Safe up to 87% of harvest during the frost period using a sustainable solution

Did you know that 71% of the world's grape production is used for wine? According to the Food and Agriculture Organization (FAO), 75,866 square kilometers of the world is dedicated to grapes and the total worldwide wine production comes to 31 billion liters. 

Late spring frost is one of the greatest challenges vine growers are facing. Non-heated grapes can suffer considerable inflorescence damages (up to 50%), whilst heated grapes will have dramatically improved protection of harvest loss or damage and reduce the losses to approximately 13-20%. 

Worldwide, the grape and wine industry rely on three main alternatives for frost protection: frost fans, sprinklers, and candles.

Short Facts about vineyards:

The largest producers of wine in the world vary from year to year, the current leaders being Spain, Italy, France, South Africa, New Zealand, Argentina, Chile and Australia.

Wine grapes mostly grow between the 30th and the 50th degree of latitude, in both the Northern and Southern hemispheres. Grapes will sometimes grow beyond this range; thus, a small number of wines are made in some rather unexpected places.

With environmentally friendly, electric protection solutions for vineyards, you can choose the vinery’s corresponding power necessary per meter, according to its geographical position and temperature fluctuations.
