“…Study presented here in provided evidence that the spatial variability within the vineyard can be apparent in plant physiology and berry chemistry. Moreover, our results provided evidence that proximal sensing of soil EC may be a useful tool to connect soil to plant water status, even further to berry primary and secondary chemistry as observed in recent research (Bonfante et al, 2015;Tardaguila et al, 2018;Priori et al, 2019). This fundamental knowledge can contribute to a greater linkage between available sensing technologies and quality-related chemical analysis in precision viticulture research (Matese et al, 2015).…”

“…Based on the captured variability in vineyards, vineyard delineation can be utilized to minimize the variability between zones pairing with targeted agronomic practices (González-Fernández et al, 2017). Selective harvest is one example of these practices when fruits are picked differentially, or segregated into various batches prior to the fermentation for producing wine with different rankings or characteristics (Bramley et al, 2011b;Priori et al, 2019). This approach can coalesce the variable ripening stages that may occur within the vineyard, where the relatively unripe fruits would be imparting unripe characteristics in the final wines (Parr et al, 2007).…”

“…The synthesis of phenolic compounds in grapevines is of greater variability than that of other compounds, as the edaphoclimatic conditions during each year greatly affect their content in grapes. 22 There are many studies focused on the effect of particular factors of external environmental conditions on grape composition, such as sunlight, temperature and soil features, including texture, available water content, calcium carbonate content, rooting depth and viticultural management, 6,8,[22][23][24][25][26][27][28][29][30][31][32] but there are generally no studies concerned with the impact of soil type and properties on the anthocyanin quality in grapevine. The reason could be that soil types of a vineyard involve many factors which cannot be easily changed.…”

BACKGROUND Soil and climate are among the most determining factors for the composition of grapes. Among the compounds present in grapes, anthocyanins mainly determine their organoleptic and health‐related properties. The purpose of this work was to study the influence of three different soils on the anthocyanin content of Tempranillo grapes (Vitis vinifera L.) from 2016 and 2017 vintages. The soils of the vineyards were classified as Fluventic Haploxerepts (FH), Typic Calcixerepts (TC) and Petrocalcic Palexerolls (PP). RESULTS Non‐acylated anthocyanins, and those derived from malvidin and peonidin, were the most abundant in grapes, regardless of soil type and year. During the wetter season (2016), the grapes with the highest concentration of total anthocyanins and several of the major anthocyanins were those from TC and PP soils, in which nitrogen availability was lower than that in FH soil. However, during the drier season (2017), no significant differences were observed, although trends similar to those seen in the 2016 season were recognized. Principal component analysis showed a good separation of samples according to the two seasons and to the three soils in each season. CONCLUSION In vineyards that resemble each other closely and that are located in a unique mesoclimatic area where similar plant material is used and similar managements practices are applied, soil characteristics, which condition water holding capacity and nitrogen availability for the vines, in conjunction with seasonal conditions, were the factors that predominantly determined the anthocyanin composition in grapes. © 2019 Society of Chemical Industry

“…Somewhat confusingly, in wine science, this specific branch that does not include cultural or socio-economical aspects, is also referred to using the term terroir. Terroir de base (Deloire et al, 2005), or less confusingly, a "functional zone" is the smallest area where it is possible to objectively describe the effect of environment on plant physiology and agricultural production, and which could be differentially managed (Bramley, 2005;Acevedo-Opazo et al, 2008;Bonfante et al, 2015;Brillante et al, 2016a;Brillante et al, 2017;Priori et al, 2019;Bramley, 2020). The approach to studying relationships between terroir and wine peculiarities is scale dependent, as different factors influence agricultural choices and vine performance at the regional or the within vineyard level (Vaudour, 2002).…”

Terroir is a French term with roots in the Latin term terra meaning ground or land. In the international wine jargon, the term has assumed a more specific and nuanced meaning: it is the result of "collective knowledge of the interactions" between the environment and the vines mediated through human action and "providing distinctive characteristics" to the final product (i.e., wine; OIV, 2010). Terroir is not just a geographical site, but includes: (i) the physical environment (e.g., climate, geology, soil, and topography); (ii) the biological material and production practices; (iii) cultural, socio-economical and political aspects. Nowadays, the storytelling of terroir is abundant in both the popular press and marketing of wine. Although there is no reference to wine quality in the description of the terroir concept (OIV, 2010), wines which may be associated with a single vineyard are often deemed superior, although wines derived from multiple sites may also be highly regarded (Bramley, 2017). According to OIV, 2010, which should be considered an accepted definition, terroir is a loose interpretation of a protected designation of origin (PDO), thus questioning the need for a winespecific term. For example, in the regulation of the European Union (EC No. 510/2006 Art. 2.1(a), Council of the European Union, 2006), in order to benefit from PDO status, an agricultural product needs to: i) originate and be produced, processed and prepared in the defined geographical area and ii) have "quality or characteristics essentially or exclusively due to a particular geographical environment with its inherent natural and human factors." The concept of geographical origin can be used in all crops and foods, and PDOs are defined and regulated. Conversely, the terroir interpretation applies mostly to wine and is not regulated, which leaves it open to abuse and self-assessment without control, scientific evidence or socio-historical recognition (Matthews, 2016). As a result, in the current popular use, the term terroir has erroneously become jargon for vineyard site. A designation of origin is a strict regulation. In order to maintain characteristics related to the place and the traditional practices, PDO products are made according to production standards, and are evaluated before introduction to the market, to ensure conformity to the important and distinctive characteristics that are the reason for the designation. It should be clear that, when
