Study of some sparkling wines obtained from local varieties of white grapes in the Cotnari vineyard

Abstract

Cotnari vineyard is one of the oldest vineyards in Romania with a long history in wine production, the first historical mentions of the Cotnari vineyard dating from the 14th century. The terroir conditions in this vineyard allow production of both still wines and, more recently, sparkling wines of the highest quality. The study aimed to obtain data on the sensory analysis of the following sparkling wines: Frâncuşă 2017 (V1), Frâncuşă 2018 (V2), Grasă de Cotnari 2017 (V3), Grasă de Cotnari 2018 (V4), Tămâioasă românească 2017 (V5), Tămâioasă românească 2018 (V6), and also their correlation with the results obtained from the physico-chemical analyses performed. The sensory analysis was performed in two stages (a series of sensory indices specific to sparkling wines obtained in the Cotnari vineyard were identified and then, a quantitative analysis, by allocating scores from 0 to 9 for the previously established indices). Regarding the physical-chemical analyses, the following parameters were of interest: alcohol concentration, total acidity, density, total dry extract and non-reducing dry extract, sugars, free and total sulphur dioxide.
