Zusammenfassung:	The invention concerns a method for treating a cork-based product useful for making stoppers. The invention is characterised in that it comprises the following steps: a) introducing the product in a sealed container; b) subjecting said product to the action of water vapor under pressure ranging between 2.105 and 30.105 Pa for a duration ranging from about 5 seconds to 5 minutes; c) producing an expansion to restore atmospheric pressure inside the container; d) recuperating the treated product.
