Wine shaking during transportation: influence on the analytical and sensory parameters of wine

Abstract

According to OIV reports, annual world wine consumption fluctuated around 240-245 mln hL over the past decade. The general market globalization has led to the situation when almost half of the consumed wine is exported to other countries. Of this volume, more than 60 mln hL are bottled still and sparkling wines.

Transportation of bottled wine involves temperature changes, shaking and vibrations. The impact of the two last factors on the wine quality is currently not well understood. Some experts consider wine to be a robust product that easily withstands such mechanical stress. Other wine professionals argue that transportation may affect the wine quality, especially of high price segment products. Moreover, there is a common belief that wine needs a few days of “rest” after transportation before its consumption.

In this study, we summarized the current knowledge about the impact of transportation on wine parameters. In addition, we conducted our experiment with rosé wines, which were subjected to transportation simulations. We used young and aged Pinot Noir wines to compare their sensitivity to mechanical stress. Wine bottles were placed horizontally in cartons and shaken periodically (2 hours per day) for 2 and 7 weeks. Then the wines were analyzed and compared to non-shaken control samples.

As a result of the experiment, differences were found in the following basic wine parameters between shaken and control samples: oxygen content in the bottle’s headspace; free SO2 level (after 2 weeks). The examination of wine aroma composition included the analysis of varietal (terpenes, C13-norisoprenoids) and fermentation aromas (esters, higher alcohols and acids), as well as low molecular weight sulfur compounds (H2S, MeSH, EtSH, etc). Only some of the studied compounds differed between the shaken and control wine samples. These variations did not considerably impact the overall perception of wine aromas. Thus, sensory analysis did not reveal significant differences between the shaken and control wines in triangle tests.

Another aspect of this work is related to the development of a physical model, which can evaluate the total energy transferred to a wine bottle during transportation. This concept can assist the wine industry as well as further research, as more studies are needed on the behavior of various wines during transportation. Thus, this model can be used to explain and compare the results of different experiments.

Vineyard Landscape in Vale dos Vinhedos: Pressure and Protection

The region with Origin Indication Vale dos Vinhedos (IPVV) is located in the cities of Bento Gonçalves, Garibaldi and Monte Belo do Sul. It was established in November 2002, through an act of Instituto Nacional de Propriedade Industrial, according to Resolução INPI Nº. 75, of 2000, and Law Nº. 9.279 of 1996. The changes on the grape growing and wine making in the last 15 years, with the expansion of grapevines Vitis viníferas cultivation, the installation of several modern family wine companies, making wine with competitive quality, among other aspects, have enabled the implementation of concepts of Geographical Indications.

ePROSECCO: Historical, cultural, applied philosophy analysis and process, product and certification innovation, for the “sustainable original progress and promotion 4.1c” of a historic and famous territory and wine

According to the algorithm “A step back towards the future 4.1C”, (Cargnello,1986a, 1987d, 1988a.b, 1991, 1993, 1994b, 1995, 1999a.e, 2000b, 2007c, 2008a, 2009d, 2013; and according to the principles of “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” of GiESCO (Carbonneau and Cargnello, 2003 2015, 2017), the historical, applied philosophy and productive analysis connected to the innovations and to the “Certification of the Universal Holistic MetaEthical Sustainability 4.1C” “indexed new global production model 4.1C” has always been fundamental, especially for the “Prosecco Territory” and for the “Prosecco Wine” to design and implement their synergistic future “Sustainable and Certificable 4.1CC” according to the principles of the “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” by the GiESCO (Carbonneau and Cargnello, lc, Cargnello et Carbonneau, 2007, 2018), and of the Conegliano Campus 5.1C. (Cargnello, lc). Nowadays, people think that Prosecco is a wine from the Veneto Region (from Conegliano and Valdobbiadene in particular), while it comes from Friuli‐Venezia Giulia Region (in North Eastern Italy, such as Veneto) more precisely from “Prosecco” in the Municipality of Trieste (TS‐Italy), as documented in 1382 and in 1548, when Pier Andrea Mattioli, described “that ancient wine, which is born in Prosecco”, as a wine with the following characteristics “thin, clear, shiny, golden, odorous and pleasant to taste». In 1888 at the “Wine Fair” of Trieste there were the “Sparkling wine Prosecco” by Giovanni Balanc, by Giuseppe Klampferer and that one by Marino Luxa. In the 19th century, many expressed their appreciation for the “Prosecco” of Trieste. In order to implement intra and extra territorial and cross‐border relations, as well as, the “Certification of: Products, Companies, Territory, Bio‐MétaÉthique District 4.1C” of Prosecco, a series of activities and researches were conducted in 8 companies: 5 in the “Territory of Prosecco” (TS) in which the principles of “Charter of Sustainable Viticulture BIO‐MetaEthics 4.1CC” of GiESCO (Carbonneau and Cargnello, lc) have been successfully applied. In particolar: 1‐ new and original “Sustainable 4.1C global production model” developed also to prevent the problems caused by wild boar, roe deer, and birds while safeguarding their “psychophysical wellness”, as well as the “psychophysical wellness 4.1C” of the macro and micro flora and fauna, of the biodiversity, of the landscape, etc. (Cargnello, lc), 1.2‐ chemical weed control and “Non MetaEthics 4.1C” processing with the total grass growing of the ground without or with mowing, better if it is manual to protect grass, air and soil, 2‐ recovery of “Historic”: land, vineyards, vines, biodiversity, landscapes, productions, products, … , 3‐ production of the famous “Prosekar, also rosé, of Prosecco” and “Prosecco di Prosecco”, according to “A step back towards the future 4.1C” 4‐ to offer a deserved psychophysical well‐being to the “Prosecco Territory” and entrepreneurs.
