The 2017 vintage was quite hot but in many respects substantially different from previous vintages, such as 2003 or 2012. Although with a spring and summer season characterized by temperatures often above the norm, the vegetative conditions of the plants and the results in organoleptic terms of the grapes and musts to which they originate in the Bolgheri area are highly respectable. Autumn and the first part of winter were characterized by cold temperatures, conditioned by northerly winds and medium rainfall. Conditions that allowed vegetative growth to stop, contained the main vine parasites and kept the water reserves of the land in balance. The bizarre climate at the beginning of spring, with temperatures that were already well above average at the end of March, affected the good progress of flowering but also of fruit set, giving rise to smaller bunches and fewer grapes. That is, the consequence of an average production reduction of 18-20%. If this led to a lower production, otherwise it further favored the quality of the grapes and created a more sustainable condition for the vines which brought their load of grapes to maturity regularly, albeit with a very hot summer. The summer continued with sunny days, warm temperatures and no rain until the end of July. In mid-August, with the beginning of the phenolic ripening of the grapes, the arrival of a disturbance of Atlantic origin which brought rain for 2 or 3 days and caused the temperatures to drop significantly, created the ideal conditions to favor the completion of the phenolic ripening of the grapes, rather than the technical one. The vegetative conditions of the vines and above all the vital functions have never suffered interruptions or stress conditions and this has allowed the plants to continue to regularly carry out their photosynthetic capacity to the benefit of the phenolic action which is decisive in the ripening of the grapes. The rains that fell at the most crucial moment of this action also allowed the grapes to increase in weight and size thanks to cellular distension, diluting the concentration of sugars (glucose and fructose) while maintaining the good supply of polyphenols in perfect balance. 2 The alternation of night and day temperatures that occurred from mid-August to the end of September favored the development of primary and secondary aromas, and equally determined the increase in acidity which was truly essential to give freshness and elegance to the musts.
