The Tenute Cisa Asinara dei Marchesi di Gresy, made up of three estates situated in the Langhe and Monferrato zones, is recognized for producing many of the greatest wines in the Piedmont region. After years of selling grapes from the estate to the region’s top producers, in 1973 Alberto di Gresy began vinifying his own wine with the objective of producing wine using modern technology while respecting tradition, and to transferring as much of the character of the terrain, vineyard site and varietal into the bottle. The Martinenga estate, the only monopole in Piedmont grows primarily Nebbiolo grapes for the production of Barbaresco as well as Barbera and Cabernet Sauvignon. Also, at Martinenga, are newer vineyards of Sauvignon Blanc and Chardonnay. Nearby in the Commune of Treiso d’Alba is the Monte Aribaldo estate where Dolcetto d’Alba is grown. In Monferrato, the La Serra estate produces exclusively Moscato dAsti. Martinenga, with its 11 hectares of Nebbiolo vines, is considered to be one of the greatest single vineyards dedicated to the production of Barbaresco. Its ideal southern exposure and blue marl soils produce fruit that is transformed into a Barbaresco of extraordinary class and finesse.
