Influenza di alcuni aspetti ambientali sul contenuto di stilbeni nel vino nell’area della DOC “Sangiovese di Romagna” (Italia)

The chemical composition and the sensory characteristics of wine result from dynamic interactions between several factors including grape variety, soil, viticultural techniques, climate conditions, yeasts metabolism, oenological approaches. Recently, Grigg et al.

Temperature has a decisive influence on the growth and development of plants (Carbonneau et al., 1992). In particular, in the case of the vine, the temperature is an omnipresent variable in the climatic indices (Huglin, 1986). For reasons of convenience, these indices use the temperature of the air measured under shelter in a meteorological station, making the implicit hypothesis of a concordance between this temperature and that of the sites of perception of the thermal stimulus by the plant. However, development may be more dependent on soil temperature than air temperature (Kliewer, 1975). Morlat (1989) thus verified that the variability in the precocity of the vine, positively correlated with the quality of the harvest and of the wine in the Loire Valley, was mainly explained by differences in temperature of the root zones.

En el Norte de la Isla de La Palma (Islas Canarias), se cultivan un conjunto de varietales constituidos principalmente por Negramoll, Listán blanco, Prieto, Albillo y Muñeco.

Wine aroma quality is a complex interplay of factors like terroir, vinification techniques, that modulate aroma compound composition.

Hillside vineyards have a great potential to produce world class wines. The unique microclimate lead to the production of rich, flavory wines.
