- ... BACKGROUND AND AIMS: Climate change is advancing grape ripening and decoupling sugar and phenolic maturity, impacting wine typicity. The aim of this study was to test whether late leaf removal (LLR) under different watering regimes delayed harvest of two Spanish red cultivars in a semi‐arid and temperate‐warm climate. METHODS AND RESULTS: In two trials carried out in eastern Spain with the Bobal a ...

- ... BACKGROUND AND AIMS: Hyperspectral imaging (HSI) is used to assess fruit composition mostly indoor under controlled conditions. This work evaluates a HSI technique to measure TSS and anthocyanin concentration in wine grapes non‐destructively, in real time and in the vineyard. METHODS AND RESULTS: Hyperspectral images were acquired under natural illumination with a VIS–NIR hyperspectral camera (400 ...
