(Decanter) - Bordeaux's Saint Emilion classification is facing a fresh legal crisis after three chateaux filed complaints against the selection process. Chateau Croque-Michotte has joined Château La Tour du Pin Figeac and Château Corbin-Michotte to take their grievances before an administrative tribunal in Bordeaux. Tension has been simmering since France's appellation body, the INAO, published the long-awaited new Classification for Saint Emilion in September last year.
