Newly approved PIWI varieties in the wine regions of Europe
In the Official Journal of the EU C 222 of June 26, 2023, a new (PIWI) variety was approved for the PDO "Champagne". The Voltis variety has been added to the existing seven main varieties. The maximum permitted grape yield is 15.5 t/ha.
A notice on the creation of the new German PGI "Großräschener See" was published in the Official Journal of the EU C 222 on 26/06/2023. The cultivated varieties are the PIWI varieties Solaris, Cabernet blanc, Johanniter and Pinotin. The PGI is located in Brandenburg on the Großräschener See, near the border with Saxony. The maximum yield is set at 90 hl/ha.
In the Official Journal of the EU C 230 of June 30, 2023, the approval of new varieties (PIWI) for the PGI "Pays d'Hérault" (near Montpellier) was granted. A total of 17 new PIWI varieties were added and 18 old varieties that are no longer used were removed. The newly approved PIWI varieties are Artaban N, Bronner B, Cabernet blanc B, Cabernet Cortis N, Floreal B, Johanniter B, Monarch N, Muscaris B, Pinotin N, Prior N, Saphira B, Sauvignac B, Solaris B, Soreli B, Souvigner gris B, Vidoc N and Voltis B. (N=Noir, B= Blanc)
The white grape variety cultivated at the Julius Kühn Institute with pleasant exotic fruit aromas is resistant to several pathogens.
(Siebeldingen) Vine breeding takes time. This also and especially applies to the new grape variety Calardis Musqué. It was crossed in 1964 at the Geilweilerhof in Siebeldingen from Bacchus and Seyval Blanc. 59 years later, the development of vine breeding at the Julius Kühn Institute (JKI), the Federal Research Institute for Cultivated Plants, has now been awarded plant variety protection.
Calardis Musqué is one of the so-called PIWI (fungus-resistant grape varieties). In addition to moderate resistance to powdery mildew, downy mildew and botrytis, it also has a high resistance to black rot. These properties mean that significantly fewer pesticides have to be applied during cultivation - an important step towards more sustainable viticulture and also essential for organic cultivation.

Lively acidity and exotic fruit notes
The wines from Calardis Musqué are sensory. The grape variety stands for a delicate muscat note reminiscent of Traminer in combination with exotic aromas such as mango, passion fruit, grapefruit and gooseberry. The lively acidity makes the wine very appealing and gives it the necessary depth. During the long test period and independent of the environmental conditions, the high quality of the wines has proven to be extraordinarily consistent. In the annual blind tastings at the Geilweilerhof in Siebeldingen, which are organized by the JKI Institute for Vine Breeding, it became the favorite of the guests.
Calardis Musqué is somewhat more demanding to cultivate than other new breeds due to its stingy grape formation and tendency to trickle down. However, the increased effort in the vineyard and the possibly reduced yield depending on the weather are rewarded by the consistently high quality of the wines.
The variety has been classified for cultivation in the Federal Republic of Germany since 2021. Interested wineries can obtain the grape variety from selected vine growers. Your name refers to a historical name for the Geilweilerhof, Calardiswilre.
The Julius Kühn Institute (JKI) unites 18 specialist institutes at nine locations in Germany under one roof. Headquarters is Quedlinburg. Other locations are Braunschweig, Berlin, Kleinmachnow, Dresden, Dossenheim, Münster, Siebeldingen and Groß Lüsewitz. The Federal Research Institute for Cultivated Plants is one of four research institutes of the Federal Ministry of Food and Agriculture (BMEL).
Since 2021, when many winegrowers were only able to keep fungal diseases under control with great difficulty, interest in PIWI vines has risen sharply. Especially because of the prospect of financial aid for new plants. PIWI pioneer Edy Geiger presents what he sees as the most promising varieties.
Pilzwiderstandsfähige Rebsorten (Piwis) erfahren derzeit ein gesteigertes Interesse: Forschungen werden intensiviert, Vereinigungen zu diesem Thema gegründet und Pfropfreben mancher Sorten sind in Deutschland auf 3 Jahre hin ausverkauft. Gleichzeitig will die Zusammensetzung des Rebsortenportfolios innerhalb eines Betriebs gut über legt sein. Arno Becker vom DLR Rheinhessen-Nahe-Hunsrück möchte mit der Erstellung einer „Piwi-Pedia“ Hilfestellung geben.
Ziel dieses Beitrags ist es, vorhandenes Wissen zusammenzuführen, fortzuschreiben und einen möglichst umfassenden Überblick zu vermitteln. Schließlich werden immer wieder Erkenntnisse über Versuchsserien veröffentlicht, die zwar Teile des Themas darstellen, aber es naturgemäß nicht in der Gesamtheit abbilden können.
Zudem hat der Komplex pilzwiderstandsfähige Rebsorten eine hohe Dynamik, so dass es der Fachliteratur oft schwerfällt, Schritt zu halten.
Bei Züchterangaben werden zudem überwiegend die positiven Attribute in den Vordergrund gestellt.

