Impacts of fumaric acid addition at the bottling on Cabernet Sauvignon wine quality. Comparison with tartaric acid addition.

Abstract

Climate change and reduction of inputs are two major challenges for viticulture and oenology. With increasing temperature, wines become less acid and microbiologically less stable (1). Thus, their pHs have to be lowered to avoid higher doses of sulfur dioxide (SO2) for their stabilization, which is against input reduction. Chemical acidification through tartaric acid (TA) addition is one of the most common solutions in the OIV countries members. However, with its high acidifying power, its bacteriostatic properties (2) and its low cost, fumaric acid (FA) could be a good candidate for both chemical acidification and stabilization of low acid wines. Nowadays, the effects of FA addition on red wine quality during the aging are not documented. Thus, this study aims to evaluate the impact of FA addition over the years on the quality of a Cabernet Sauvignon red wine. Here, we present results after six months of wine storage at 15°C.
For this, a sulfite free wine from Cabernet Sauvignon grapes was divided in two batches. One batch was sulfited at 80mg/L (S) and the other one remained non-sulfited (NS). Both batches were treated with FA or TA at two different concentrations (1.25 g/L or 2.5g /L eq. TA). S and NS controls were not acidified. Classical oenological parameters (pH, titratable acidity), color parameters (color intensity, CIELAB), total phenolic compounds (IPT, Folin, total anthocyanins and total tannins), antioxidant capacities (DPPH, CUPRAC) were analyzed after bottling and six months later. FA-acidified wines were compared with controls and TA-acidified wines regarding all parameters. Sensory analyses were also performed on wines.

Il Cabernet di Atina dal 1850 al giorni nostri: un esempio di valorizzazione del territorio

In the province of Frosinone from 1850 they are cultivated in some zones wine grape of French origin like Merlot, Cabernet franc Cabernet sauvignon, Sirah, Pinot noir. The insertion of these varieties was the work of Pasquale Visocchi in the great company of family “Fratelli Visocchi Proprietari” (F. V.P.).

Using image analysis for assessing downy mildew severity in grapevine

Aim: Downy mildew is a crucial disease in viticulture. In-field evaluation of downy mildew has been classically based on visual inspection of leaves and fruit. Nevertheless, non-invasive sensing technologies could be used for disease detection in grapevine. The aim of this study was to assess downy mildew severity in grapevine leaves using machine vision.

AN AUTOMATIC CANOPY COOLING SYSTEM TO COPE WITH THE THERMAL-RADIATIVE STRESSES IN THE PIGNOLETTO WHITE GRAPE

In recent years characterized by hot dry summers, the implementation of innovative irrigation tools in the vineyard represents a crucial challenge to ensure optimal production and to avoid excess of water consumption. It is known that the grapevine reacts to multiple stresses – i.e., high temperatures and wa- ter shortage – through adaptive mechanisms that are detrimental to the yield. Furthermore, this condi- tion is usually aggravated by high solar radiation, which could negatively affect the phenolic composi- tion of the grapes. Therefore, a cooling system has been developed aiming to reduce bunches’ sunburn damage.

Influence of polysaccharide extracts from wine by-products on the volatile composition of sparkling white wines

In the production of sparkling wines, during the second fermentation, mannoproteins are released by yeast autolysis, which affect the quality of the wines. The effect of mannoproteins has been extensively studied, and may affect aroma and foam quality. However, there are no studies on the effect of other polysaccharides such as those from grapes. Considering the large production of waste from the wine industry, it was proposed to obtain polysaccharide-rich extracts from some of these by-products[1].

Influence of planting stock and training strategy on the development and productivity of Pinot noir grapevines

For cool windy climates and/or lower vigor site situations delays in vine development during vine establishment can result in a greater number of growing seasons to achieve full yield potential. Plant material and training strategies utilized are critical factors in promoting vine development and production that is appropriate to the site conditions. The objective of this study was to evaluate nursery planting stock and training strategies for their potential to achieved advanced vine development and yield.
