Strategies in vineyard establishment to face global warming in viticulture: a mini review

Different technological solutions are developing in the wine industry to mitigate the negative effects of the current global warming to mainly achieve wines with a lower alcohol content. These proposed solutions mostly act at the oenological level and are focused on intervening in the raw material to be transformed; that is, on reducing the concentration of sugar in the must using filtration techniques or also on wine dealcoholizing by physical processes. These techniques are intended to offer solutions and respond to new consumer expectations, but they may be considered too artificial to be widely accepted. In this way, viticultural strategies may offer a natural solution to obtain grapes with low sugar content, maximizing their quality by delaying ripening. This mini review surveys the viticultural strategies that can be applied in the establishment of a vineyard - that is, when it comes to planting of a new vineyard - such as vineyard altitude, latitude, orientation, and slope, as well as rootstock, variety, clone, training system, and row orientation and slope, with the aim to mitigate the negative effects of climate change on grape and wine quality and to delay grape maturation. Finally, we propose a ponderation of the strategies discussed to contextualize its importance to face global warming in viticulture. (c) 2020 Society of Chemical Industry
