Over time, wine production, vineyard surface area and wine consumption have been drastically reduced, leading growers and winemakers to search for improvements in the sector. Among these techniques we have clonal selection, that allows the selection of the best genotypes in order to obtain higher quality wines. In the Valencian wine culture, the Bobal variety is considered the star of the Utiel-Requena Denomination of Origin. This variety stands out for its high levels of polyphenols and acidity, its high productivity and resistance to drought, which gives rise to red and rosé wines. However, its main problem lies in the compactness of its berries, which directly affects the health status of the grapes. In the present work, a selection of 8 different clones of the Bobal variety was carried out, which were planted in four different plots. In order to select the best clone, analyses were carried out to study its polyphenolic concentration, among others. The results show that, although all clones can produce wine, clone 11.5 stands out from the rest.
