Terroir

A multiplicity to know and valorize

A natural predisposition can be a limitation or an opportunity: the final result depends on its interpretation, on the people who work the land with devotion and competence to extract its essence. The area of Suvereto is rich of winemaking traditions which go back to the time of the Greeks and the Etruscans, who made wine in amphoras, and who carried out a prosperous metal trade here. But the land’s pedigree is not enough, especially when it is so nuanced: Petra is a collection of landscapes and microclimates, a series of substrates.

Terroir map

• Cantina

  Terroir	Geology	Soils
  Cantina	Calcareous turbidites (Cretaceous) and colluvial deposits	Soils of an orange-brown colour, medium texture and gravelly, well-drained. The pH is subalkaline and the calcium carbonate is medium or high.
  Officina	Clays and limestones and blue limestones (Cretaceous)	Thin soils, rich with clay flakes, very poor, low in carbonates.
  La Villa	Marine deposits (Pliocene)	Brown soils, deep, medium texture, calcareous and rich in sodium and magnesium, with an alkaline pH.
  Valdamone	Alluvial and colluvial deposits (Holocene)	Reddish-brown soils, deep, medium texture, not very gravelly and with moderate stagnant water deep down. Carbonates are low or non-existent.
  Riferraino	Ancient alluvial and colluvial deposits (Pliocene)	Orange-brown soils, deep, clayey-silty, gravelly. They are very low in bases (Calcium, Magnesium, Potassium) and rich in iron oxides. Sub-acid pH.

• Montebamboli

  Terroir	Geology	Soils
  Sant'Aurora	Fluvial conglomerates of Montebamboli (Miocene)	Ancient red soils, highly altered and poor, gravelly, medium texture and generally well-drained. They have a sub-acid pH, are rich in iron and low in bases, especially potassium. The “valley” variant indicates deeper and more fertile soils along watersheds, whilst “north” indicates less exposed slopes.
  Poggio	Clays and limestones and blue limestones (Cretaceous)	Brown soils, clayey and moderately stony, well-drained, subalkaline and slightly calcareous.
  Sant'Adele	Clays and limestones and blue limestones (Cretaceous), Marine deposits (Pliocene)	Very calcareous soils, with imperfect drainage, at a subalkaline pH, mild salinity and high sodium and magnesium content. The “vertisols” variant indicates soils with strong contraction and expansion of the clays, which cause.

• Riotorto

  Terroir	Geology	Soils
  Poggio Avvoltoio	Marine deposits (Pliocene)	Ochrey soils, clayey-silty, gravelly, with moderate stagnant water deep down. They are very calcareous and sometimes rich in sodium and magnesium.
  La Quercia	Clays and limestones and blue limestones (Cretaceous)	Brown soils, clayey, but well-structured, with moderate stagnant water deep down. They are subalkaline, and not very calcareous.
  San Frediano	Alluvial and colluvial deposits (Holocene)	Brown soils, deep, medium texture and well-structured, with moderate stagnant water deep down. They neutral or subalkaline, not calcareous.
