Like his fellow truffler Philippe de Santis, he lives in a ch?teau in oak-planted Alpine foothills. Every winter, from November to about March, Rocchia, de Santis and their fellow landowners pull on rubber boots and canvas jackets and set off to dig up a modest fortune-in the four month truffle season they might make a million French francs (?120,000). De Santis runs a small hotel, offering truffle cuisine, to maintain funds year round; while Rocchia at 58 has turned author, emulating his hero, ex-local millionaire Peter Mayle.
