GAS EXCHANGE DURING AGEING

For a long time, it was believed that a closed bottle was both watertight and airtight. In fact, exchanges take place between the gases inside and the air outside the bottle. Choosing to age bottles under cork or with metal crown caps will therefore significantly alter the nature of these exchanges.
