Gutturnio

Styles

Principal grape varieties

Terroir

• The climate of the production zone is temperate sub-continental, with a mean annual temperature of between 10 and 14.5°C and one to three summer months above 20°C.
• Annual rainfall ranges from a minimum of 700–800 mm in the foothill belt to approximately 1,000–1,100 mm at the upper limit of 500–600 m elevation, following a sub-littoral Apennine rainfall regime.
• In the hill belt between 200 and 500 m elevation the climate shows smaller daily and annual temperature swings than the plain, making it particularly well suited to quality viticulture.
• The Winkler bioclimatic index in the hill belt ranges between 1,500 and 1,800°C, with the highest values on south-facing slopes and at lower elevations, while the Huglin index falls between 1,800° and 2,000°C.
• The soils of the Val Tidone have a high clay content with a fine texture and a greater richness of potassium compared with the soils of the Val d'Arda and the other central valleys of the province.
• In the Val Nure and Val Trebbia most soils have a silt-loam texture, with a portion of clay-textured soils and another of balanced medium-textured loam.

• Piacenza's grape growers have traditionally trained the vine low using carasse stakes — the vinae characatae described by Columella — following the principle that it is the stake that makes the grape.
• The most celebrated artefact associated with the wine's name is the silver jug known as the gutturnium, found in the Po at Croce S. Spirito in 1878 and today preserved in the Capitoline Museums in Rome.

• In the warmer zones Gutturnio is presented as Superiore or Riserva thanks to a higher alcohol content and a greater polyphenolic fraction in the grapes.
