At the beginning of may in Italy and some traditional warm European regions the temperature dropped to -2 °C. In normal conditions, this would mean the destruction of the grape harvest. However, 300 torches, placed in the territory of 1 hectare, is able to heat the surrounding air by at least three degrees – and in the vast territories blazed lights.
Unfortunately, this did not save the situation everywhere: for grapes is the critical temperature -1 °C, and in some regions may frosts showed record values at the level of -6 to -9 °C. Winemakers estimate losses in the millions of euros.
