- Viticultural Innovators
- Argue that disease-resistant genetics are the only viable path to truly sustainable, low-chemical winemaking in a warming climate.
- Oenological Researchers
- Focus on empirical data, demonstrating through chemical analysis and blind tastings that modern PIWIs achieve sensory parity with classic grapes.
- Traditionalists & Skeptics
- Express caution about abandoning centuries-old varietal names and worry about consumer willingness to embrace unfamiliar grapes.
What's not represented
- · Conventional agrochemical manufacturers
- · Everyday wine consumers unaware of the breeding process
Why this matters
Traditional winemaking relies heavily on chemical fungicides to keep vines alive, carrying a steep environmental cost. This new wave of naturally resistant grapes offers a blueprint for a cleaner, more sustainable agricultural future that protects both the soil and the climate.
