The wine microbial consortium: a real terroir characteristic

Abstract

Yeast, bacteria, species and strains play a key role in the winemaking process by producing metabolites which determine the sensorial qualities of wine. Therefore microbial population numeration, species identification and strains discrimination from berry surface at harvest to storage in bottle are fundamental. The microbial diversity and significance of its variation according to vineyard and cellar have not really been thoroughly considered in literature, and is the focus of this work. That should be of great interest because the spontaneous microbial population dynamics associated with a wine producing estate provide information on what might be considered as the method to obtain specific terroir typed wine. The both use of conventional microbiological methods numbering the wine microbial populations and efficient molecular tools of species identification and strains discrimination has demonstrated the microbial differences according to the estate revealing the microbial part in specific terroir characteristic.

Vintage by vine interactions most strongly influence Pinot noir grape and wine composition in New Zealand

Vine genetics, fruit maturity, region and vineyard are perceived as factors that strongly influence Pinot noir grape and wine composition. Our study aims to understand the relationship between grape (and ultimately wine) composition and the physical appearance and performance characteristics of a vine (i.e. vine ideotype). Our experimental approach controlled these variables by

Il paesaggio delle alberate aversane ed il vino Asprinio

Nel corso del 2009, in alcuni vigneti allevati ad alberata in provincia di Caserta (Italia), è stata avviata una ricerca per valutare la variabilità genetica della popolazione del vitigno ‘Asprinio’, la condizione sanitaria delle piante e le caratteristiche del vino sia rispetto alla forma di allevamento (alberata tradizionale e controspalliera) che all’altezza della fascia produttiva.

Algae protein: fining agent for white wine, sustainable, non-allergenic and animal-free

The development of non-animal and non-allergenic alternatives to traditional protein fining agents used in winemaking is of critical importance in order to ensure consumer safety and production sustainability. This study evaluates the effect of protein extracted from three types of algae (spirulina, chlorella vulgaris and tetraselmis chuii) as fining agents on the polymeric proanthocyanidin content responsible for astringency, as well as their effect on the colour, phenolic composition and volatile aroma of two white wines (a and b).

Genetics of adventitious root formation in grapevines

Commercial grapevine propagation relies on the ability of dormant wood material to develop adventitious roots.

Eliminating Brettanomyces and lactic acid bacteria in wine: the potential of Ultra-High Pressure Homogenization (UHPH)

Ultra-High Pressure Homogenization (UHPH) is an innovative technology that can be seamlessly integrated at various stages of winemaking. Its application helps minimize or even eliminate the need for sulphites and other antimicrobial or antioxidant treatments, offering a faster and more sustainable alternative.
