Effects of In-Amphorae Winemaking on the Chemical and Sensory Profile of Chardonnay Wine
MetadataShow full item record
The high value of dry extract and volatile acidity could statistically differentiate (P ˂ 0.05) the Chardonnay wine obtained in amphorae with maceration and stored for six months from the wine obtained in barrels and barriques, as evidenced by the analysis of variance. Similarly, the principal component analysis showed that all the amphorae wines sampled between November and March (not the wine analyzed immediately after alcoholic fermentation) were clearly differentiated from the analogue barrel and barrique wines due to the high volatile acidity, straw colour, and tannic perception. The Chardonnay wine produced in amphorae was characterized by a spicy flavour, pleasant tannic and a less ‘green’ character than wines from barrels and barriques, but showed a weak varietal aroma. Thus, the commercial offer of finished wines based on Chardonnay grapes can be potentially extended by including a product processed in amphorae.
