“…Our aim was to guide producers in possible management techniques of the vineyards, to improve yield, grape and wine composition, and wine quality. In line with recent studies (Bramley 2005, Bramley et al 2011a, Lamb et al 2004, we have used remote sensing to evaluate possibilities of zonal management.…”

“…Variation in vineyard vigour and soil properties can be associated with spatial variability in grape composition with implications for wine composition, style and quality. A considerable body of research has reported patterns of spatial variation in vineyard attributes related to soil variability, such as vine vigour, yield, fruit ripeness, and wine colour and phenolic composition (Johnson et al 2001, Lamb and Bramley 2002, Johnson 2003, Bramley and Hamilton 2004, Bramley 2005, Bramley et al 2011a, Trought and Bramley 2011.…”

Background and Aims: Spatial and temporal variability of vine vigour within a vineyard block, associated with variation in soil physical and chemical properties, affects yield, and fruit and wine composition. The objectives of this study were to measure this variability and possible causes for a commercially important vineyard area in Hawke's Bay, New Zealand. Methods and Results: Three vigour classes, and measurement of vine nutrient and water status, vegetative growth and canopy attributes, yield, fruit ripening profiles, and grape and wine composition over two seasons characterised vigour variability of Cabernet Sauvignon vines growing on the 'Gimblett Gravels' area of Hawke's Bay, New Zealand. Vine nutrition and growth differed between vigour zones with extreme nitrogen deficiencies recorded. Vigour did not affect vine phenology. Normalised Difference Vegetative Index measurements quantified vigour differences. High vigour vines showed a higher yield, but fruit ripeness, wine anthocyanins and phenolics, and some sensory attributes were significantly reduced. Excessively leafy canopies associated with high vigour were responsible for these effects. Conclusions: Soil-induced vine nutrient deficiencies, rather than differences in vine water status, influenced vine vigour. Measures of vegetative growth and canopy attributes suggested negative implications of excessive shading with high vine vigour. Significance of the Study: This study showed the relative significance of nutrition in affecting vine vigour on sandy gravel soils. A good correlation between remotely sensed vigour zones, and grape and wine composition permit on-ground zonal management to minimise the negative effects of spatial variability.

“…However, variability within vineyards makes this difficult to achieve (Bramley et al, 2011), so some researchers have proposed the manufacture of wines of different-quality (Noguerol-Pato et al, 2012;Figueiredo-Gonzalez et al, 2013). Wine elaboration guarantees quality and prevents adulteration, and the demands of the global wine market for wines with particular and distinctive characteristics must be met (López de Lerma et al, 2013).…”

The differences among young wines from berries at 3 heights (fruit-zone 1 (FZ1): 140-200 cm above the ground; FZ2: 80-140 cm; FZ3: 20-80 cm) on Vitis vinifera L.cv Merlot and Chardonnay were assessed to evaluate the influence of berry-heights on the final wine quality. Stir bar sorptive extraction coupled with gas chromatography-mass spectrometry (SBSE-GC/MS) was used to analyse the characteristics of wine aromas. The results revealed that berry-heights exert significant influence on ethyl octanoate, isoamyl acetate, ethyl hexanoate, and ethyl butanoate in various-FZ Merlot wines and beta-damascenone in the Chardonnay -FZ wines. As a result, FZ1 wines of Merlot are more aromatic than the other FZ wines and had the highest floral and fruity series intensity. For the Chardonnay wines, fruity and sweet series were highly intense in the FZ1 wines. The PCA results demonstrated a high degree of differences in the aroma of various-FZ wines of the 2 grape cultivars, especially the Merlot variety, which indicates a need to separate the berries from the different-FZs. These results suggest that wineries should consider the possibility of separating berries from different-heights to produce wines of distinctive quality. Furthermore, this knowledge about the volatile composition of young wines offers a means of evaluating the aroma potential of wines from berries taking into account their position along the vines.Keywords: berries of different-heights; wine aromatic compounds; Principal Component Analysis (PCA); odour activity values (DAVs).Practical Application: There are significant differences in the aromas of wines produced from berries at various heights on vines, indicating that wineries should consider separating berries from different-heights to produce wines of different quality.

“…Some of these sources of variation remain stable along time, as observed by Bramley & Hamilton (2004). The study of these patterns can lead wineries to a better understanding of the different qualities of batches, in order to plan different winemaking procedures and get a better profit from the grapes (Proffit et al, 2006;Bramley et al, 2011). Furthermore, this information allows targeted crop management in terms of inputs (irrigation, fertilizers, spraying) and cultural practices (pruning, shoot and grape thinning, canopy management); with 2 tion of remote sensors, allowing for calculating new indexes based in other narrow wavelengths capable to detect chlorosis, water stress or nutrition deficiencies in grapevine.…”

<p>The prediction of grape composition is becoming more important due to the need of reducing the current levels of alcohol and pH of the wines, a problem that is exacerbated by climate change. This work presents a 3-year study of the spatial variability of grape composition in a rainfed Tempranillo vineyard located in Rioja (Spain). It is based on the acquisition of multispectral imagery at <em>véraison</em> (start of the ripening process); and zoning based on NDVI, to assess its performance for zonal management. The results reveal a high spatial variability within the plot, with a stable pattern over the years, even with very different climate conditions. NDVI was a good predictor of vegetative growth variables. However, the prediction of grape composition was more complex. Unexpectedly, anthocyanins were found to be higher in the highest vigor zone, which is probably related to the effects of climate change. This unexpected relationship is particularly discussed in the article.</p>
