At MOVIN Agency, we’re thrilled to explore what 2025 holds for the world of wine innovation. One of the most exciting trends to watch is the rise of PiWi grape varieties, which promise to reshape organic wine production. Here’s a deep dive into why these fungal-resistant hybrid grapes are becoming a buzzword in the industry, as showcased at ProWein 2024.
The Challenge of Fungal Diseases in Organic Viticulture
Fungal infections like downy and powdery mildew (Peronospera and Oidium) are persistent challenges in organic and biodynamic winegrowing. These fungi, introduced to Europe in the 19th century, have resisted eradication. While conventional producers spray their wines 7-8 times a season, organic growers often need 12 or more treatments due to their restricted options, leading to higher costs, more labor, and greater carbon emissions.
This is where PiWi grape varieties—short for Pilzwiderstandsfähige Traubensorten (fungal-resistant hybrid grapes)—come into play. Their natural resistance drastically reduces the need for treatments, requiring only 2-3 applications per season. The ecological, economic, and carbon footprint benefits are undeniable, with an estimated 80% reduction in required treatments.
Pioneers in PiWi Grapes
Swiss vine breeder Valentin Blattner has been at the forefront of the PiWi revolution, creating varieties like Cabernet Blanc, Cabertin, and Pinotin. These grapes not only combat fungal diseases but also enable winegrowing in colder regions previously deemed unsuitable for viticulture.
Austria is leading the charge, with producers like Winzer Krems and Weingut Geyerhof showcasing PiWi wines such as Donauriesling and Blütenmuskateller. In Steiermark, where PiWis make up 2.9% of plantings—double the national average—wineries like Ploder-Rosenberg are setting new benchmarks.
Expanding Horizons for PiWi Wines
In Germany, PiWi varieties account for 3.5% of total vineyard area, with approximately 10% of new plantings dedicated to them. Graf von Weyher in the Palatinate has been crafting wines from PiWis like Cabernet Blanc for two decades, while Solaris, a German-bred variety, is enabling viticulture in northern climates like Poland and Scandinavia.
Italy is also embracing PiWis, with renowned producer Roberto Anselmi experimenting with varieties like Aromera and Souvignier Gris. These efforts mark a significant step toward mainstream acceptance of these hybrid grapes.
A Brief History of Hybrid Grapes
While PiWis may seem revolutionary, their roots trace back to the 1860s Phylloxera crisis in France. Early interspecific hybrids aimed to combat the vine-destroying mite, with fungal resistance emerging as an added benefit. However, restrictive regulations and biases against non-Vitis vinifera grapes delayed their acceptance.
Today, attitudes are changing. While PiWis may not yet rival the greatest vinifera wines, they are producing high-quality, value-driven bottles that appeal to both producers and consumers.
The Road Ahead for PiWis
As sustainability and climate resilience take center stage in winegrowing, PiWi varieties offer a compelling solution. From Austria to Germany and beyond, these next-generation grapes are carving out a place in the global wine landscape. At MOVIN Agency, we can’t wait to see how this trend evolves and continues to shape the future of organic viticulture.
