German winemaker Jürgen Amthor has successfully harvested his Cabernet Cortis – 95% healthy after only two sprays a year. We look at this and the potential of other leading disease-resistant grape varieties…
Jürgen Amthor, the owner of the first probiotic PIWI vineyard in Franconia, Germany, is happy about his harvest of the fungal-resistant red grape variety Cabernet Cortis. The grapes are 95% healthy. They have a very ripe and fruity aroma with a sugar content of 85°Oe (20.5 Brix) and balanced acidity.
Hybrids: Finding a Place
In a world apparently tiring of experts, there is at least one in the viticultural sphere that we should be grateful for. In 2020, research led by Andrew Walker, a geneticist and professor of viticulture and enology at UC Davis, led to the release of five new grape varieties. They have some advantages in common. Sarah Philips McCartan reports.

The second edition of the event on the theme of PIWI vines has come to an end
The great challenge of the resistant grape varieties, success for the 2nd PIWI wine competition in San Michele
Friday 02 December 2022
The second edition of the national tasting of PIWl wines organized by the Edmund Mach Foundation to promote “sustainable” grape varieties bred to be resistant (or rather tolerant) to the main vine diseases: powdery mildew and downy mildew , completed successfully.
Today, in the Aula Magna, in the presence of well-known international experts in the field of genetic research and sustainable viticulture, the award ceremony for the award-winning wineries took place. 44 Italian wineries took part in the event, which was supported by the Consortium for Wine Innovation and the association PIWI International. The 82 competition wines, divided into six categories (red, white, orange, sparkling, crémant, classic method), were judged on November 9th and 10th by a panel of 30 qualified experts, assisted by the students of the viticulture course .

PIWI International Meeting from November 11th to 13th, 2022 in Neustadt ad Weinstrasse – Germany
Author: Jiri Sedlo
Members of the "PIWI International" association from Germany, Austria, the Czech Republic, Switzerland, Italy, Poland and the Netherlands met in Neustadt an der Weinstrasse for the annual general meeting. Most of them are winemakers who grow (sometimes exclusively) PIWI grape varieties.
A board meeting of the organization was held on Friday morning, followed by a visit to Rebschule Freytag, which is one of the main suppliers of these resistant grape varieties, giving participants an insight into their work and interesting information about breeding and propagation (Figure 1).

Viticulture must respond to climate change
A large number of members of the "PIWI International" association from Germany, Austria, the Czech Republic, Switzerland, Italy, Poland and the Netherlands met last weekend in Neustadt an der Weinstrasse for the annual general meeting. Most of them are winegrowers who (sometimes even exclusively) grow new grape varieties that are resistant to powdery mildew and downy mildew, among other things. This means that treatment with pesticides can be significantly reduced, which is good for the environment and lowers the costs for the winemaker.
Big investment at Kullaberg – new winery for 100,000 bottles
While the harvest was still in progress, Scandinavia's most serious investment in wine production was inaugurated - a new winery at Kullabergs Vingård with a capacity for 100,000 bottles per year.
– Beverage is an important part of Skånes gastronomy, and it is important that we have people who dare to invest and work hard, said governor Anneli Hulthén, who cut the blue and yellow ribbon.
The building, planned since 2017 with construction starting exactly two years ago, resembles a typical quadrilateral local farm and, like everything else in the business, has an environmental focus.
– With a frame made of glulam and walls made of solid wood, we live up to our requirements for sustainability, said architect Paulina Berglund, also part of the owner couple behind Kullabergs Vingård.
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.

