I have been surprised by a new innovative project of Ferran Adriā ( the best chef in Spain) that is called " Buy a Vineyard". For 59 euros/month you have the chance of manage your own vineyard, design your future wine ( with the support of specialists) that will result of the grapes( chosen by you) of the vineyard.
Every year you will receive your 42 bottles with your own labels , designed by you. You can manage your own vineyard by internet(controlled by webcam and videoconferencing) or coming directly at the vineyards. The vineyards are situaded in Conca de Barberā in Catalonia
D.O Conca de Barberā I think it's sounds good. It is clearly not an investment but it is a very good oportunity to be involved in the wine's culture, learning and sharing with other owners experiences and knowledges about your vineyard. Also is a very excelent idea if you want to surprise your family or friends in a "special day" with your own wine.
