RARE GRAPE VARIETAL RESOURCE

History: The cultivation of Alionza dates back several centuries and has been traditionally concentrated in the Emilia-Romagna region, especially in the provinces of Bologna and Modena since at least the early 14th century, when it was documented in Italian agricultural writer Pietro de' Crescenzi's Ruralia commoda treatise.

During the 19th century, the grape variety was widespread in the Emilian provinces, especially in the Bologna area, where it was vinified alongside Trebbiano and Malvasia to produce light, fragrant wines. With the progressive mechanization and standardization of production, Alionza was almost abandoned, surviving only in small plots and in ampelographic collections until its recent rediscovery as part of projects to enhance the value of the minor grape varieties of Emilia-Romagna.

Today, Alionza is considered an endangered grape variety, with fewer than 50 hectares still under cultivation across Italy. Despite its rarity, this grape remains a valuable part of Italy’s viticultural heritage, representing a link to the region’s ancient winemaking traditions. There is a growing interest among small producers and enthusiasts to revive the Alionza grape as part of Italy’s movement to rediscover and preserve native varietals. Recently local consortia have initiated genetic studies and microvinifications to better understand its potential, discovering a variety with an interesting acid balance and good aromatics, ideal for fresh white or Charmat method sparkling wines.

Officially registered in the National Catalogue of Vine Varieties since 1987, the grape has a reputation for being a reliable crop, producing consistent yields and having strong resistance to several viticultural hazards such as botrytis bunch rot, late spring frost and powdery mildew.

The vine thrives in well-exposed soils and warm climates, preferring sunny hillsides where it can reach full ripeness. When vinified, Alionza produces a straw-yellow wine that is harmonious, balanced, and pleasantly full-bodied. It’s a wine with good preservability, offering subtle floral and fruity aromas with a round, persistent finish — an excellent example of the hidden treasures of Italian viticulture.

In the early 21st century, DNA analysis has suggested that there may be a close genetic relationship between Alionza and the white Tuscan wine grape Trebbiano, known as Ugni Blanc in France.

Tasting notes: Alionza wines are straw yellow in color with greenish highlights, clear and bright. On the nose, they offer fine and discreet aromas of wildflowers, green apple, pear, and citrus, accompanied by light mineral nuances .

On the palate, they are fresh, harmonious, and medium-bodied, with balanced acidity and a dry, clean finish. The sparkling versions express fragrance and immediacy, while the still versions display a broader structure and a pleasant savory sensation. (https://www.quattrocalici.it/)

Food pairings: Alionza pairs easily with traditional Emilian dishes, from cured meats to stuffed pasta, freshwater fish, and vegetable dishes. (https://www.quattrocalici.it/)

Production areas: Today it is mostly used as a minor blending grapes in some of the Indicazione Geografica Tipica (IGT) and Denominazione di Origine Controllata (DOC) wines of the region; Colli Bolognesi DOC