Trains named after PIWI varieties in the Czech Republic
The Czech Republic is divided into 14 regions, one of which is the South Moravian Region. About 94 % of the country's 18 thousand hectares of vineyards are in this region. The region has decided to gradually buy 37 new trains from the Škoda Group starting in 2022 and to name them after the grape varieties grown here. A total of 61 grape varieties are permitted for quality wine in the Czech Republic, including 13 PIWI varieties. Of the new trains, 4 will carry PIWI variety names: Hibernal, Erilon, Malverina and Savilon. The photos show the first PIWI trains that are already on their way through the region.
PIWI ITALIA IS ESTABLISHED TO PROMOTE GRAPE VARIETIES RESISTANT TO FUNGAL DISEASES
Press Release April 2023 – Source: Wineroots.it
The new Italian section of the association, which already has 16 sections worldwide, was founded at Vinitaly
On the occasion of Vinitaly, the Italian PIWI regional associations founded PIWI ITALIA, a working group for the promotion of products made from fungus-resistant grape varieties.
This working group, made up of producers of wines and grape varieties defined as resistant to fungal diseases in vines, as well as some representatives of Italian research dealing with the selection of these grape varieties, laid the foundations for the new organization PIWI Italia, the will be part of the international network of PIWI International.

The use of new disease-resistant grapevine varieties is a long-term but promising solution to reduce chemical inputs in viticulture. However, little is known about water deficit effects on these varieties, notably regarding berry composition. This study is aimed at characterizing the primary metabolites and thiol precursors levels of 6 fungi-resistant varieties and Syrah. Vines were grown under field conditions and under different water supply levels, and harvested at the phloem unloading arrest. A great variability among varieties regarding the levels of thiol precursors was observed, with the highest concentration, of 539 μg/kg, being observed in the 3176-N, a hybrid displaying red fruits. Water deficit negatively and equally impacted the accumulation of sugars, organic acids, and thiol precursors per berry and per plant, with minor effects on their concentration. The observed losses of metabolites per cultivation area suggest that water deficits can lead to significant economic losses for the produce.
Soon, Sweden will be able to print exactly where the wine comes from. The work to obtain PGI status is in full swing.
– The idea is to divide the origin according to existing landscapes, says Emma Serner, chairman of the winegrowers‘ trade association.
Since Sweden became an EU official wine country in 1999, development has gone at record speed. Today, there are nearly 200 hectares of vineyards and two years ago SBOV, Sweden’s Branch Organization for Oenology & Viticulture, was formed. Work is now underway with a PGI approval to be able to write, for example, Wine from Skåne instead of Wine from Sweden. Skåne is Sweden’s southernmost region where most of the vineyards are located.
Emma Serner, chairman of SBOV and founder of Långmyre Vinery on Gotland in the Baltic Sea, says:
– We hope to assert ourselves more internationally with a geographical designation of origin. PGI is a quality development.
Work is currently underway to define what distinguishes wines from the various landscapes. The intention is to target quality, not a specific flavor profile.
– We will be liberal so as not to paint ourselves into a corner. The focus is on quality, that the wine has no defects.
Regarding regional differences in terms of terroir, Emma Serner says as an example:
– Here on Gotland, we have calcareous soil, dry weather and a late spring, which leaves a certain mark on the wine. In Skåne, it is windier and more rain, with late, warm autumns.
The hope is to get the PGI system approved in a year or so. Proceeding with PDO may come at a later stage.
– The PDO is much narrower and then we end up on much smaller areas than today’s landscapes. We start with PGI as a way for Swedish wine to market itself.
As far as the assessment is concerned, the ambition is to form a sensory center in collaboration with, among others, the Swedish University of Agriculture.
In Sweden, around 95% of the grapes are PIWI, where Solaris still is the big player. However, more and more attention is directed towards the new generation of PIWI, where especially Kullabergs Vingård is very optimistic about Souvignier Gris, Cabernet Noir and Pinot Nova.
Short supply chains and the cultivation of fungus-resistant grape varieties
Robert Finger, Lucca Zachmann, Chloe McCallum*
The grapevine is economically and culturally central to Swiss agriculture, but it is also the crop with the greatest use of pesticides. By using fungus-resistant grape varieties, the use of pesticides could be significantly reduced while maintaining the same quantity and quality of production. However, these varieties have only rarely been used to date. Using survey data from 775 Swiss vine producers (from now on 'producers'), we examine factors that influence the use of fungus-resistant varieties and analyze in particular the importance of marketing channels and the role of short supply chains. 20.1 % of respondents grow fungus-resistant varieties, but the acreage is only 1.2 %. Our results lead to a simple conclusion: the closer producers are to the end consumer, the more likely it is that fungus-resistant varieties will be used. For example, producers who mainly sell their wine through direct marketing are significantly more likely (8-38 %) to use fungus-resistant varieties.

Abstract: Using fungus-resistant grapevine varieties can reducepesticide use substantially, while maintaining productionquantity and quality. Using survey data from 775 pro-ducers in Switzerland, we investigate the adoption offungus-resistant varieties and especially analyze the rele-vance of marketing channels and short supply chains.We find that 20.1% of respondents use fungus-resistantvarieties but the acreage is only 1.2%. Our results narrowdown to a simple conclusion: the less distant the pro-ducer is from the final consumer, the more likely theyuse fungus-resistant varieties. For example, producersselling their wine mainly via direct marketing have ahigher (8%–38%) uptake of fungus-resistant varieties.
