Study of Spanish wine sensory analysis data over a 3-year period
This study presents an investigation based on sensory analysis data of Spanish wines with geographical indications collected over a three-year period. Sensory analysis plays a crucial role in assessing the quality, characteristics, and perception of wines. The trained tasting panel at Dolmar Laboratory, accredited for objective sensory evaluation of wines since 2016, has been tasting over 5000 wines. However, it is since 2021, when a computer application for tastings was developed, that the digitalization of data allows for detailed statistical analysis of the results.
The research focused on analyzing data from expert tastings conducted over the past three years, involving more than 2000 Spanish wines with geographical indications. The final compliance of the wines with the descriptions provided in the specifications was evaluated using the collected data. Subsequently, the attributes responsible for deviations that led to non-compliance were identified. Lastly, by examining trends, valuable insights on variations over time were obtained.
The study identified the specific attributes that contributed to non-compliance, pinpointing areas for improvement and potential adjustments in the winemaking process. This knowledge can assist winemakers in enhancing the quality and ensuring consistency in their products.
