Water is the most abundant active compound in wine!

Wine flavor results on complexes interactions of odorous components, which come from different aromatic families like esters, thiols, aldehydes, pyrazines or lactones.

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. 

Atmospheric carbon dioxide (CO2) concentration has continuously increased since pre-industrial times from 280 ppm in 1750, and is predicted to exceed 700 ppm by the end of 21st century. For most of C3 plant species elevated CO2 (eCO2) improve photosynthetic apparatus results in an increased plant biomass production. To investigate the effects of eCO2 on morphological leaf characteristics the two Vitis vinifera L. cultivars, Riesling and Cabernet Sauvignon, grown in the Geisenheim VineyardFACE (Free Air Carbon dioxide Enrichment) system were used. The FACE site is located at Geisenheim University (49° 59′ N, 7° 57′ E, 94 m above sea level), Germany and was implemented in 2014 comparing future atmospheric CO2-concentrations (eCO2, predicted for the mid-21st century) with current ambient CO2-conditions (aCO2). Experiments were conducted under rain-fed conditions for two consecutive years (2015 and 2016). Six leaves per repetition of the CO2 treatment were sampled in the field and immediately fixed in a FAA solution (ethanol, H2O, formaldehyde and glacial acetic acid). After 24 h leaf samples were transferred and stored in an ethanol solution. Subsequently, leaf tissue was dehydrated using ethanol series and embedded in paraffin. By using a rotary microtomesections of 5 µm were prepared and fixed on microscopic slides. Subsequent the samples were stained using consecutive staining and washing solutions. Afterwards pictures of the leaf cross-sections were taken using a light microscope and consecutive measurements were conducted with an open source image software. Differences found in leaf cross-sections of the two CO2 treatments were detected for the palisade parenchyma. Leaf thickness, upper and lower epidermis and spongy parenchyma remained less affected under eCO2 conditions. The observed results within grapevine leaf tissues can provide first insights to seasonal adaptation strategies of grapevines under future elevated CO2 concentrations.

The role of soils and bedrock geology has long been acknowledged as a fundamental component of terroir. In South Africa the influence of geology is misunderstood and some important geological components will be highlighted in this paper.

The global warming phenomenon involves the frequency of extreme meteorological events accompanied by a change in rainfall distribution. Irrigation frequency (IF) affects the spatial and temporal soil water distribution but its effects on the phenolic composition of the grape have been scarcely studied. The aim of this work was to evaluate the effects of four deficit irrigation frequencies of 30 % ETo: one irrigation per day (T01), two irrigations per week (T03), one irrigation per week (T07) and one irrigation every two weeks (T15) on berry phenolic composition at harvest.
