Grape pickers dance while treading grapes in a traditional stone tank at Quinta do Vesuvio vineyard, Sept. 19, near the village of Foz Coa, northern Portugal. After spending the day picking grapes on the slopes of the Douro Valley, in the evening the workers tread the grapes to be used in the production of Port wine. Port wine sales have been falling steadily since the turn of the century, jeopardizing the livelihoods and way of life of thousands of people along the Douro Valley. Picture received Oct. 23.
