In 1904, in the council chamber of the municipality of Serralunga, in the presence of Notary Giacomo Oddero and the young witness Alfredo Prunotto, the Cantina Sociale "Ai Vini delle Langhe" was founded. Among those participating in the founding act were figures who had left their mark on the history of Alba and the municipalities of the Langhe, as well as many small local producers.
The first harvest was in 1905. Difficult years followed, characterized by a general economic uncertainty, exacerbated by the First World War. In 1922, when the renewal of the Cooperative Winery expired, many members decided to stop contributing their grapes. The year, while exceptional, was not a bumper one. The winery began to experience serious financial problems and was placed into liquidation.
During this time, the young Alfredo Prunotto met and married Luigina, with whom he decided to take over the "Ai Vini delle Langhe" winery, naming it after himself. Thanks to the couple's passion, the winery quickly became famous and began exporting Barolo and Barbaresco worldwide: first to South America and then to the United States, whose markets were opening up in those years. Prunotto was one of the few wineries to believe in this economic prospect.
In 1956, Alfredo Prunotto decided to retire from business, handing the company over to his friend, the winemaker Beppe Colla, assisted by Carlo Filiberti and later by his brother Tino Colla.
In 1961, Prunotto began to identify particularly valuable production areas for the separate vinification of Cru wines, such as Barolo Bussia and Barbera d'Alba Pian Romualdo.
In 1972, Ugo della Piana, an architect originally from the Langhe, designed the new winery, which was built near Alba, where the company's headquarters are still located today.
In 1989, the Antinori family began its collaboration with the Prunotto company, initially handling distribution and then, in 1994, with the retirement of the Colla brothers, also directly taking over production, maintaining the excellent level of quality strongly desired by Alfredo Prunotto.
The production philosophy, attentive to every detail, and the great passion for wine, immediately united Prunotto with the Antinori family, who, in this area, faced a new challenge, a new terroir where the great territoriality of the native and non-native grape varieties could be expressed.
This project took shape in 1990, when Albiera Antinori, the eldest daughter of Marchese Piero Antinori, further defined the winery's personality, paying particular attention to the vineyards, first among which were the Bussia vineyard, one of the most renowned in the Barolo area, the Costamiòle vineyard in Agliano, for the production of Nizza, and lands in Calliano for the study and analysis of new grape varieties such as Albarossa and Syrah.