Status of acreage of PIWI varieties in Czech vineyards
At the end of the 2021/2022 wine year, according to the wine register, there were more than 17,900 ha of vineyards in the Czech Republic, of which almost 900 ha (896 ha) were planted with PIWI varieties, ie 5.0 %. The development of the area under cultivation of the PIWI varieties since 2012 is roughly represented by a growth line (Figure 1). In the last ten years, the area under cultivation has increased fivefold, and around 75 hectares are replanted every year.
Medals are almost becoming commonplace for Fredholms Vingård in Sweden.
They have only 1800 vines and got 96 points at PIWI International Challenge 2022 for their Solaris ”Elsa” – one of ten wines awarded Top Gold.
Medals are almost becoming commonplace for Fredholms Vingård in Sweden.
– It is the first time that we are submitting wine to a competition solely for PIWI. Previously we’ve wanted to compare ourselves to other wines, says Pär Fredholm at Fredholms Vingård.
The wine „Elsa“, a 100% Solaris that was first released in 2017, has previously been awarded four great golds, five golds and one silver at competitions in Spain, Germany and France. The wine has a couple of days of maceration with one third in French oak barrels before final aging for seven months in steel tanks.
– Internationally, „Elsa“ has always received over 90 points. It’s amazing that it can performs so well everywhere, all the time. Why? I think that part lies in the minerality, the saltiness and the high pH – the acid never becomes aggressive, says Pär Fredholm.
Fredholms Vingård is located, like most wineries in Sweden, in Skåne in the very south. The couple Jenny and Pär Fredholm started in typical Swedish manner on a small scale with red grapes. 25 Rondo cuttings were planted in 2002. Pär Fredholm shakes his head:
– Rondo is not our favorite grape, but at the time everyone here wanted to make red wine. However, it didn’t take long before people realized that the wine from Rondo was not that good, but that white was better suited.
However, he is much more fond of Siramé, which he hopes will get more attention in Sweden.
– It’s a fantastic grape that rarely gets sick. It’s a shame it isn’t more popular. We use it in our rosé together with Rondo, where the latter works better.
Fixed focus is Solaris. The first cuttings were planted in 2008, but it is only from vintage 2017 – the premiere vintage of the prize-winning wine „Elsa“ – that they think they have gotten to know the grape and know how to treat it.
– We prune hard for low yield, around 0.8–1 kilo per log. In the winery, we let the grape skins macerate for a couple of days before fermentation, partly to raise the pH value. Acid is indeed the backbone of all wines, but it can also be the winemaker’s worst enemy.
The 2022 harvest has just finished, and Pär and Jenny Fredholm are satisfied with the vintage, which, however, got off to a tentative start with a cold spring and early summer.
– Then came the heat – but no rain, so some here had problems with stress in their vines. Ours could handle it, so we got a normal maturity and about 13 degrees alcohol, says Pär Fredholm.
Though, he emphasizes the importance of not only looking at Oechsle. You have to look at the whole, not least the phenolic maturity.
To return to „Elsa“ and the structure behind the success. The typical saltiness and minerality – call it energy – which only seems to become more and more prominent, Pär Fredholm finds the answer in the soil. The vineyard has volcanic soil and is located near an old lime quarry.
– Now the roots are starting to dig deep and can reflect the terroir.
And why the name Elsa? After their beloved black labrador of course, always present in the vineyard to contribute positive energy to vines as well as followers on social media.
PIWI is developing into a quality mark - PIWI Wine Challenge 2022
High level at the PIWI International Wine Challenge 2022
Gone are the days when PIWI vines were grown primarily for environmental reasons. There are now many very good wines made from PIWI varieties, as well as numerous internationally committed winegrowers who can draw on a lot of experience with PIWIs both in viticulture and in winemaking and who bottle the best wines, which the PIWI International Wine Challenge 2022 has fully confirmed . Two thirds of the wines received SILVER or GOLD, even TOP GOLD. The high quality was generally confirmed by the visitors at the subsequent public tasting, for which all the wines were presented according to the blind evaluation. The PIWI mark, which PIWI members are allowed to put on the labels of their wines, can be considered something of a quality mark. And so PIWI wines bring environmental protection and enjoying good wines together and can be considered an important future of wine.
