While walking through the rows of our vineyards you can admire the
fragments of this wonderful and shiny volcanic glass called obsidian,
which brings us back to the ancient times.
The new vineyards
The new company vineyards are in Villa Verde (Alta Marmilla) on the slopes
of Monte Arci, in a breath-taking landscape. The volcanic soil on which the
vines lie is rich in phosphorus, potassium and magnesium, which is perfect
for the production of quality wines. The area was affected by intermediate
lava phenomena which, from subsequent cooling, generated dark and not very
deep soils rich in obsidian. Obsidian, also known as “the black gold of the
ancient times”, is a volcanic stone that is abundantly present throughout
the territory and fortunately also in our vineyards. While walking through
the rows of our vineyards you can admire the fragments of this splendid and
shiny volcanic glass, which brings us back to the ancient times.
Our company philosophy aims at the enhancement of native varieties, and it is precisely for this reason that we have chosen to first plant the rootstock (1103 P), and then, the following year, to graft Cannonau, the most common grape variety of Sardinia, and Semidano grape variety, creating a fascinating and elegant vine which is nowadays very rare to find on the island. The planting density is 6000 plants per hectare and the training methods adopted are bilateral spurred cordon for Cannonau and guyot for Semidano. In both cases we have chosen to set the fruiting heads at a very low height from the ground (50 cm c.a).

With this setting, the plant consumes much less energy in times of water stress.
The consequences are that the supply of water and nutrients originated by the
clusters and the leaves is conducted over the whole vineyard more easily
and with less expenditure of energy. This choice enables us to have a
reduced and not very expanded crown which is very similar to the gobelet
(the italian alberello), a training system designed to adapt the vine
to difficult environmental conditions, obviously offering much lower
quantitative yields but significantly enhancing the qualities of the
vine. The vineyards are completely managed following the principles
of the organic agriculture, since we have never considered the use
of chemical fertilizers, herbicides and synthetic products for
phytosanitary defense. For the management of soil fertility, we use the
agronomic practice of green manure with a mix of legumes and grasses
and sometimes we make specific organic fertilizations. Only if a soil
is fertile and vital (rich in microflora and microfauna) a plant will
grow well and bear excellent fruits.
Because of that, our task as farmers is also to better manage our land and, more generally, the ecosystem in order to ensure better living conditions for future generations.
