The potential carbon neutrality of sustainable viticulture
By Maria Vincenza Chiriacò
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
Aromatic evolution of blanc de noirs sparkling wines made by traditional method during twelve months of aging on their lees

It is very important to increase tolerance to pathogens in conventional and biotechnology-assisted grapevine breeding programs. Both fungal and viral diseases cause losses in berry production, but also affect the quality of the final products. The introduction of genetic resistance is economically and environmentally desirable. This post describes the results of a study where grapevine plants expressing defense proteins, from fungal or plant origins, or of the coat protein gene of grapevine leafroll-associated virus 3 (GLRaV-3) were generated by Agrobacterium-mediated transformation of somatic embryos and shoot apical meristems.
The Biochar challenge in viticulture; enhance grape production and mitigate the effect of climate change in Mediterranean area
By Silvia Baronti, Francesco Primo Vaccari, Lorenzo Genesio, Anita Maienza
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.
