El Cep, for being a relatively new company, has the viticulture experience of the families that form part of the society. Some of them have been in the wine business since the 1600s. No irrigation. Fertilization is only done when the Petiole analysis shows a deficiency in any element. No herbicides are used. Cultivation is the only method of control of weeds. Odium and mildew are controlled with a Bordeaux mixture. The only insect pest is easily controlled with organic pesticide (Bacillus Turigiensis). Botrytis is still controlled with inorganic fungicides, but they are experimenting with alternative practices and other organic fungicides. Leaf removal, cluster thinning, and topping are practiced, to greatly improve quality, as well as to avoid the incidence of diseases. The vineyards are located Northeast of the Penedes, in the surroundings of Sant Sadurni D'Anoia (province of Barcelona). Grapes are sourced on 472.8 acres of vineyards in six different locations: Can Llopart, Cal Portaller, Can Simon, Can Prats, Can Castany, and Can Miguel de les Planes.
From around 1,500 tons of grapes harvested the winery uses 850 tons, depending on the years. Only healthy grapes and those coming from vineyards older than six years are used for their products. The vineyards are located in soft hills in very chalky soils.
