Mass produced wine is filtered and sulphites are added to prevent oxidation. Sulphites are ions composed of sulphur and oxygen, which naturally exists in wine in the form of sulphur dioxide, a preservative which has antibacterial and antioxidant properties, and are not harmful. The vintage may be bottled at the winery, or if it is to be shopped it is placed in bladders, and more sulphites are added for the journey.
High quality wines are bottled on the premises, and a very small amount of sulphites may be added. In general they have less extra chemicals than mass-produced wine, because more time and effort has been put in to create the drink, from picking grapes by hand to keeping red wine in oak barrels. In short, the wines we look after in our vaults are not comparable to the bottled wines that run up and down the supermarket aisles.
So, we hope you learnt a bit about the differences in the processes of creating a high-class vintage compared to a mediocre drink. If you wish to ask a bit more about our wine storage at Octavian call us on +44 (0)1225 818714, or send us a message via our contact form.
