James Martin begins a road trip across the States in his latest daytime travelogue.

Combining fine food, a fascination with American culture and a love of fast cars, James and his crew will be travelling in style.

Today the chef hits Napa Valley, one of his favourite US destinations.

After blending his own red wine at one of the region’s famous vineyards, he sets up an outdoor kitchen to make some mouthwatering Californian dishes.

Continues tomorrow.
