Studies on some still wines obtained by the blanc de noirs method

Abstract

Consumer interest in innovative wines has increased in recent years in Romania, in correlation with the development of the wine sector. Nowadays, the winemaking technique proposed by Dom Perignon (blanc de noirs) with applicability to sparkling wines is increasingly used to obtain still wines. This research aimed to identify the most suitable technology for obtaining white wines from Fetească neagră and Busuioacă de Bohotin grapes. The resulting wines were analysed from physical-chemical and chromatic points of view, and their sensory properties and volatile compounds content were also registered. The obtained samples had characteristics usually found in wines obtained from white grape varieties. Although frequently used in the production of base wine for sparkling wines, this technique can give original results in obtaining still wines as well. The use of activated carbon has led to the production of wines with a higher commercial value (improved colour characteristics). Given that red wines are significantly less consumed compared to white ones, this technique allows the use of black grape varieties and the production of innovative white wines.
