World's biggest hand-harvester?

I'm just back from New Zealand, where I learnt to my astonishment that Craggy Range, the Hawke's Bay-based winery, are hand-harvesting, weather permiting (as it did in 2008), their entire 250-ha (600-odd acres) of vineyards. Yup, even the sauvignon blanc.

My question is, who in the world can top this? I've read that sometimes Yquem can go through their 250acres (100ha) five or six times in a tough year.

Any other candidates? Or is it more common than I thought?
cheers,

Hmmm, I'd suspect that Mondavi's Napa and Carneros holdings were all hand-harvested, at least until recently. The Huichica vineyard in Carneros alone is nearly 600 acres. Then there's Andy Beckstoffer's holdings in Napa, Mendocino and Lake counties, part of which are surely hand-harvested. The Napa holdings are over 800 acres. I wonder how much of KJ's vineyards are hand-harvested?
