Marenco's history dates back to 1925s and grandfather Michele’s dream of making wine from his vineyard in the heart of the Bagnario Valley, Strevi, an area especially suitable to viticulture. His son Giuseppe then began the Company’s evolution, gradually acquiring the best land of the Monferrato and choosing the most typical grape varieties to plant.
In 1956, he built his winery in the centre of the village of Strevi, to be near the train station so that he could send his wines directly to his customers. A man with deep roots, he was able to convey his passion to the entire family, and today his daughters , Michela, with her husband Giovanni Costa, Patrizia, and Doretta carry on “the family dream ” with his same enthusiasm and dedication. They personally supervise and control every step of the production process, all the way from grape to glass. Andrea Costa, Michela and Giovanni’s first son, joined the company in 2014. Bringing his background of engineer in international companies, and some academic studies in winemaking, he is introducing new innovation projects both in the vineyards and cellar.
Excellence is the company’s priority , choices are driven by the desire to express with our wines the excellent flavours of our corner of Piedmont. Marenco's connection to the land and to local traditions and their deep respect for nature and the environment is continuous and daily. Even the Company logo, two mallards in flight, was inspired by their land, the lake at the Bassina Estate in Fontanile.
- Erosion prevention thru permanent sod of the vineyard soil.
- Organic matter amendment in the soil thru leguminous green manure.
- Ban of invasive plowing.
- Soil rest of minimum one year between removal of the old vineyard and plantation of the new one.
- Preplantation manure with organic products used in minimal quantity, calculated on the base of the specific need of the specific soil.
- Fertilization of the vineyard with minimal doses calculated according to the need of the specific vineyard.
- Pest management executed exclusively with biodegradable products declared not harmful to the environment and human health.
- Monitoring thru weather stations installed in the vineyards of the specific environmental conditions. Consequent eventual phytosanitary treatment according to the specific needs (no calendar treatment).
- Adoption of the practice of sexual confusion as an alternative to insecticide treatment whenever possible (e.g. moth).
- Analysis on grapes and musts at harvest to verify the absence of pesticide residues.
- Planting vineyards so that the rows run along the slope rather than up and down (need to be worked manually, but prevent erosion).
- Production of electricity by photovoltaic panels installed on the roof of the cellar.
- Use of light weight bottles to save glass and transportation costs.
- Use of concrete tanks to fine young red wines , saving energy thru natural climatization.
- No irrigation of vineyards. Save water and respect the natural course of the season.
- Prohibition on the use of ascorbic acid and DMDC (dimethyl dicarbonate) for wine conservation.
