Terroir

• The Colli Tortonesi production zone consists predominantly of sedimentary soils belonging to the stratigraphic succession of the Tertiary Basin of Piedmont.
• The Tertiary Basin is defined as the complex of sediments forming the hill ranges of the south-eastern sector of Piedmont, with a predominantly SW–NE aspect.
• The hill ranges of the Colli Tortonesi area present slopes of between 15° and 30°, as described in the geological documentation.
• The Colli Tortonesi production zone encompasses the viticultural hill belt of thirty communes situated in the south-eastern part of Piedmont, in the province of Alessandria.

• Timorasso is a grape variety with ancient roots that has now been revived; it is the emblem of Colli Tortonesi, and the quality of its wines has earned it numerous awards and top placings in wine competitions.
• The Colli Tortonesi appellation was established by Presidential Decree of 9 October 1973, published in Official Gazette no. 68 of 13 March 1974. (via Wikipedia · CC BY-SA 4.0)

• Colli Tortonesi wines display a pronounced salinity, and the clay-marl soils transfer mineral salts to the grapes and consequently to the wine, including lithium.
• The wines produced show a strong aptitude for ageing, a characteristic that extends to the white wines of the Colli Tortonesi appellation as well.
