The management of oxygen during winemaking and aging is a big issue in order to achieve high quality wines. The correct amount of O2 improves aroma, astringency, bitterness and color, however an excess of oxygen promotes the appearance of yellow
Proceedings of Enoforum Web 2021
The Enoforum is organized by VINIDEA and is the largest technical-scientific annual congress in Europe for the wine sector. In February 2021, the selected works covered a wide range of innovative topics for the wine industry, such as using of artificial intelligence and precision approach for vineyard management, copper reduction strategies, new varieties dealing with the adversity of climate changes, use of ultrasounds in winemaking, new methods for tannin estimation and quantification of phenol content, different tools for wine authenticity.

Wine quality may be compromised by mouldy off‒flavours related to cork taint. Although different compounds are considered to be involved in this wine defect, haloanisoles (HAs), and among them the 2,4,6-trichloroanisole (TCA), are claimed as the main responsible.
In this work, an innovative analytical method has been proposed for fast and reliable in-line analysis of tannins in wines; the method is fast, does not require sample preparation and is based on the selective reactivity of tannins in a mixture containing proteinaceous matter (i.e. gelatin), under pH 3.5, resulting in the formation of white cloudiness.
In the oenological industry, the maintenance and sanitation of oak barrels has become a fundamental task. The wood has a porous structure that facilitates the penetration not only of the wine, but of the microorganisms it contains, such as the alterative yeast Brettanomyces bruxellensis.
