Effect of environmentally friendly vineyard protection strategies on yeast ecology during fermentation

AIM: Currently, an increasing concern from governments and consumers about environmental sustainability of wine production provides new challenges for innovation in wine industry. Accordingly, the application of more-environmentally friendly vineyard treatments against fungal diseases (powdery and downy mildew) could have a cascading impact on yeast ecology of wine production.

Influence of coinoculation of L. plantarum and O. oeni on the color and composition of Tempranillo wines

AIM: The aim of this research was to determine the influence of performing malolactic fermentation (MLF) of Tempranillo wines by coinoculation with Lactobacillus plantarum or Oenococcus oeni and Saccharomycescerevisiae on the composition and color of the final wines in comparison with sequential inoculation with Oenococcus oeni and spontaneous MLF. METHODS: Around 1500 Kg of Tempranillo grapes from Pagos de Anguix winery (Anguix, AOC Ribera de Duero, Spain) were harvested at the optimal maturity

Effect of nitrogen content on fermentation kinetics and aroma profile of assyrtiko wine

Today, there is need to design, produce and label terroir wines, with unique organoleptic properties and more “attractive to consumers”. For this purpose, two Saccharomyces cerevisiae yeast strains (Sa and Sb) isolated during spontaneous fermentations were used for white wine production from the Assyrtiko grape of Santorini. A third commercial strain was used as control.

Screening of aroma metabolites within a set of 90 Saccharomyces strains

Currently, the main demand in the global wine market relies on products with unique flavour profiles, character, and typicity, and the metabolism of yeasts greatly influences the organoleptic properties of wines. Therefore, the natural diversity of Saccharomyces strains rises in interest over the last decade, but a large part of this phenotypic diversity remains unexplored
