Description Bunches of Barroca chaste grapes sit inside a plastic box at the vineyards of Quinta da Vista Alegre during the harvesting time, Portugal on Saturday, Oct 7, 2006. The harvesting in Douro starts by the beginning of September and ends by the first weeks of October. People who do the grapes' harvesting have to deal with extreme working conditions, from high heat to extremely difficult schistous rocky paths, heavy loads and all day long being bent to pick the grapes manually. Despite these difficulties, men and women, keep singing traditional Portuguese songs while they work, contrasting with the silence of the high hillsides and breath taking landscapes of the Douro valley.
