After a mild and dry autumn, the winter of 2012 in Chianti Classico was characterized by cold temperatures and normal rainfall, above all in the months of January and February. During the first half of February, in particular, temperatures dropped and snow fell without, however, damaging the vines. Spring began with rather cool and dry weather, causing a slight delay in bud burst and flowering compared to previous years. The months of April and May were marked by ample precipitation, a fundamental factor in enabling the vines to confront the lengthy rainless period which began in June and lasted all the way to the end of August, conditioning the development of vines both in terms of the growth of the canopy and the size and weight of the berries. The rain which fell during the very last days of August brought the vineyard back into balance, assisting the different grape varieties to proceed with regularity towards fully ripening, while the months of September and October, both mild in their temperatures and with normal rainfall, enabled the grapes to ripen properly both in terms of the accumulation of sugars and the physiological maturity of the skins. The harvesting of the grapes was concentrated in the period between September 20th and early October.
