You could be forgiven for feeling something of an underachiever following a trip to HALL, the ambitious state-of-the-art boutique winery on the outskirts of St Helena in California’s Napa Valley. Created in 2002 by serial entrepreneur Craig Hall and his wife Kathryn Walt Hall, the property is founded on the site of the old Napa Valley Co-Op. The centerpiece is a stunning new winery and tasting room, given an almost transparent air with floor to ceiling glass. In contrast, set beside it, is the renovated stone Bergfeld Winery established in 1885. Works of art are dotted about the gardens, including a giant silver rabbit that jumps Watership Down-like, out of the vineyard, as if making a bid for the St Helena Highway out in front.
