Vitigni alternativi e tutela della tipicità: uno studio indaga le prospettive
🍷 In response to climate change, France's historic wine regions are exploring grape variety modifications to sustain wine quality. Bordeaux researchers have evaluated 26 red varieties for potential inclusion in classic Bordeaux blends, notably Cabernet-Sauvignon, Merlot, Cabernet Franc, and Petit Verdot. Five candidates, including Fer Servadou, Duras, Manseng Noir, Vinhão, and Arinarnoa, could be added at 10% or 30% without significantly affecting wine typicality, except for Vinhão, which reduces typicality at higher proportions. Two sensory analysis tests with professional judges assessed the impact on Bordeaux wine typicality, considering strict regulatory varietal combinations for production. This research marks a step towards potentially introducing alternative non-native varieties to Bordeaux, with further studies needed on aging effects and vintage variations.
