Vinetur reports on research modelling how Napa Valley winegrowers could respond economically to increasingly severe heat, comparing continued Cabernet Sauvignon production, shade cloth, switching to heat-tolerant Carignan and relocating production to Lake County. A 30-year net present value model suggested that keeping Cabernet unchanged was most economical under moderate heat, shade cloth became preferable as heat intensified, and changing to a more heat-resistant variety produced the strongest return under the most severe scenarios, while relocation performed worst. A survey of 308 US wine consumers also indicated temporary willingness to pay premiums for climate-adapted wines, particularly those protected by shade, suggesting that adaptation decisions involve both vineyard resilience and consumer perceptions.
