Electrochemical approaches in wine analysis 


There is a high demand in the wine industry for analytical methods able to provide useful information to support the decision-making process in the vineyard and in the winery. Ideally these methods should be rapid (e.g. not requiring any sample preparation), cost-effective both in terms of required equipment and cost of analyses, and easy to implement. 



Electroanalytical methods have been successfully applied to the analysis of wine antioxidants, in particular phenolic compounds. However, until recently, their application was restricted to research laboratory settings, due to the complexity of the analytical set up and procedures. The recent advances in the development of portable equipment and screen-printed disposable sensors have provided interesting opportunities to adapt this technique to the winery environment.  



This lecture will cover different electroanalytical approaches of potential interest for the wine industry, with particular emphasis on voltammetric methods and their application to the monitoring of winery-relevant processes and parameters as well as for wine grade classification and varietal characterization. Additional possibilities will also be explored, in particular those related to the rapid classification of enological products such as commercial tannins or oak derivatives. Along with highlighting the benefits and drawbacks of the techniques presented, novel integrated approaches will be discussed. In particular, the combined use of advanced multivariate data analysis and artificial intelligence can unlock the capabilities of voltametric methods in the development of approaches of predictive enology. Among these, the possibility to develop tools for wine shelf-life prediction will be discussed

la caratterizzazione dell’areale viticolo “terre alte di brisighella”: aspetti metodologici e primi risultati

La zonazione viticola rappresenta un importante strumento di indagine per valutare e interpretare le potenzialità produttive e qualitative di un territorio. Con l’obiettivo di studiare come l’ambiente influisca sulla qualità dell’uva nell’areale di Brisighella, sono stati monitorati, nelle annate 2007, 2008 e 2009, 14 vigneti per la varietà Albana e 38 per la varietà Sangiovese, rappresentativi di una area vitata di circa 1000 ha.

The role of ampelographic collection in genetic improvement of native varieties and the creation new varieties

The available plant diversity is maintained in global genetic collections and germplasm banks. One of the main objectives of the study of the genetic material of vine still conducting research to characterize the genotypes and the creation of new varieties. The main ampelographic collection of the country, the largest in the Balkans, is located at the Athens Vine Institute in Lykovrisi, Attica, in an area of 70 acres. It contains more than 800 varieties, most of which are indigenous. The Institute is conducting research on the genetic improvement of native varieties and the creation new winemaking and table grape varieties of high productivity, grape quality, resistance to fungal diseases and their adaptability to stresses using the hybridization method using European high-quality varieties.

HPLC and SEC analysis on the flavonoids and the skin cell wall material of Merlot berries reveals new insights into the study of the phenolic maturity

Anthocyanins and tannins contribute to important sensorial traits of red wines, such as color and mouthfeel attributes.

Analysis of volatile composition of interaction between the pathogen E. necator and two grapevine varieties

Volatile organic compounds (VOCs) are emitted by nearly all plant organs of the plants, including leaves. They play a key role in the communication with other organisms, therefore they are involved in plant defence against phytopathogens. In this study VOCs from grapevine leaves of two varieties of Vitis vinifera infected by Erysiphe necator were analysed. The varieties were selected based on their susceptibility to pathogen, Kishmish Vatkana has the Ren1 resistance gene and Zamarrica showed high susceptibility in previous trials.

Application of a fluorescence-based method to evaluate the ripening process and quality of Pinot blanc grape

The chemical composition of grape berries at harvest is one of the most important factors that should be considered to produce high quality wines. Among the different chemical classes which characterize the grape juice, the polyphenolic compound, such as flavonoids, contribute to the final taste and color of wines. Recently, an innovative non-destructive method, based on chlorophyll fluorescence, was developed to estimate the phenolic maturity of red grape varieties through the evaluation of anthocyanins accumulated in the berry skin. To date, only few data are available about the application of this method on white grape varieties.
