The weather in 2021 is difficult to define within a precise category. There were alternating conditions which, in the end, found an almost surprising balance and which favoured a perfect phenolic maturation of the grapes, protecting the acidity.
The fall of 2020 through the winter of 2021 saw little rainfall recorded, only 220 mm in the period from October 1, 2020, to March 31, 2021. Winter was characterized by minimum temperatures around zero in the months of December and January to then undergo an above-average increase in temperatures in February, which was then interrupted by the cold at the beginning of March.
Starting on March 20, we saw a progressive rise with temperatures tending to be above average at the start of spring, which favoured a more accelerated vegetative regrowth and initial growth. These conditions were the reason for the measurable damage incurred on the night between April 7 th and 8th, 2021 when, in full vegetative development, a thermal inversion phenomenon brought the nighttime minimum temperatures down to -9°C, which inevitably damaged the new buds, creating a reduction in production of about 30%.
The month of April started ideally with average seasonal temperatures and a good supply of water of about 50 mm which favoured an optimal recovery of the vines from the stress of the frost. The vines started to find a balance based on their smaller yield. The month of May, with rainfall at only 40 mm and mild temperatures, saw optimal health in the vines, without disease and with a very gradual growth pattern. June and July were two dry months, with very warm temperatures but never scorching hot, with only three days above 35°C, always compensated by ideal temperature ranges, allowing the plant to breathe. The beginning of August saw the arrival of a heatwave which, fortunately, lasted only from August 12 to 16 and did not damage the fruit.
The vines, despite the long dry period and some intense heat, maintained a surprising balance as well as a canopy that was in full photosynthetic activity, green and receptive, bringing the grapes to a regular veraison. Even in these extreme conditions, this can be explained by two factors: - The frost in April left the plant with a reduced number of grapes and this allowed it to have sufficient energy to carry on with the maturation, avoiding any stops. - The significant regular temperature ranges over the season favoured an ideal continuity allowing the vines to breathe.
At the end of August, the magical period for the 2021 vintage arrived. The highs were on average for that period, 30 mm of rain gave the necessary quantity of water for the vines to completely ripen recreating the right balance between skin and liquid, the temperature ranges were consistently between 13° and 15° until the harvest, in keeping with great vintages which always benefit from a great September. The variation in temperature between day and night, which permitted us to achieve an optimal result on the Fregoni Index (443), is the determining factor in understanding a vintage which presents with typical vibrant wines of fresh and, at the same time, full bodied vintages, typical in warmer years.
The harvest, carried out in a period without rainfall, was regular and we had the opportunity to decide the best harvest date for each vineyard, waiting for the right balance between technological maturation and phenolic maturation.
Once again, the 2021 vintage has taught us and confirmed to us that weather conditions must be interpreted and that September is becoming increasingly crucial in affecting, favourably or unfavourably, the work of an entire year.
