SUMMARY:

Colour is a vital element in the perception of rosé wine quality and a decisive factor in consumer choices, although there is no consensus on the ideal hue. The growing interest in rosé wines reflects a change in consumer preferences, who are increasingly seeking high-quality products with attractive visual characteristics. Colour, being the first attribute noted in a sensory analysis, provides important information about the product, influenced by the grape variety, terroir, winemaking methods and ageing. Within this scenario, this research project aims to monitor the colour evolution in brut rosé sparkling wines produced by the Charmat method, using the CIELAB colour analysis system in comparison with conventional assessment techniques. The study will focus on brut rosé sparkling wines, fermented from an exclusive blend of the partner company. Essential oenological parameters such as pH, total acidity, free SO₂ and total SO₂ will be assessed based on standard analytical methods. The samples will be analyzed using a Shimadzu 1900 UV-visible spectrophotometer, measuring wavelengths of 420nm, 520nm and 620nm, as well as a colorimeter for objective color measurements, expressed in coordinates on a 360° circle.  The expected results aim not only to improve the quality and competitiveness of the Brazilian wine industry, but also to promote sustainable development and the appreciation of the national wine heritage, contributing to the emergence of new products and business models.
