El presente estudio tuvo como objetivo realizar un análisis comparativo de las características fisicoquímicas y sensoriales de tres vinos artesanales de mora elaborados en las localidades de Caño Zancudo (Vino 1), El Valle (Vino 2) y La Azulita (Vino 3), del estado Mérida, Venezuela. La evaluación se centró en determinar su calidad y conformidad con la normativa nacional venezolana. Se midieron parámetros clave como grado alcohólico, acidez total y volátil, extracto seco, contenido de taninos, azúcares reductores y totales, y concentración de metanol. Además, un panel de 41 catadores semientrenados realizó una evaluación sensorial de las muestras. Los resultados mostraron diferencias significativas entre los vinos. Aunque todos cumplieron con el rango de grado alcohólico estipulado por la Norma COVENIN 3042, los tres vinos presentaron niveles de extracto seco muy superiores a los permitidos por la Norma COVENIN 3287, lo que evidencia deficiencias en la estandarización de los procesos de producción. El Vino 2 presentó un defecto grave debido a su alta acidez volátil (3,03 g/L), superando el límite permitido por la Norma COVENIN 3286 y generando rechazo en la evaluación sensorial. El Vino 3 obtuvo la mejor aceptación, con 67,04 puntos y preferencia del 75,61% del panel, destacando por su equilibrio sensorial. El estudio resalta la necesidad de mejorar y uniformar los métodos de producción artesanal para asegurar la calidad y seguridad de estos vinos.
This study aimed to conduct a comparative analysis of the physicochemical and sensory characteristics of three artisanal blackberry wines produced in the towns of Caño Zancudo (Wine 1), El Valle (Wine 2), and La Azulita (Wine 3), in the state of Mérida, Venezuela. The evaluation focused on determining their quality and compliance with Venezuelan national regulations. Key parameters such as alcohol content, total and volatile acidity, dry extract, tannin content, reducing and total sugars, and methanol concentration were measured. In addition, a panel of 41 semi-trained tasters performed a sensory evaluation of the samples. The results showed significant differences among the wines. Although all complied with the alcohol content range stipulated by COVENIN Standard 3042, all three wines presented dry extract levels far exceeding those permitted by COVENIN Standard 3287, indicating deficiencies in the standardization of production processes. Wine 2 presented a serious defect due to its high volatile acidity (3.03 g/L), exceeding the limit permitted by COVENIN Standard 3286 and resulting in rejection during the sensory evaluation. Wine 3 received the highest score, with 67.04 points and a preference of 75.61% of the panel, standing out for its sensory balance. The study highlights the need to improve and standardize artisanal production methods to ensure the quality and safety of these wines.
