“…In comparison with other studies Walker et al, 2005;Matthews & Kriedemann, 2006;Holt et al, 2008), this paper explored a different range of berry weights with a generally larger average berry size and with an upper weight class higher than 2.5 g. It contributes to the study of the relationship between grape quality and berry size without the influence of other factors (cultural or environmental).…”

“…showed that, although total skin anthocyanins and seed tannins increased in relation to the size of berries, these components were more influenced by irrigation treatments than by berry size changes per se. Moreover, comparing wines from "small" and "large" berries, Walker et al (2005) came to the conclusion that berry size did not affect wine quality. However, Holt et al (2008) found that relations between berry size, must composition and wine quality were not straightforward.…”

“…Furthermore, these factors may also affect berry size and modify proportions of skin, flesh and seed in the grapevine berry. Differences in berry size may affect red wine quality by altering the skin:flesh ratio and modifying the amount of solutes extracted from skins during maceration Walker et al, 2005;Matthews & Kriedemann, 2006;Matthews & Nuzzo, 2007). In fact, if berry shape is considered a sphere, the berry surface:volume ratio decreases when berry size increases according to the ratio 3/radius (where surface area = 4πr 2 and volume = 4/3πr 3 ).…”

The effect of variation in berry size on berry composition was studied in irrigated Syrah/R99 grapevines, located in a temperate area of South Africa. Berries from 45 clusters, sampled from both sides of the canopy (east and west), were weighed to create four categories: 1. less or equal to 1.5 g; 2. between 1.51 g and 2.00 g; 3. between 2.01 g and 2.50 g; 4. more than 2.50 g. Berry physical characteristics were determined and total anthocyanins and seed flavonoids were analysed by spectrophotometry and anthocyanin profiles by HPLC. The ratio of skin weight:berry weight did not change with increasing berry size, but the ratio of seed weight:berry weight increased. For total anthocyanins, varying results were obtained if values were expressed in mg/berry, mg/g skin, mg/kg grape and mg/cm 2 skin. The quantity of total anthocyanins changed positively with increasing berry weight if expressed in mg/berry and remained almost similar if expressed in mg/cm 2 of skin. In contrast, total polyphenols decreased with berry weight if the values were expressed in mg/kg grape and in mg/g skin. Total anthocyanins expressed in mg/kg grape and in mg/g skin were correlated positively to the number of berries as well as to the total skin surface in one kilogram of grape. In this study, the largest berries seemed to have lower quality characteristics. In order to obtain better wine quality, it seems important to reduce berry weight and, in general, berry size variability of Syrah. The obtainment and continuity of a particular wine style may be affected by berry variability.

Impact of vine water status on berry mass and berry tissue development of Cabernet franc (Vitis vinifera L.), assessed at berry level

BACKGROUND Berry size is considered an important quality factor in red wine production. The objective of this work was to study the effect of vine water status on berry mass in field conditions, with a specific focus on berry tissue masses. RESULTS The study was carried out over 2 years in a plot located in Sicily (Italy). Two irrigation treatments were established. Dynamic evolution of berry mass and berry tissue masses at harvest were recorded. Berries produced under water deficit conditions were smaller and characterized by a higher skin‐to‐flesh ratio. However, this ratio did not change when berry mass varied independently from vine water status, showing coordinated growth of flesh and skin under these conditions. CONCLUSION The implications of berry size on skin‐to‐flesh ratios depend on the factor causing berry size differences. This finding might question the conclusions of most research trying to demonstrate that berry size is, or is not, an important parameter for quality. The factors impacting berry size are likely to differ according to the scale considered. This highlights the importance of investigating the causal effects of varying berry size, before possibly discussing the potential effects on fruit composition and, subsequently, wine quality. Berries produced by grapevines facing water deficit have a higher skin‐to‐flesh ratio. Hence, limited water conditions, represent a powerful tool to increase the concentration of major solutes involved in wine quality, which are located in berry skins rather than in berry flesh. © 2019 Society of Chemical Industry
