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.
Short supply chains and the cultivation of fungus-resistant grape varieties

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.
SOUTH TYROL: FIELD LAB FOR FRUIT AND VINE GROWING OPENED
At the end of October, a digital outdoor laboratory for fruit growing and viticulture, also known by the abbreviation LIDO (Laimburg Integrated Digital Orchard), was inaugurated at the Laimburg research center (South Tyrol). The aim of the smart, innovative and sustainable outdoor laboratory is to promote innovation in the field of digitization and robotics in agriculture.
Since the end of October, the LIDO has been available to companies and research institutions to use, test and demonstrate to the public existing and new technologies under practical conditions. The goal: Digitization and robotics can support sustainable, knowledge-based production and the careful use of resources in order to equip agriculture for the challenges of the future. For this reason, the Laimburg Research Center has dedicated itself to the topic of "Digital Innovation and Smart Technologies" in one of its five main research areas until 2030. Numerous projects and activities related to digitization, big data, non-destructive quality determination, automation and modern breeding technologies contribute to the implementation of this focus. Against this background, the test center has set up two outdoor laboratories for fruit and wine growing. "We stand for smart and quality-oriented food production that is more efficient, economical and ecologically sustainable," explains Michael Oberhuber, Director of the Laimburg Research Center.

In the current climatic context, with milder winters leading to earlier budburst in most wine regions, vines are exposed to the risk of spring frosts for a longer period. Depending on the year, frost can lead to yield losses of between 20 and 100 %, jeopardizing the economic survival of wine estates. In addition, by destroying young shoots, spring frosts can impact the following season’s production, by reducing the number of canes available for pruning, for example. Late pruning is one method to combat spring frosts (Ravas, 1912; Frioni et al., 2019).

Divico wines blended with Pinot noir - good quality and intense colour
Divico, Agroscope's new disease-resistant grape variety, is valued for the quality of the wines made from it. Assemblage trials with the Pinot noir variety have shown that Divico is suitable for correcting color intensity.
With an area of almost 3900 ha in 2020, Pinot noir is the most commonly cultivated variety in Switzerland. It is widespread in all wine-growing regions north of the Alps. The good reputation is based on the fine and typical bouquet of its wines, which is characterized by fruity notes and a good structure as well as very delicate and velvety tannins. Visually, the color intensity is sometimes judged to be a bit weak. Dyer grapes such as Dakapo and Dunkelfelder are therefore cultivated in Switzerland, and their wines are used in low-percentage blends to improve the color of Pinot noir. With the first red grape variety developed by Agroscope and approved in 2013, which is resistant to downy mildew and powdery mildew as well as gray mold, another variety is available that is suitable for this purpose.

Macromolecular characterization of disease resistant red wine varieties (PIWI)
AIM: Fungal Resistant (PIWI) are disease resistant Vitis vinifera interspecific hybrid varieties that are receiving increasing attention for ability to ripen in cool climates and their resistance to grapevine fungal diseases. Wines produced from these varieties have not been characterized, especially regarding their macromolecular composition. This study characterized and quantified colloid-forming molecules (proteins, polysaccharides and phenolics) of red PIWI wines produced in the UK. (more…)
Diversity buffers winegrowing regions from climate change losses
Increasing diversity within crops may be a powerful way to reduce agricultural declines from climate change. As such, it has garnered increasing attention, especially in documenting within-crop diversity through different cultivars or wild relatives. Yet, there are few tests of whether this diversity can mitigate losses with warming. Here, using European (predominantly French) databases to forecast winegrape phenology, we test if shifting cultivars changes predictions of future growing regions. We find that cultivar diversity halved potential losses of winegrowing regions under a 2 °C warming scenario and could reduce losses by a third if warming reaches 4 °C. Thus, diversity—if adopted by growers locally—can mitigate agricultural losses, but its effectiveness will depend on global decisions regarding future emissions.
