Terclim 2026 – Session 3: Impacts of changing terroir components on product identity

Adaptation of viticulture to future climate scenarios includes the exploration of grapevine (Vitis spp.) rootstock varieties.

Empedrado is located in the coastal range of the Maule Valley and represents a distinctive viticultural ecosystem for the País variety.

Since 1935, grapes used to produce French AOC wines must come from a precisely defined area at the plot level.

In the wine industry, terroir’s concept connects environmental, biological and cultural factors with consumer perception and product identity.

Terroir influences winegrape production and thereby wine quality, style, product image, and ultimately the reputation of a region.

Climate change is shifting the timing and conditions of winegrape berry ripening, impacting development and composition (van Leeuwen & Darriet, 2016).

Water relations in vineyards are affected by microclimatic conditions, which impact the plant water status and the vine physiological response.

The grapevine (Vitis vinifera L.) is a drought tolerant crop species that can be cultivated without irrigation in dry climates, even with rainfall as low as 350 mm/year.
