The name of the vineyard, that enjoys a beautiful location in the village of Castellinaldo, comes from “marasca”, a variety of cherries once quite commonly grown throughout in Roero vineyards. The key in producing this truly intense and elegant wine is with a green harvest, a thinning out process during the growing season that allows the remaining grapes to over-mature on the plant. This wine is produced only in the very best vintages.

Le conchiglie del Roero

The shells are the witness of the marine origins of Roero, a soil characterized by sandstones, rocks composed of sand and limestone. This soft soil, rich in minerals, enhances the aromatic characteristics of white wines and gives red wines great elegance and longevity.

Other wines


Our Classic Method Spumante was born were born in 1980 from Antonio Deltetto's passion for sparkling wines. From a careful vineyard selection, today we produce five expressions. In order to guarantee the highest quality level, each single step of production, from lees ageing to dégorgement is thoroughly followed and checked by our enologists, Antonio and Carlo Deltetto.

Artist's labels

The project grows out of the desire to embrace both art and culture. Each year we consider a particular sociocultural issue in depth.

Classic white wines

In Roero we find Arneis, the main grape variety, also considered between the most important ones of our region; our selection Daivej is dedicated to our ancestors. The Piedmontese sister of Vermentino from Liguria is called Favorita instead, much loved by La Bela Rusin, lover of King Vittorio Emanuele II of Savoy. To finish in sweetness, Bric du Liun: The low production, the overmaturing in the vineyard, the drying in small boxes in the open air and a bit of noble rot (botrytis) transform the grapes into a well concentrated, captivating nectar with an acidity that never allows it to lose its charm.

Classic red wines

Our family has always believed in native varieties from Piedmont such as Barbera and Nebbiolo. Our vineyards in Santo Stefano Roero, Castellinaldo and Canale were carefully selected after soil checks and exposures.


Our Barolo, vinified in our historical cellar in Canale since 1961, is dedicated to our grandfather Carlo Deltetto, founder of the company in 1953.

Langhe Suasì

These two wines, refreshing and a pleasure to drink, are made from a small selection of grapes harvested slightly in advance. The name "Suasi" comes from the Piemontese dialect, meaning "Chosen".


In collaboration with the historic Marolo distillery. Our white and aged Grappas were born from a careful selection of the best grapes from San Michele and Braja vineyards, in the heart of Roero. The white Grappa “PN-CH” comes from the steep hills of Alta Langa.

Our production has been certified organic since 2017 and our company has received an award in 2018 for its commitment to protecting the environment.
