Douglas Blyde discusses the world of Prosecco with winemaker Primo Franco of producer Nino Franco

Primo Franco, of Prosecco producer, Nino Franco, marked 30 years since he produced his first vintage by hosting a lunch at Hawksmoor restaurant, Air Street, Mayfair. Franco mentions that his choice of restaurant - the latest in the clubby Hawksmoor quartet, and first to offer dishes devised by celebrity fisherman, Mitch Tonks alongside signature steak - happens to lie close to the recently-refurbished five star, Café Royal. It was in those kitchens during the early 1970s, explains Franco with a wry smile, that he toiled as a kitchen porter. After his first shift, during which he confronted "an endless seeming conveyor of dishes", the disorientated, young navvy found himself spending the bulk of his earnings on the taxi home to Acton.
