Oak ageing sometimes results in a sweeter wine. Which oak compounds are responsible for this perceived sweetness, and under which circumstances are they released in the wine?

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

@BKPinot @fkerslake Looks very interesting, a shame it is not open access.

@alain_deloire Yes indeed, and it probably differs per grape variety. Please keep us posted about the growth of these vines!

@alain_deloire Aah, my bad, seeing all those green leafs i asumed you ment pruning the new shoots. Depending on during which growing stage you prune it may only delay the ripening. However, it does affect the reserves of the vine and when pruning too late, there will be no regrowth.

[WineScience @Wine_Science]

@wineecon What explaination would you give for this decline? China's own wine production?

[WineScience @Wine_Science]

@dbastidacaro @alain_deloire It is a study by researchers from Universidad de la Rioja

Milk and whey are used against powdery mildew. But what is their mode of action? How effective are they? And why are they not used widely in #viticulture?
