Leaf elemental composition in a replicated hybrid grape progeny grown in distinct climates

“Côtes du Rhône”, like many other controlled appellation wine, represents high stakes in the economical, social cultural and historical domains. The scenery formed by vineyards reveals these cultural values. It offers by a pleasant and appealing environment for the inhabitants and the tourists. It is also a powerful marketing tool for the winemakers.

Interspecific hybrid winegrapes are of growing interest in the context of climate change based on their disease resistance and cold hardiness. In addition to a need for increased understanding of their chemical composition, there is little empirical evidence on the consumer perception of non-vinifera wine. Phenolic compounds, and particularly color, play an important organoleptic and quality determination role in wine, but can vary significantly in interspecific hybrid wines compared to wines produced from Vitis vinifera cultivars [1, 2, 3]. Anecdotally, the variation in anthocyanin species, interactions, and concentrations in interspecific hybrids could result in a variance from“vinifera-like” wine color.

‘White Riesling’ is the flagship grapevine cultivar of the Rheingau region. However, due to climate change, its cultivation faces increasingly challenging conditions, including drought stress, high solar radiation, and heightened pathogen pressure.

Las uvas aromáticas se pueden dividir en dos clases, Moscateles y Malvasías, dependiendo del hecho de que el linalol o el geraniol, respectivamente, sean los alcoholes terpénicos monohidroxilados que

Consumption of wine/alcoholic beverages remains a topic of great uncertainty and controversy worldwide. The term “no safe level” dominates the media communication and policy ever since population studies in 2018 [1,2] were published, which denied the existence of a J-curve and suggested that ANY consumption of an alcoholic beverage is harmful to health. The scientific evidence accumulated during the past decades about the health benefits of moderate wine consumption, were questioned and drinking guidelines considered to be too loose.
