The potential carbon neutrality of sustainable viticulture

As discussed in the First Science & Wine World Congress is recognized the need of viticulture sustainable practices systems to respond to the challenges posed by climate change in terms of adaptation and mitigation. This post is about a paper recently published with the aim of helping the clarification about this issue. The study was carried out with the aim of quantify the actual impact on climate of sustainable practices applied to a grape-to-wine system in Italy. At the end, authors concluded that viticulture sustainable practices allow grapes production with a potential carbon neutrality without exacerbating climate change.

The Biochar challenge in viticulture; enhance grape production and mitigate the effect of climate change in Mediterranean area

The main goal of viticulture is to maximize grape yields, vineyards management includes repeated tillage, crop residues removal, strict weed and pest control treatments. Soil and climate are very important factors in viticulture. To preserve soil quality in the long term it is important an adequate soil management. This post relates the results obtained in a study carried out to evaluate the use of biochar amendment of a vineyard, assessing the impact on soil functionality, VOC emission and fertility.

Aromatic evolution of blanc de noirs sparkling wines made by traditional method during twelve months of aging on their lees

Winemaking process affects the sparkling wine volatile profile. In this post the authors report the results obtained in a study carried out to find out the effects of the second fermentation and aging on lees of sparkling wine. In this study, different techniques were applied in in sparkling wine, namely: gas chromatography/mass spectrometry/olfactometry and sensorial analysis. The results suggest that the fruity/floral nuances in sparkling wine are due to a few high-impact aromatic compounds, such as ethyl isobutyrate, isoamyl acetate, ethyl hexanoate, β-phenylethanol and diethyl succinate.

Psychological warfare in vineyards: Using drones and bird psychology to control bird damages to wine grapes

Bird damage to wine grapes is a significant problem across the globe. Different strategies were tried to reduce bird damage but an efficient one was not yet found. This post discusses the results obtained with the use of novel Unmanned Aerial Vehicle (UAV, more commonly referred to as drone) system incorporating bird psychology for efficient bird damage control. The UAV is equipped with a loud speaker broadcasting distress calls, as well as a crow taxidermy installed on the undercarriage that appears as captured prey. The experiments were carried out in vineyards around south-eastern Australia. The results show that this new strategy to protect vineyards from the birds is a promising one.
