Ortrugo dei Colli Piacentini

Styles

Principal grape varieties

Terroir

• Temperate subcontinental climate with a mean annual temperature between 10 and 14.5°C; up to 3 summer months exceeding 20°C.
• Calcareo soils low in potassium promote high acidity in the grapes, making them ideal for fresh, age-worthy sparkling wines.
• Strongly differentiated microclimate conditions over short distances, shaped by parallel valleys, varying aspects, and sheltered orographic depressions.
• Active ventilation from breezes discourages humidity and frost; south-facing hillside sites record winters 1–2°C milder than the plain.
• The considerable gradients of the vineyards promote water percolation and soil desiccation at ripening, concentrating sugars in the berries.

• From the 1970s onward, Ortrugo evolved from a blending grape to a variety vinified as a single varietal, becoming the most widely produced white wine in the Piacentino. (via Wikipedia · CC BY-SA 4.0)
• Research into viticultural suitability conducted by the Università del Sacro Cuore di Piacenza (1988–1991) and by the Consorzio in collaboration with the Ministry (1993–1995).

• A delicate and characteristic bouquet, the hallmark of Ortrugo vinified as a single varietal since the 1970s. (via Wikipedia · CC BY-SA 4.0)

• Calcareo soils low in potassium encourage acidity in the grapes, and are considered ideal for fresh, age-worthy sparkling wines.
