Vineyards usually sit happily on country hillsides, way out of the city smog, but you’ll find a few urban wineries around the world, from Clos Montmartre in Paris to D’Augustine Vineyard in Los Angeles.

A new project in Sydney aims to take that concept even further by creating the world’s largest urban vineyard by “crowd-planting” vines across the city.

Australia’s very first vineyard was planted in the centre of the city in 1791, on Macquarie Street in the CBD. Now, the The Urban Vineyard Project, a promotional activity launched by online wine retailer Cracka Wines, will encourage locals to plant a “connected” vineyard across the city, in people’s backyards, balconies, and windowsills.

Cracka will give away thousands of pinot noir and riesling grapevines through their website for free — they just gave out the first batch at Sydney’s Wine Island festival last weekend.
