Haplotype-resolved genome assemblies of Chasselas and Ugni Blanc

Red wine is a beverage with one of the highest polyphenol concentration, which are extracted during the maceration step of the winemaking process.

Sauvignon blanc was first planted in Marlborough, New Zealand in the mid-1970s. Since that time, Marlborough has gained an international reputation by producing the definitive wine style of that grape variety.

In the pursuit of more sustainable viticulture, many winegrowers have drastically reduced nitrogen (N) fertilisation and abandoned chemical weed control in favour of permanent grass cover.

Lugana wines are made from Turbiana grapes. In recent times, many white and rosé wines are bottled and stored in flint glass bottles because of commercial appeal. However, this practice could worsen the aroma profile of the wine, especially as regards the development of volatile sulfur compounds (VSCs). This study aims to investigate the consequences of exposure to light in flint bottles on VSCs profile of Lugana wines fermented with two different yeasts and with different post-fermentation residual nitrogen.

Grape downy mildew, caused by the oomycete Plasmopara viticola, is one of the major diseases threatening the viticulture industry.
