percent of the vineyard area is currently planted with fungus-resistant grape varieties. This corresponds to an absolute area of around 700 hectares. In Styria there are around 150 hectares (2.9% of the Styrian vineyards). Muscaris, souvignier gris and flower muscatel are most commonly grown here. But what happens outside of Austria in traditionally “conservative” wine-growing countries? - Here is a brief overview of some of the activities in Europe and overseas.
PIWI varieties at a glance - results in the rainy year 2021
PIWI vines have been around for over a hundred years. Only a few were able to establish and hold onto. While the time of the regent seems to have expired, Léon Millot or Maréchal Foch are still being grown. But in times of ecological agriculture and climate change, more and more winegrowers are interested in new varieties that spring up like mushrooms. Piwi pioneer Edy Geiger provides an overview.

The proportion of fungus-resistant grape varieties in Switzerland is 3%. Interest in them is growing steadily, and not just because of this year's capricious weather. The question arises: which varieties are best and how well are they protected against powdery mildew and downy mildew? PIWI pioneer Edy Geiger from Thal (SG) reveals his assessments below. They are supplemented by the perspective of Roman Baumann, who, together with his family in Turtmann (CVS), is growing a wide range of PIWI.

Which wine goes best?
For the first time, the PIWI Austria association hosted the PIWI food summit in downtown Vienna. Ten
Wineries from Austria presented their wines on September 8, 2021, which are among the best in the
this year's wine competition "New / Innovative Grape Varieties" count. The "Labstelle" restaurant
not only offered a worthy setting, but also excellent service. Numerous
Interested guests could try the excellent wines of the Austrian PIWI scene
and get detailed information about PIWI grape varieties. Embedded in the audience tasting
The winning companies were also honored and the certificates and trophies were handed over
Discussion about PIWI varieties and their tasting in the Czech Variety Office on August 16, 2021
ÚKZÚZ (Central Institute for Supervision and Testing in Agriculture), in particular the Director of the Crop Production Department DI Jiří Urban, organized a conference on PIWI grape varieties in the Czech Republic on August 16, 2021 followed by a tasting, to which he attended over thirty people invited. Winemakers who presented their own PIWI wine tastings also took part in the meeting and tasting. Most of the samples presented came from the cellar of the ÚKZÚZ and from the Vinselekt Michlovský company. The meeting was initiated by a lecture by Doz. Miloš Michlovský, dr. hc, who presented the recent history, present and possible future of the breeding of PIWI varieties, which previously took place in Resistant Velké Bílovice and later in Vinselekt Michlovský.
The specialist lecture was very interesting for the participants and the discussion about the future of interspecific grape varieties in the Czech Republic was very lively. Active participants included Dr. Václav Hlaváček, Vice President of the Chamber of Agriculture of the Czech Republic and Chairman of the South Moravian Chamber of Agriculture, as well as Chairman of the Supervisory Board of the Viticulture Association of the Czech Republic, Member of the Board of PIWI International and Chairman of PIWI CZ DI František Mádl, Vice President of PIWI International Dr. Jiří Sedlo, director of the Valtice Higher Viticulture School DI Tomáš Javůrek, Prof. Dr. Pavel Pavloušek, from the Institute of Viticulture and Oenology of the Mendel University in Brno, Director of Znovín Znojmo, AG DI Pavel Vajčner, emeritus director ÚKZÚZ Dr. Jaroslav Staňa, and many others. A total of about 40 wine tastings were presented.
After a lengthy discussion, the participants came to the following conclusions:
The Czech Republic has a long tradition of breeding varieties, the origins of which can be traced back to the founder of genetics, GJ Mendel.
For the further development of viticulture in the Czech Republic, it is necessary to support new, already approved varieties that are more resistant to fungal diseases, above all by promoting their cultivation, but also by selling the wines made from them. This is in line with the goals that the EU has set for the future. With conventional varieties, the CO2 footprint of the wine will always be higher, regardless of the pesticide residues, and the quality of the organic wine will only be comparable with the new PIWI varieties. Compared to most agricultural crops, the vines are ready for greening thanks to more resistant varieties, but it is necessary to encourage the exchange of some varieties. The proportion of PIWI varieties in the vineyards of the Czech Republic (4.1 %) is one of the highest in Europe.
The support for PIWI varieties should be seen as "jump-start" in the early years of the EU's new Common Agricultural Policy (CAP). Once the benefits of these new varieties are proven and their wines have established themselves in the market, they will no longer be needed because the PIWI varieties will then be competitive.
This support should also be introduced for other crops within the framework of the new CAP (Common Agricultural Policy of the EU), outside the budgets of the existing CMO (EU Common Market Organization), for individual agricultural products. This means that farmers are entitled to support under clear EU-wide rules, outside the CMO but within the CAP as an additional cost for the introduction of the new CAP, in return for the restriction of farmers to organic farming.
The Ministry of Agriculture as well as the European Commission and the European Parliament should be asked to achieve these goals as soon as possible.
Large PIWI dossier - varieties, wines and options in DIE ROTE - fruit and viticulture CH
Ganz in der Tugend der Zeitschrift DIE ROTE – Schweizer Zeitschrift für Obst- und Weinbau, die seit 157 Jahren im Zeichen des Wissenstransfers steht, widmet sich DIE ROTE in der Ausgabe 08/2021 intensiv den PIWI-Sorten, zeigt ihre Möglichkeiten auf, aber verschweigt auch die Probleme nicht. Der PIWI-Anteil liegt im Moment in der Schweiz bei 3 %, aber man braucht kein Prophet sein, um zu orakeln, dass er nicht so tief bleiben wird.

The flood disaster has driven most of the Ahr winegrowers to the brink of ruin ... and beyond.
The only thing they have and what can secure their future is the next vintage (unless the vineyards have also been affected).
But how are they supposed to do that?
Established framework conditions and tried and tested structures for the grape harvest cannot take effect this year.
Together we can do it ...
Eva Gerszke from City-country enjoyment and Marion Rockstroh-Kruft got together when Vinissima with an interest in wine, but also with a view to solidarity and “Sometimes you just have to do something”.
I don't want to spray my vines! Interview with agronomist and organic pioneer Fredi Strasser
Fredi Strasser is considered a pioneer when it comes to PIWI viticulture and from an early age was inspired by the idea of not having to spray his vines. Following this ideal, he devoted himself to research and cultivation of fungus-resistant grape varieties throughout his life, and his experience and knowledge can be found in the book Fungal resistant grape varieties held.
