Domestication has been giving us huge nutritional benefits but the genetic diversity decreased a lot compared to wild populations. That is why, while we develop new cultivars, preserving their wild relatives is important, as they can be a reservoir of useful traits to cross with

🙋🏽‍♂️Graft union matters!: grafts should be fully healed, not overgrown and not able to be broken by “moderate” pressure applied by the thumb! check a representative sample before planting my dear grower #grapevine #grafting #rootstock

Although #esca is the most visual #GTD, it doesn’t mean it is the most common. #Eutypa dieback threatens the #Sustainability of #viticulture in northern Spain every single year. Rainy winters help! 👇🏼 #Navarra #LaRioja

Cognac’s star grape, Ugni blanc, which accounts for 98% of the vines in the Cognac region, is ripening quicker and losing acidity as summers become hotter and drier. theguardian.com/world/2020/m…

Marzo es el mes en el que se realiza el injerto de los vinos en el campo. En #MarquesdeRiscal continuamos con el sistema tradicional de injerto, eligiendo las mejores variedades de tempranillo y graciano, que nos permite mantener un absoluto control sobre la calidad de la uva.
