Abstract
The importance of viticultureis widely known for its many uses, but mainly because of
winemaking, which is one of the most profitable industries of the world. The purpose of this
work was to record the phenological stages and to determine the quality characteristics of the
four wine grape varieties 'Syrah', 'Merlot', 'Mataro' and 'Xynisteri'. The grapes of the four
varieties were harvested from the village of Pachna in the province of Limassol. The 'Syrah'
variety was harvested on 02/08, 'Merlot' on 03/08, 'Mataro' on 11/08 and 'Xynisteri' on 05/09.
Grapes from the four varieties were harvested at the stage of technological maturation in order to
determine the qualitative characteristics. In addition, the phenological stages of the grapes, were
monitored every fifteen days. The measurements taken during the determination of the
qualitative characteristics of the varieties were the weight of the crimp, the weight of the berries,
the total weight of the grape, the number of berries of each grape, the weight of thousands of
berries, the total soluble solids (TSS), total acidity, pH, the coefficient of maturation and color
markers (intensity and hue).
Results showed that ‘Xynisteri’ has the greatest grape weight compared to the other varieties.
The levels of the TSS in the four varieties differ, since there is a 6% difference between the
'Syrah' variety with the highest TSS content compared to the lowest content of ‘Xynisteri’. The
pH in the four varieties as expected was close to 3 and the results on total acidity showed
differences among the examined cultivars. Also, regarding the phenological stages we conclude
that the earliest variety is ‘Syrah’, while the latest is ‘Xynisteri’. Comparing the results of this
work with other studies, we come that the role of 'terroir' is very important in the composition
and qualitative attributes of each variety.
