Frequently Asked Questions
We don’t re-cork wine unless necessary, as it can only be done once. When a bottle is opened, it undergoes oxygenation; therefore, specialised tools are used by our winemakers to reduce the impact on the wine. A very small amount is poured from the bottle to assess, and the bottle is then topped up with the current vintage of that wine, arresting any further deterioration due to leakage or low levels. Some collectors investing via thesecondary marketprefer to purchase a re-corked bottle as the condition has been certified, therefore minimising risk.
To qualify for an appointment at our clinics, your red wine must be fifteen years or older and can’t have been re-corked previously. Should you have purchased your wine through the secondary wine market and it has been re-corked before, you’ll find a certification label on the back of the bottle signed by a winemaker. Ideally, your wine has been well-cellared and has good ullage.
