The biggest single client of La Cave Lyon is an Italian businessman who decided to store 13,000 bottles of great vintage wines in France.Like the guardian of a temple, Gangneux knows the stories behind labels, and bottles are synonymous with their owners."Over here, you have a client who lives in India. Twenty per cent of my clients live abroad," he added.
