One of the joys of wine is that there’s always something new to discover.
Whether it’s learning why some wines improve with age, understanding how oak influences flavour, or uncovering the secrets behind vintage variation, every bottle has a story to tell. At Ivanhoe Wines, we love helping our visitors deepen their appreciation of wine, because the more you understand it, the more enjoyable every glass becomes.
One question we’re occasionally asked is:
If wine is supposed to age in the bottle, why do some wineries open old bottles just to put a new cork in them?
The answer lies in one small but incredibly important part of every bottle.
The Cork Does More Than Seal the Bottle
Natural cork is an extraordinary material.
It creates a seal that protects the wine while still allowing microscopic amounts of oxygen to enter the bottle over many years. This slow exchange helps certain wines develop greater complexity as they age.
However, cork is a natural product, and like anything natural, it doesn’t last forever.
After decades in the bottle, a cork can begin to dry out, shrink or lose its elasticity. When that happens, excess oxygen can enter the bottle, accelerating oxidation and potentially spoiling a wine that may have taken decades to mature.
What Is Recorking?
For some of the world’s most collectible wines, wineries offer a service known as recorking or reconditioning.
The process involves carefully opening an aged bottle, assessing the condition of the wine and replacing the old cork with a new one. If a small amount of wine has evaporated over the years – a phenomenon often called the “angel’s share” – the bottle may also be topped up with a wine of the same style or vintage before being resealed.
The goal isn’t to change the wine.
It’s simply to preserve it for many more years of cellaring.
Why Don’t All Wineries Offer It?
Recorking is a highly specialised process.
Every bottle must be inspected individually, and the wine itself must still be in excellent condition before a winery will consider replacing the cork. Some renowned producers even hold dedicated recorking clinics where collectors can have treasured bottles professionally assessed and preserved.
For most wineries, however, recorking isn’t practical or necessary.
Modern cork technology has improved significantly, and wines intended to be enjoyed within the first decade or two of release rarely require intervention.
Should You Recork Your Own Wines?
For the vast majority of wine lovers, the answer is no.
Recorking is best left to the original winery offering the service, where experienced winemakers have access to the correct corks, replacement wine (if required) and the knowledge to assess whether the bottle is suitable for continued ageing.
If you have a treasured bottle that’s several decades old, opening it is often the best way to enjoy the rewards of careful cellaring.
After all, wine is made to be shared.
Cellaring an Older Ivanhoe Vintage?
Recorking isn't a service we offer at Ivanhoe Wines, and for the vast majority of our wines, it isn't something that's ever likely to be needed. Even so, we're always glad to talk through the finer points of cellaring with anyone who's been holding on to an older vintage.
If you have an older Ivanhoe wine you've been saving for a special occasion, get in touch with our team. We're happy to chat about the wine's age, offer guidance on whether it's ready to enjoy, and share what we know about how it's likely to be ageing. Helping you get the very best from every bottle is all part of the Ivanhoe experience.
Continue Your Wine Education at Ivanhoe Wines
Of course, you don’t need a decades-old bottle to learn something new about wine.
The best way to deepen your appreciation is with a glass in hand. When you visit the Ivanhoe Wines cellar door, our team will guide you through a tasting of our Hunter Valley wines while sharing the stories, techniques and traditions behind every bottle. It’s a relaxed and enjoyable way to build your wine knowledge and discover the craftsmanship that goes into every vintage.
Book your next tasting and experience Ivanhoe Wines for yourself. We look forward to sharing a glass—and perhaps teaching you something new along the way.
