The soil on volcanoes is sandy and its chemical composition varies from place to place. Everything depends from the geological history of the volcano’s eruptions.
The soil is formed by the disintegration of one or several types of lava of different ages and eruptive materials like lava, rocks and ash.
This type of soil, do not hold water. Therefore, plants have to work hard to establish a root-system that tap into the heart of the volcano, soaking up the enormous power and intensity and delivering to your glass.
This is why there are many minerals like iron, phosphorus, magnesium, copper and silicon. Vineyards are also particular rich of lapillus, little globular rocks coming straight away from the volcano’s pit during the eruptions of the past.
In general, wines share bright acidity, saline character and lifted flavour profile. The wines from these unique soils are made from indigenous varieties and show exceptionally-pure varietal definition.
Therefore, every wine-yard gives a distinguished taste to the wine even within hundred meters of distance.
Finally, the sand of volcanic soil means that vines are immune to phylloxera; therefore the age of the vines can be in many cases more than 100 years old.
