Browse 1 question Browse 1 question and 1 answerHow do the caps absorb only the oxygen left in the head space of the bottle and not the oxygen in the air before they are put on the bottles?BEST ANSWER: The oxygen absorption is activated by moisture. Sanitize the caps then use them right away. Any that got wet can not be saved and still be effective at this. Cheers!
