Grape

Fiano

Fiano is a white Vitis vinifera grape most closely associated with the hills around Avellino in Campania. It makes dry wines that can combine a substantial middle palate with freshness, and whose aromas often develop with bottle age. Its usefulness extends from young, fruit-scented whites to wines in which floral, nutty, and honeyed impressions unfold over time.

Fiano di Avellino identifies its protected inland wine. The grape also grows elsewhere, including other parts of Campania.

Hills, climate, and the vine

The Avellino hills experience cold winters, spring frost, and marked summer differences between daytime and nighttime temperatures. Their inland setting helps explain how a southern Italian white can retain freshness through ripening. Clay-rich soils in parts of the zone also hold water through the dry summer, although drainage, soil depth, and slope vary between vineyards.

Fiano is vigorous. Vivai Cooperativi Rauscedo recommends comparatively dry, less fertile hillsides and suitable pruning to manage its growth. Fertile sites can demand more work on the canopy. The grape has fairly substantial skins, and its bunches vary in compactness. Wet spring weather can produce uneven berry development, while powdery mildew deserves particular attention.

Harvest timing varies with site and season. Rauscedo's clonal descriptions also differ in acidity and suitability for longer maturation, reflecting the variation in plant material available to growers.

Aroma and development

Young Fiano can suggest flowers and fresh fruit. Hazelnut is a familiar association, but studies assembled by the University of Naples and Regione Campania show a broader and changing aromatic profile. In their bottle-ageing observations, apple and banana impressions became less frequently cited, while several floral, nutty, and honeyed impressions became more prominent. Those results describe the wines studied, without establishing a timetable for every bottle.1. Regione Campania and Università degli Studi di Napoli Federico II, Colori, odori ed enologia del Fiano, edited by Luigi Moio, 2012, chapter 4, especially pp. 97–112.

Aroma depends partly on compounds already present in grapes and partly on compounds formed or released during fermentation and maturation. The same research programme examined both free aroma compounds and bound precursors that can yield odorants later. This provides a useful explanation for Fiano's ability to change after its initial fruit aromas subside. Nutty or honeyed aroma can occur in a dry wine.

Fiano di Avellino

The production specification published by the Irpinia consortium requires at least 85% Fiano, with a limited balance of Greco, Coda di Volpe, and Trebbiano Toscano. Its area includes Lapio, Montefredane, Summonte, and other communes around Avellino.2.
