The first two months of the year has registered cold temperatures, below the seasonal average, while, on the contrary, March and April has been exceptionally warm, with peak temperatures up to 25-28 C° degrees, which brought forth a bud-burst before time. This can be considered a dangerous condition and it actually had immediate effects with the late freezes of April 9th , which damaged the buds. A very changeable weather during the month of May, both for rainfalls level and temperatures; this condition remains basically unchanged even for the month of June and makes more difficult maintaining the phytosanitary protection in the vineyards.
In the end of June the weather has cleared up, with more stable conditions, summer temperatures and scarce rainfalls.
By the end of July the vines start suffering from the effects of scarce rainfalls; only a few providential but too scarce rainfalls were not enough to ease the draught and, it has been therefore necessary carrying out watering operations on a few estates.
August was characterized by warm temperatures above the seasonal average (beyond 35 C° degrees) and absolute lack of rainfalls since July 20th.
After an early harvesting, due to the heavy draught and high temperatures, has been eventually followed by abundant rainfalls and thunderstorms starting from September 12th.

Thermal Summation: this value, expressed in Celsius degrees, shows the sum of differences between average dayly temperature and the so called “vine’s zero of vegetation”, which is equivalent to 12° for the vines. The values reported into the column “Thermal Summation”, show the thermal sum from the beginning of the year up to the relevant week of that same year; these values show the performance of seasonal temperatures.
WHAT: This graphic shows the data related to rainfalls, daytime and nighttime temperatures registered for every single vintage within the production area Montello and Asolo hills. (official statistics data provided by “C.e.c.a.t Institute”)
HOW: These data have been registered in the period between the third April’s week and the first September’s week, which is the most active and intense period of physiological activity for the vines, starting from the initial growth until the final maturation of the fruits right before harvesting, which usually takes place in the month of September and/or October, depending from the grape variety.
