The territory

Our wines are grown in the Friuli Isonzo DOC zone. The appellation owes its name to the river that flows through the eastern portion of Friuli Venezia Giulia: the Isonzo. The area covers a territory that goes from the Collio hills and the Karst down to the Adriatic Sea.
Friuli Venezia Giulia stretches from the Alps to the coast of the Adriatic Sea and features widely varied landscapes: the mountains, which are not too high and have sharp, jagged peaks, while the hills slope gently down to the plains and to the coast.
The region boasts a unique climate due to the convergence of two winds: the Bora, which is cold and fierce, and the Sirocco, which blows across the sea picking up warmth and moisture. In this climate the grapes ripen slowly and evenly preserving balance, and a nice concentration of aromas and rich flavours. The latitude at which our grapes grow is the same as that of Burgundy and the Willamette Valley in Oregon.

SOIL TYPEMixed gravels and decalcified limestone

ALTITUDE35/50 m. a.s.l.


The area features clayey soils and limestone pebbles. This type of soil allows for adequate water retention ad contributes minerals and microelements, such as aluminium and iron that grant the wine the characteristics and flavours typical of its terroir. Our vineyards grow on both types of soils, which is why we can achieve the right balance between body and acidity, and produce wines that reveal the typical mineral aspect of Friuli Isonzo DOC wines.

From the soil to the wine: Ferretti

When Francesco Luisa planted his vineyards of Merlot and Cabernet back in 1927, terms such as resveratrol and polyophenole were virtually unknown to him. Nevertheless, the Merlot and Cabernet grapes that grew on the red soils located in the triangle of land between Farra d’Isonzo, Medea, and Cormòns, were indeed special. And that something special is the so called “ferretti” which also gives our selection its name.
The ferretto soil originates when the gravely substrate mingles with the soil and in turn causes the de-calcification of the surface forming the red soil, which owes its colour to the free iron hydrates. The grapes that grow on these particular soils give great red wines that age well and white wines that have a firm structure and a long cellar life.

The Vineyards

For the top floor of the building that houses our winery and cellars we envisioned a panoramic lounge from which enjoy the view of all our vineyards. Indeed, from here the eye is drawn across the vineyards and the horizon beyond, crowned by the Collio hills, the Karst highlands, and the hill overlooking the village of Medea.

Our vineyards lie part near Cormòns, which is ideal for growing grapes that give refreshing, fruit-driven white wines, and part in the area between the villages of Mariano and Corona, which are more suitable for red wines.

VINE TRAINING SYSTEMSingle arched-cane Guyot

DENSITY5,000/6,000 vines per hectare

YIELDS80/100 quintals per hectare

VINEYARD TECHNIQUEnatural grass cover crop

IRRIGATIONDefoliation, cluster thinning

We strongly believe that the quality of a wine originates in the vineyard. We opt for high vine density, 5,000/6,000 vines per hectare, on grassed-over rows. In summer we carefully thin the clusters to achieve the highest quality possible. We have implemented a drip irrigation system, being convinced that it is the only method that fully respects the balance of the plant, and we carry out leaf removal by hand.
The yields are kept low, reaching a maximum of one to one and a half kilograms of grapes per plant. Following this method we obtain healthy grapes with a high sugar concentration, which is ideal to provide structure and longevity to the wine without losing its freshness.
For our lighter wines we choose to harvest the grapes early and leave some rows of grapes for late harvest. The grapes of each vineyard are vinified separately, and only at the end of the process do we assemble the wine to maintain the best balance between body and acidity.

Good vineyard management makes it possible to reduce the quantity of sulphites added. Our wines contain less than 80 mg/l, which is less than that provided by law for organic wines, where the quantity allowed is up to 100 mg/l for red wines and 150 mg/l for white wines.
