Sviluppo vegetativo del Nebbiolo nell’area di produzione del Barolo DOCG: influenza sulla qualita’ della produzione

Abstract

Environment features and management operations on shoot and leaves modify the canopy during the vegetative season, changing the grapevine microclimate and the ratio between photo synthetic sources (the canopy) and productive sinks (the grapes). The aim of the present study was to evaluate on several vineyards the evolution in the season of the canopy development, in order to relate the vegetative behavior of the vine with the quality of grapes at harvest. For two consecutive years canopy development was assessed on 30 Nebbiolo vineyards in the Barolo area, using the point quadrat method. Size and structure of the canopy were assessed in June and September. Yield and qualitative characteristics of the must were determined at harvest. Total leaf area measured at the end of the vegetative season was directly correlated with yield, but it was not correlated with sugars and phenolic accumulation in the grape. However, both sugar and phenolic content in the must were proportional to the increase in canopy area observed between June and September, which is affected by plant vigor and vineyard management techniques (e.g. topping). The results suggest that the quality of Nebbiolo grapes in the Barolo area is affected by environment-induced vigor on one side, and by canopy management on the other side.

AOC valorization of terroir nuances at plot scale in Burgundy

In the highly competitive global wine market, Burgundy has a long-established reputation to maintain. The vine and wine sector in Burgundy is based on a five-level ranking of AOC (Appellation d’Origine Contrôlée) wines and of the plots where the grapes are grown.

Prosensorial potential of new fungi-resistant varieties in modern oenology

The introduction into the Italian wine supply chain of the latest generation of fungi-resistant grapevine varieties, endowed with a greater or lesser strong resistance to downy and powdery mildews, represents a valid tool of making viticulture more sustainable, particularly in northern regions of the peninsula, where climatic conditions accentuate the pressure of fungal diseases. However, the affirmation of resistant varieties is a function of their agronomic value, as well as of their oenological and sensorial value. The purpose of this study was to evaluate in detail the sensory potential of the new resistant varieties, in order to understand their real possibility of inclusion in the modern global enological context.

Vine growing description of Aeolian archipelago

An agroclimatic description of Aeolian archipelago viticulture area (Me), Italy is presented. Aeolian archipelago is located off the northeastern coast of Sicily and it includes the islands of Alicudi, Filicudi, Salina, Panarea, Lipari, Stromboli and Vulcano.

The colour pattern of flower arrangements influence wine tasters’ sensory description

The arrangements of flowers and wine counterparts are inextricably linked. Whether a fundamental aspect of tablescaping or acolytes to broader entertainment rituals, they have an entangled history since ancient times. The aim of this contribution is to verify the influence of visually delicate and robust flower arrangements on individual description of wines. Changes in the sensory description of wines were investigated during subjects’ (thirty-two participants) exposure to three different conditions: the presence of delicate, robust, or totally absent flower arrangements. In each condition, the same two wines were blind tasted: a wine previously defined as delicate – a Pinot Noir from Australia, and a wine known for its robust character – a Tannat from Uruguay.

Gastrointestinal digestion of wine sulphites and their effects on human gut microbiota

Sulphites are by far the most widely used additive in the wine industry. In relation to health, the interaction of sulphites with the gut microbiota has not been addressed so far. Following the consumption of wine and other sulphite-containing foods, the gastrointestinal tract and the microbiome are one of the first barriers that these compounds face in the human organism. In this study, we used a previously validated gastrointestinal digestion model (SIMGI®) [1,2] to evaluate the effect of intestinal digestion of wine sulphites on the gut microbiome.
