| Popis: | Sweet, semi-dry and semi-sweet red wine samples from two vine-growing regions in Romania: Vrancea and Recas were analyzed aiming to show their main chemical properties including heavy metal content, and, microbiological characteristics. The chemical analysis showed that the semi-dry wine (W1) has a high polyphenol content, permanganate index and content of Fe, Zn and Cu, but the lowest content of anthocyanins, sugar and Mn; the total acidity of semi-sweet wine W3 was the highest, while the semi-sweet wine W2 contained the highest concentrations of anthocyanins and SO2. No contamination with yeasts, molds and bacteria was found when opening the wine bottles, these colonies having grown one month after opening. The importance of this article comes from the comprehensive presentation of the connections among the physicochemical and microbiological characteristics of sweet to semi-sweet red wines, or to semi-dry from two vine-growing regions in Romania: Vrancea and Recas. |
