The Moraine Amphiteatre of Ivrea
Seen in greater detail, the Moraine Amphitheatre of Ivrea consists of a low relief in the shape of a high plateau, particularly on the southern side: Erbaluce is grown between 200 and over 500 metres above sea level.
The vineyards are situated in loose, acidic soils, with a very recent matrix and good stone structure, made up of sand, pebbles, stones and a small amount of silt and clay.
These are poor soils that provide little stimulus for plant growth. However, as the roots of the vines penetrate deeper, they find richer soil in the underlying strata, sometimes with a fair percentage of clay.
The Erbaluce vineyard
The Erbaluce vineyard is traditionally cultivated in the form of a pergola.
The “Pergola Canavesana” or “Pergola di Caluso” has a flat top and a height of between 180 and 200 cm. The average vine layout is four metres by two metres, resulting in a plant density of 1300 vines per hectare. Traditional pruning is known as “three-pointed”, with three canes, each bearing ten buds at the end. There is a spur, a fruit cane, a two-year-old fruit cane and a third fruit cane on a three-year-old branch. This system means that all the main operations in the vineyard, pruning, green pruning and harvesting, must be done by hand.
