Consolidar los cultivares de uva para producción de vino en regiones cálidas debido a las fluctuantes temperaturas que les caracteriza en invierno, no es una tarea fácil, ya que no tienen las condiciones adecuadas para estos cultivos. Debido a tal circunstancia, se propuso el área del viñedo experimental del cipa-uanl, que tiene un clima semicálido, subhúmedo, con temperaturas promedio por arriba de los 15° C en la fase de endodormancia del viñedo, lo que la ubica por encima de las horas frío necesarias para una adecuada producción y calidad de uva. El cálculo del índice climático en el área se encuentra entre los 1100° a 1600° día calor. El ajuste de los datos de latencia invernal fueron polinomios de orden 5 con R2 por encima de 0.91. Los sólidos solubles totales necesarios para la vendimia se alcanzaron entre el 10 y el 20 de junio, con valores entre 21° y 25° Brix.

“…La uva debe estar bien madura para recolectarse, y aunque su contenido en azúcares no es el único criterio que se sigue a la hora de la vendimia, se busca que contenga más azúcar versus menos acidez, lo que influirá en el tipo de vino a conseguir (Colana y Royci, 2017).…”

The preference for the consumption of red wine in Mexico is increasing because its components derived from the grape are attributed to health benefits. The quality of wine depends mostly on the vineyard conditions. The objective of this study was able to differentiate the physicochemical composition in the harvest stage of four varieties of red grapes that are used in the production of wine to relate their maturation with those of their hyperspectral signatures. Various parameters including pH, total soluble solids, color, weight, and morphology were determined from the bunches of grapes. Concerning the maturity index, it was observed that the grapes with the highest degree of maturity were Shiraz and Merlot at harvest time. The pH of grape juice is a measure of active acidity; the texture is considered a quick and inexpensive technique. The hyperspectral signatures reflectances versus color, total soluble solids, morphology, weight, texture, and pH for each grape variety was best fitted with Gaussian curves of order 8 to Cabernet sauvignon and Merlot, 7 to Malbec, and 5 to Shiraz with R2 above 0.99.
