Muller-Koeberlé - Nat 327
The wine of tomorrow, today!
Domaine Muller-Koeberlé is taking Pét-Nat to a whole new level.
This is a refined, seriously crafted sparkler packed with fresh strawberries, zesty blood orange, and a soft, creamy mousse.
The trick? It's made from 50 different PIWI varieties, all interplanted in a single field.
But what is PIWI? They are fungus-resistant grapes created through traditional, manual crossbreeding—absolutely NO genetic modification!
Traditional vineyards, even organic and biodynamic ones, often require frequent spraying of natural fungicides like copper and sulfur to fight off mildew, especially in wet vintages.
PIWI varieties drastically change this dynamic:
• Fewer treatments: Up to 80% fewer fungicide sprays compared to traditional
grapes.
• Lower carbon footprint: Fewer tractor passes means less soil compaction and
significantly reduced fuel consumption.
• Healthier soils: Less copper buildup protects local microbial life and
groundwater.
While still a niche in the global wine market, PIWIs are gaining major traction in cooler,
wetter European climates where fungal pressure is highest.
A perfect reflection of Alsatian terroir and the future of sustainable winemaking.
