While investing in wine is proving popular, preserving the “liquid assets” is often overlooked. However, one winemaker has been helping wine owners safeguard their prized assets for more than 25 years through its popular recorking service. Penfolds hosts dozens of recorking clinics around the world each year, and will be coming to Singapore in November. Recorking a bottle of wine is sometimes needed as wine corks deteriorate and lose their elasticity over time. This means the cork will no longer hold its tight seal, allowing air to enter into the bottle and causing the wine to evaporate. This evaporation introduces more oxygen into the wine, which over time will damage it. This can be very expensive if you have built up an impressive collection.
