Viticulture in the climate trap?

November 5, 2021, 6:00 p.m. - 8:00 p.m.

How can research help to make viticulture sustainable in times of climate change? This question is the focus of the online event with experts from breeding research, viticulture and wine production.

Climate change poses major tasks for winemakers and growers. Increasing weather extremes increasingly lead to ideal conditions for pests and pathogens of the vine. For example, the rainy spring and summer of 2021 led to a very high pressure of infestation by the downy mildew pathogen, which can lead to yield losses and reduced quality. In addition, increased late frosts or heat waves can lead to a decline in yield. In addition, grapes ripen earlier in years with higher average temperatures and there is a risk that white wines in particular will lose their sparkling character, for which German wine is valued.

A variety change is therefore pending in German viticulture. More resistant grape varieties are in demand that will continue to produce high-quality wines in the future. Our experts in the studio give a multimedia outlook, present wines from sustainable new grape varieties at a tasting and discuss with the audience: What should and can research do to make German viticulture fit for the future.

This event of the Julius Kühn Institute is a project funded by the Federal Ministry of Education and Research (BMBF) (MaKOWIZ project - Management of Climate Change in Fruit and Viticulture with Innovative Breeding) as part of the Science Year 2020 | 21.

The Science Year is dedicated to the bioeconomy, a sustainable and bio-based economy that is no longer based on fossil raw materials.

The scarcity of resources, the growing world population, species decline and climate change make a change in economic methods inevitable. Bioeconomy research creates innovations that can provide answers to these challenges.

In 32 projects within the framework of the Science Year, bioeconomy research is presented to the public in numerous interactive event formats. Discussion rounds and participatory formats offer citizens the opportunity to find out more about the bioeconomy, to exchange ideas and to actively help shape change.

PIWIS - around the world

Wolfgang Renner, Research Station Haidegg, Chairman PIWI Austria, Board Member PIWI International

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.

How robust are PIWI vines?

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.

Discussion about PIWI varieties and their tasting in the Czech Variety Office on August 16, 2021

Jiri Sedlo

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.

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.

Falstaff - PIWI Trophy 2021 - Results

Mushroom-resistant new breeds, so-called PiWis, often have strange names such as: Pinotin, Souvignier gris or Sauvignac. Stylistically, they are very similar to the European varieties, which have to be sprayed a lot more. The Falstaff tasting shows that exciting things happen!
