Sustainability Guidelines of Marenco vinegrowing and winemaking

1. Erosion prevention thru permanent sod of the vineyard soil.
2. Organic matter amendment in the soil thru leguminous green manure.
3. Ban of invasive plowing.
4. Soil rest of minimum one year between removal of the old vineyard and plantation of the new one.
5. Preplantation manure with organic products used in minimal quantity , calculated on the base of the specific need of the specific soil.
6. Fertilization of the vineyard with minimal doses calculated according to the need of the specific vineyard.


1. Pest management executed exclusively with biodegradable products declared not harmful to the environment and human health.
2. 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).
3. Adoption of the practice of sexual confusion as an alternative to insecticide treatment whenever possible (eg moth).
4. Analysis on grapes and musts at harvest to verify the absence of pesticide residues.
5. Planting vineyards so that the rows run along the slope rather than up and down (need to be worked manually , but prevent erosion).


1. Production of electricity by photovoltaic panels installed on the roof of the cellar.
2. Use of light weight bottles to save glass and transportation costs.
3. Use of concrete tanks to fine young red wines , saving energy thru natural climatization.
4. No irrigation of vineyards. Save water and respect the natural course of the season.
5. Prohibition on the use of ascorbic acid and DMDC (dimethyl dicarbonate) for wine conservation.
6. Differentiated waste collection (paper, glass, plastic, agricultural, organic).



People and territory
1. Constant investment in research and development, improving the agronomic and oenological practices considering the climate change and the continuous aim to excellence.
2. Manpower recruited directly. Very limited use of cooperatives also during harvest.
3. Continuous training of qualified personnel.
4. Protection of indigenous varieties of the area (eg Caricalasino, Albarossa) performed by planting vineyards, vinification in purity of the variety, and the subsequent communication and marketing of the relative wine.
