Cumulative effects of repeated drought stress on berry composition, and phenolic profile: Field experiment insights

This work aims at identifying the most appropriate marketing strategies to inform consumers of the global market about the added value of the wines of Friuli Venezia Giulia.

Nowadays, the use of food preservatives is controversial, SO2 being no exception. Microbial communities have been particularly studied during the prefermentary and fermentation stages in a context of without added SO2. However, microbial risks associated with SO2 reduction or absence, particularly during the wine aging process, have so far been little studied. The microbiological control of wine aging is a key issue for winemakers wishing to produce wines without added SO2. The aim of the present study is to evaluate the impact of different wine aging strategies according to the addition or not of SO2 on the microbiological population levels and diversity.

Sulfur dioxide is the most commonly used preservative for protecting wine against oxygen, whereby two molecules of total sulfur dioxide are consumed for each molecular of oxygen.

Protein stabilization is an important part of the winemaking process of white wines, and in this work we present the results of protein stabilization of different monovarietal wines (Xarel.lo, Chardonnay, and Muscat) by a continuous stabilizing filtration process using a column packed with zirconium oxide operating in a continuous regime in a closed loop at pilot scale.

Wine industry is an important economic activity in the World, generating significant quantities of residues, mostly known as grape pomace. This material is rich in many nutrients, as fiber, minerals and antioxidants substances, such as phenolic compounds. These nutraceutical properties of grape pomace could be harnessed for human or animal consumption.
