2016 Screaming Eagle, The Flight, Oakville, Napa Valley, California, USA

Cabernet Franc is widely planted in Bordeaux and is the most important black grape grown in the Loire. In the Médoc it may constitute up to 15% of a typical vineyard - it is always blended with Cabernet Sauvignon and Merlot and is used to add bouquet and complexity to the wines. It is more widely used in St.Emilion where it adapts well to the cooler and moister clay soils - Cheval Blanc is the most famous Cabernet Franc wine in the world, with the final blend consisting of up to 65% of the grape.

Screaming Eagle is one of the original Californian "cult wines". Proprietor Jean Philips never dreamt that her wine would be so sought after, when in 1992, after years of selling grapes to Napa Valley wineries, she decided to find out if her home-made wine, created in a plastic trash can, was any good. She took a sample down to Robert Mondavi where they thought enough of her dark, rich, cassis-flavoured Cabernet to encourage her to bottle it, though they snickered at her proposed name. The rest is history.
