¿Qué son las variedades resistentes o piwis?

There are varieties called "resistant" that are actually tolerant to powdery mildew and downy mildew. I'll tell you the secret about them, what you can expect from them, and what other ways we have to create or seek resistance in our vineyards. Aside from the controversies, I analyze the topic from a purely technical point of view, so that each person can decide whether or not they want to use them; your production model will depend on that. This and much more in my daily email. Subscribe here: https://www.julioprieto.es/landing-pa...
