Flavor Enhancement Of Neutral White Wines By Mango Peel Products


Varietal flavor is commonly known as the aromatic character of a wine in which the aroma of a particular grape variety predominates. However, not all varieties present particularly pronounced aromas. Therefore, different methods are constantly sought to enhance the aroma of wines with neutral aromatic characteristics, such as the use of glycosidases (1), certain yeast strains (2) or maceration with different agricultural products. In this work, aiming to improve the sensory profile together with the diversification of this product, white wines, derived from a neutral grape variety, were elaborated with the addition of mango peel by-products. This by-product was chosen because of its greatly esteemed tropical scents (3). Three different samples were performed regarding the mango peels application: 7 days co-fermentation (MCF), 7 days maceration post-fermentation (MPF) and no mango peel added, considered as control (C). A comprehensive analysis of the volatile profile, both qualitative and quantitative, was carried out by SPE extraction followed by GC-MS. Wines were also tasted by a panel of experts in order to evaluate the sensory attributes. Conventional analsysis including color parameters were also executed. Preliminary results have shown that MCF and PCF, exhibited an overall terpene compounds increase in which significant amounts of characteristic mango volatile compounds such as 3-carene or p-cymene were found, which evoque floral-resinous aromatic scents. On the other hand, less appreciated compounds such as 1-octen-3-ol (musty odour) were also found in larger quantities in both samples treated with mango peels.  The sensory analysis outcomes showed that, while some unattractive volatiles compounds were identified in the samples treated with mango peels, those were not found in any case during the tasting evaluation. In addition, judges detected exclusive attributes in MCF and PCF samples, defined as compote and apricot notes. Furthermore, these exclusive desirable attributes remained much longer in the mouth in the sample of wines that had undergone post-fermentation maceration (PCF).In conclusion, together with the rest of data analysed, a 7-day post-fermentation maceration with dried mango skins is proposed as a natural cheap and simple aromatisation method for white wines.

Characteristics of ecological production of grape and wine in Prizren’s vineyard territory in Yugoslavia

Prizren’s vineyard territory-y assigned for ecological production of grapes and wine includes 1. 200 hectares of vineyard located in five separate localities which belongs to the P KB “Kosovo vina”, Mala Krusa in Prizren. Division of vineyard territory in zones was carried out in 1974. Pertaining to the vineyards, the climate and soil conditions have been studied and determined as well as topographie establishing of vineyard boundaries.

Effect of terroir and winemaking protocol on the chemical and sensory profiles of Pinot Blanc wine

Wine research in the past years has mainly been focused on laboratory scale due to the possibility of controlling winemaking variables. Conversely, studies on wine quality in relation to the winemaking variables at the winery scale may be able to better account for the actual challenges encountered during wine production. Winemaking problems are recently arising from progressive changes in environmental conditions in relation to the terroir. It is important to realize that each wine region may have specific winemaking protocols and that winemakers often base their decisions on subjective, emotional, and empirical opinions. Due to all the above-mentioned issues, taking the correct decision in winemaking to achieve the desired goals may become even more challenging.

Geochemistry of Vrbničko Polje (Croatia) winegrowing site

A multi-element pedo-geochemical survey was carried out in Vrbničko polje vineyards on the Krk Island, Croatia. This Mediterranean winegrowing site is famous by Žlahtina wine production.

Soave beyond the zonation

In a previous zoning program (1998-2002), climatic and pedological factors were able to distinguish 14 terroir within the Soave DOC area where wine characteristics are well recognizable. Nevertheless, in the past vinegrowers identified several vineyards where a better quality of the grapes and wines could be obtained. So, « beyond the zonation » will aim to suggest a new methodology to characterise the Cru, starting with 15 vineyards that were selected in the Soave Classico DOC area. In the year 2005, a meteorological station was positioned in each vineyard and temperature data were collected; because of the limited area of investigation, only 3 rain sensors were set up.

Dynamic agrivoltaics, climate protection for grapevine driven by artificial intelligence

The year-on-year rise in temperatures and the increase in extreme weather events due to climate change are already having an impact on agriculture. Among the perennial fruit species, grapevine is already negatively impacted by these events through an acceleration of its phenology, more damage from late frosts or through an increase in the sugar level of the berries (and therefore the alcoholic degree of the wine) and a decrease of acidity, impacting the wine quality. Sun’Agri, in partnership with INRAE, Chambre d’agriculture du Vaucluse, Chambre d’agriculture des Pyrénées-Orientales and IFV, developed a protection system based on dynamic agrivoltaics to protect grapevine. It consists of photovoltaic solar panels positioned above the crop, high enough not to impede the passage of agricultural machinery, and tiltable from +/- 90° to adjust the level of shading on the vineyard. These smart louvers, driven by artificial intelligence (physical models & plant growth models), are steered according to the plant’s needs and provide real climate protection.
