Since the early 2000s, warm vintages have followed one another in Valais. With a few exceptions (2004 and 2007), high\u2014sometimes scorching\u2014temperatures have become the norm. In light of this trend, meteorologists and agronomists are examining the consequences of climate change for Swiss viticulture. <\/p>\n\n
Valais has a major asset in the face of climate change: the richness of its grape varieties. From Pinot Noir to Chasselas, including indigenous varieties such as Cornalin and Heida, this diversity enables remarkable adaptation to changing conditions. <\/p>\n\n
To avoid Pinot Noirs that are too ripe or \u201ccooked,\u201d where they are planted becomes strategic. They are favoured on the left bank of the Rh\u00f4ne or at altitude, above 700 metres. This adaptation is all the more necessary as competition intensifies with other Swiss wine regions such as Schaffhausen or Lake Zurich, not to mention the elegant Blauburgunders of Germany\u2019s Rheingau, renowned for their freshness and fruit-forward character. <\/p>\n\n
The late-ripening variety par excellence, Humagne Rouge thrives on the finest slopes of Valais. Rising temperatures do not seem to slow its development\u2014quite the contrary. <\/p>\n\n
Savagnin Blanc, known locally as Heida, has exceptional adaptability. It can ripen at altitudes of up to 1,000 metres and produces expressive wines on both banks of the Rh\u00f4ne. <\/p>\n\n
A delicate and sensitive variety, Petite Arvine is as wary of overly fertile soils as it is of drought periods. It requires constant attention and precise expertise. With increasingly dry summers, it may become even more demanding, while remaining a true signature of Valais\u2019 vineyards. <\/p>\n\n
Fanciful and exclusive, Cornalin fully expresses itself on poor soils. Resistant to cold as well as extreme conditions, it nonetheless requires low yields to reveal all its elegance. If poorly controlled, it can produce less harmonious wines. <\/p>\n\n
Thanks to this exceptional diversity of grape varieties, Valais\u2019 vineyards have strong assets for adapting to climate change. This richness makes it possible to look to the future with a certain serenity, provided that common sense is applied and adaptation remains ongoing. <\/p>\n\n
However, the risks associated with extreme weather events must not be overlooked. Hail, frost or drought can still severely affect harvests and weaken winegrowers in the face of increasingly unpredictable phenomena. <\/p>\n","protected":false},"excerpt":{"rendered":"
