At Finca La Rosenda, WWOOF (Willing Workers on Organic Farms) workers assist with the harvest and wine production. They stay in a small 'casita' built from mud, straw, bamboo and wine bottles. The owner of the finca, Virginia Leopardi, feels that the sense of collectivity among those who come to live on the vineyard and the joy of working together makes a real difference to the quality of their label. Each year, the last wine of the harvest is called 'the lunatic' as it's picked by the light of the full moon, when all their friends and volunteers gather for a harvest-closing party. ''It's about thanking Pachamama [the local indigenous earth goddess], showing we appreciate every time we go to harvest and loving everything that gives us this wonderful land'', says Leopardi.
