Fungus-resistant vines sound like a single promise. Drinkers then expect a single taste. That is the trap.
At San Michele all’Adige, Fondazione Mach’s PIWI tasting — covered by La Stanza del vino — put resistant wines beside ordinary ones across styles. Judges and guests saw pét-nat energy, dry still bottles, and sweeter finishes in the same room. The point was not a medal table for one grape. It was proof that resistance is a vineyard tool, not a flavour brand.
Mini-concept: PIWI means vines bred or selected to fight mildew with fewer sprays. That changes the farm calendar. It does not freeze the cellar into one recipe. Yeast, sugar, skin contact and bubbles still decide the glass. Treat “resistant” like “organic” — a method story, then taste what is poured.
Why young drinkers should care: climate and spray rules will push more of these grapes onto shelves. If you assume they all taste thin or “green,” you will skip bottles that might beat a random can on a real night. Taste first. Category second.
Keep the pattern: one Trentino room, many styles. Resistance fights fungus. It does not erase choice in the glass.
