THE ANCIENT ROMANS AND THEIR DESCEDENTS IN ITALY AND SPAIN HAVE TRADITIONALLY GROWN GRAPES ON PERGOLAS.

THE POST IS MORE THAN 1.6 M HEIGHT, AND IT ENDS IN A FLAT STRUCTURE, HORIZONTAL TO THE GROUND, WITH WIRES IN ORDER TO SUPPORT THE BRANCHES. THE BUNCHES WILL GROW BELOW THE WIRES AND THE LEAVES, WITH GOOD AERATION.

IT IS AN EXPENSIVE SYSTEM, BOTH TO ESTABLISH AND TO MAINTAIN. PERGOLAS ARE USED IN REGIONS WITH HIGH HUMIDITY CONDITIONS, SUCH AS GALICIA. IT LOWERS THE RISK OF FROST AND AVOIDS SOME DISEASES, SUCH AS ROT.
