Duemani winery was founded in 2000 by the initiative of Elena Celli and oenologist Luca D'Attona in Riparbella, province of Pisa, a place where they decided to give life, as a shared challenge, to their biodynamic project: "... an extreme and grumpy place, with predominant clay and a strong presence of stones, uncultivated for years and surrounded by Mediterranean scrub. An hill that smells of sea and forest, facing the coast at an altitude of about 250 meters. Here are sun, light and continuous breezes that guarantee thermal excursions, determining for the perfumes and for a slow maturation, a guarantee of perfect balance." Soils placed on a large clod of white tuff, mixed with stones and clay for almost 40%. "Extreme" terroir, that some scientific analyzes gave as not suitable, but which represented - also for this reason - a challenge with oneself, nature and the "conventional" way of understanding viticulture. To support this venture is François Bouchet, a master of biodynamics, who judges the soils of Riparbella absolutely exceptional, extreme of course, but ideal for making fully organic wines. This is how this splendid winery was born, on a slope with a characteristic amphitheater conformation, where three vineyards are cultivated: in the highest part is located Cabernet Franc, further down Merlot and in the middle the heart of the winery, a small vineyard Syrah bred in alberello, which is born on a particularly stony and arid soil. In 2014 the production is integrated with a Cabernet Franc 's vineyard of 3 hectares, placed 350 meters above sea level and located in the beautiful valley around the winery, thus reaching a total of 10 hectares of vineyards. This winemaking reality is one of the few in Italy to have the Demeter biodynamic certification, the oldest existing (dating back to 1927) and today spread in 43 Countries, which, through the Italian headquarters, carries out a careful control on production, transformation and marketing of biodynamic products, through rather restrictive rules.
