“…Nevertheless, the authors concluded that more testing was required to determine whether the differences can be perceived by less experienced consumers and how sensory attributes affect wine preferences. On the other hand, there are numerous works, conducted with different grape cultivars, which support the results of our study showing little impact of lighter pruning on wine quality attributes (Rousseau et al, 2013 ;Tomasi et al, 2013).…”

“…Some of the above-cited works also mention that light pruning produces more smaller-sized bunches and may modify must oenological characteristics. Nonetheless, the results vary in accordance with grapevine vigour and grape cultivar (Tomasi et al, 2013). Research done over the last 30 years has shown that there is a potential to develop integrated systems to stabilize the yield and quality of vineyards across seasons, but also that annual variability, largely dependent on environmental conditions, is much greater than that which can be achieved by modifying management practices (Clingeleffer, 2010).…”

Aim: Light pruning may improve vine yield and quality although vineyard responses are variable. We assessed the effects of traditional manual pruning and mechanical light pruning on the viticultural and oenological performance of Vitis vinifera cv. Bobal and cv. Tempranillo.Methods and results: During 2008-2011, Bobal and Tempranillo vineyards underwent traditional pruning or light pruning. The effects of both pruning techniques were determined in vine vigour and yield, and grape and wine characteristics. Both cultivars responded similarly to the pruning techniques assayed: i) light-pruned plants tended to overcrop, ii) grape yield significantly increased with light pruning and produced more clusters with smaller berries, and iii) the oenological characteristics of grapes were slightly affected since fruit ripeness was delayed in mechanically light-pruned vineyards.Conclusion: Mechanical light pruning vs. traditional manual pruning offers potential benefits: 30% higher yields; lower cluster and berry weights; a 40% reduction in pruning costs; and production of wines with lower alcohol while maintaining colour and phenolics.Significance and impact of the study: No detrimental effect of light pruning on grape characteristics was found, and the wines deriving from these grapevines offered good oenological characteristics. Mechanical light pruning may prove a suitable tool to prolong the vine vegetative cycle, which is reduced by the climate change in the Utiel-Requena region.

“…Table 8.2 shows, however, that the major influence on variability in cluster weight is the growing site; in fact, variability in cluster weight among the zones is higher than that among the growing years. These data confirm then the primary influence of the growing site, whose influence is superior to that of the growing season, in line with results from other zonation studies (Morlat and Bodin 2006;Tomasi et al 2011Tomasi et al , 2012.…”

The Power of the Terroir: The Case Study of Prosecco Wine

View full text Add to dashboard Cite

A zonation study, as noted in the previous chapters, presupposes a multi-disciplinary approach that is capable of identifying and interrelating among themselves soil characteristics, climate conditions, topographic features, biological elements (grape varieties and rootstocks) and human factors (historical and cultural) that are particular to an individual growing area (Deloire et al. 2005;Morlat 2001;Riou et al. 1995;Seguin 1986; Van Leewen et al. 2004).In this respect, zonation represents the most suitable tool to steer the viticulturalist to choices matching the site characteristics and to maximise quality, quantity and healthfulness of the crop.An in-depth understanding of the influences that these various natural factors exercise on the seasonal growth stages of the grapevine is likewise useful for individuating and realising, in the context of a specific growing area, site-distinctive qualities that are often difficult to achieve elsewhere.As previously noted regarding the research methodology, viticultural evaluations were carried out annually in each of subject vineyards selected in the study areas.To ensure scientific rigour, separate observations must be made concerning the data obtained from the two zonation projects, the eastern area of the DOCG Prosecco zone and the western area of DOCG Prosecco zone, since they were conducted in different years, each growing year marked by different weather conditions. Within the context of each study, however, homogeneity of vine training systems, age of the vineyards and rootstocks utilised, do allow both a comparison of the data obtained and extrapolations based on seasonal variations and on specific crop yields in the individual subzones. Vineyard YieldsThe potential yield of a vineyard is determined by many factors. Grape variety, vineyard layout, vine training system, soil fertility, water availability, weather and agronomic practices (Howell 2001): all impact yield and all of them must be monitored and managed in order to control the vineyard's crop level.

“…Hand pruning accounts for up to 75% of the yearly labor demand, and such high labor can be lowered through mechanization by 50 to 90%, according to the training system used and the extent of hand clean-up [2][3][4][5]. Moreover, mechanization may support the competitiveness of wines as it allows them to satisfy the wide market demand and can also be used to obtain high-quality wines in appropriate areas for modern mechanized and economically sustainable viticulture [6,7]. Indeed, the development of trellis systems suitable for mechanization has represented a further step to ensure the profitability of wineries in an increasingly competitive international market [8].…”

Effects of Mechanical Winter Pruning on Vine Performances and Management Costs in a Trebbiano Romagnolo Vineyard: A Five-Year Study

et al. 2022

Vineyard mechanical winter pruning has been spreading worldwide, and the physiological basis ascribable to it has been consolidated throughout the years. Despite labor savings and reduction of costs having been proven, the demonstration of its economic viability might be challenging. In this context, this work aims to evaluate the vine performances and the costs of different degrees of the mechanization of winter pruning over a five-year trial (2011–2015). In a vineyard of cv. Trebbiano Romagnolo (Vitis vinifera L.) located in northern Italy, three pruning treatments were laid out as follows: (a) manual pruning (MAN); (b) mechanical pre-pruning and simultaneous manual follow-up (MP + F); (c) mechanical pruning without a manual follow-up (MP). The results showed a strong increase in the node number of MP. Nevertheless, the yield compensation factors (i.e., the shoot fruitfulness and cluster weight) limited the increase in productivity. Soluble solids did not differ between the pruning treatments, while titratable acidity resulted slightly higher only on the MP berries. The MP treatment was the most economically convenient, with a vineyard surface of 1.5 hectares, while mechanical pruning with manual finishing resulted more advantageous, compared to manual pruning when the vineyard surface was greater than 2.9 hectares. The agronomic and economic results obtained in this five-year trial suggest that mechanical pruning may be profitably applied also on grapevine varieties characterized by low basal bud fruitfulness, such as Trebbiano Romagnolo.
