Kahn was outraged at the results of the tasting, unsuccessfully demanded her ballot back, refused later to speak to organizer Steven Spurrier after the event, claimed fraud, and wrote disparagingly about the wine competition.

Kahn was an expert in the field of French gastronomy and wines, for which she was a well-known ambassador throughout the world.

After completing studies in business at HEC Jeunes Filles, she became assistant director and later editor-in-chief of two magazines, Cuisine et Vins de France [fr] and Revue du Vin de France.

In 1968, after the death of Madeleine Decure, Kahn became director of Société Française d'Éditions Vinicoles, publisher of Cuisine et Vins de France and Revue du Vin de France.

She participated in numerous radio and television broadcasts, and was a member of the jury in some of the most renowned gastronomic contests.
