Proper wine cellar climate control systems are a must in Australia. Home to some of the best New World wines in the industry, Australia is blessed with unique terroir that creates full-bodied, juicy wines with grippy tannins. It’s only natural to want to cellar some of our best cab sauvs and chardonnays. The problem? The same climate that allows Australia to grow such exceptional grapes can also make wine storage difficult.
The land of droughts and flooding rains lives up to its reputation, delivering boiling hot summers, freezing winters, and everything else in between. This intense variation means we can’t rely on a few layers of brick to maintain a stable climate, and most of us don’t have the space for a subterranean chamber. Professional climate control systems guarantee long-term wine preservation, creating the right environment for your collection to mature and improve over time. In this guide, we’re uncorking everything you need to know about wine cellar climate control.
Why Climate Control Matters for Your Wine Collection
Aside from the joy of collecting, one of the main reasons to cellar wine is to improve its flavour. A young wine will be loaded with tannins that can be a bit astringent or even acidic on the tongue. Time allows the tannins to mellow, giving the wine a plush mouthfeel while retaining flavour — if you age the wine correctly.
Incorrect storage can kill a wine faster than you’d think. Wine ages four times faster at room temperature, even when kept in a dark place. If the mercury rises above 20°C (as it often does during the summer), the heat can have a devastating effect. Fluctuations in temperature will quickly give the wine a spoilt taste and ruin the antioxidants and colour. Corks can dry out when the humidity drops too low, resulting in shrinkage and cracking. When a cork loses its seal like this, it causes air to seep into the bottle and ruin the wine through oxidation.
Lots of new wine collectors will start out by storing cases in their wardrobes, but this storage method just doesn’t cut it. The right wine cellar temperature and humidity are the difference between a great bottle and a ruined one.
Ideal Wine Cellar Temperature in Australia
Australia has such a varied climate, from the tropical humidity of Queensland to the heat of the Northern Territory, or the icy nights of Tasmania. While there’s a range of possible temperatures, none are consistently right for wine storage
The professional standard for wine cellar temperature in Australia is 12–18°C. Red wines have more tannins, allowing them to be aged more quickly than white wines. With this in mind, your favourite shiraz can be aged around 16–19°C. White wines require cooler temperatures for ageing, as they also need to be aged more slowly. An oaked chardonnay can easily be cellared for 10 years or more, but will do best around 10–12°C, while a sparkling needs a lower temperature to maintain its bubbles. If your collection is a mix of red, white, rosé, and sparkling wines, it’s best to aim for the middle at around 15°C.
Standard air conditioning units can’t achieve temperatures this low, and they certainly aren’t able to maintain temperatures as consistently as a cellar requires. Regular temperature fluctuations are as damaging to wine as heat, causing it to age years in just months and develop off-flavours.
Air Shepherd offers climate control systems specially designed for home wine cellars. These whisper-quiet units can be set to specific temperatures, so you can consistently nail the exact temperature your Penfold’s Grange needs for optimal ageing.
Humidity Control: The Silent Protector
The perfect environment for wine is a delicate balance of both temperature and humidity. When temperatures drop too far, the cold will cause the relative humidity (RH) to be too low. Insufficient humidity causes dried-out corks, which will eventually damage your wine. Meanwhile, if you go too far in the opposite direction, a high-humidity environment can breed mould. The last thing you want is for your cork to be compromised by mould (hello, corked vintage) or for your wine labels to start growing spores. Label damage quickly reduces the value of your cellared wine.
The ideal RH setting for humidity control in a wine cellar is between 50% and 75%. Within this range, corks remain properly moistened, ensuring they continue to hold a good seal. To keep things simple, we offer integrated systems that monitor and maintain both wine cellar temperature and humidity. You’ll be able to easily check your cellar’s humidity levels and get alerts if there is a change. We install our professional-grade climate control systems in conjunction with high-quality insulation and vapour barriers to prevent fluctuations.

Proudly designed and manufactured in Australia by Air Shepherd, the PH70 provides a dedicated, efficient, and reliable humidity-injection solution for premium wine storage environments.
Professional Climate Control Systems for Australian Homes
If your wine collection is more than a hobby, or you’re thinking of treating it as an investment at some point in the future, you need to get serious about professional climate control systems.
The reason aged wines are more valuable is due to their improved flavour. Tannins are softened, woody and spicy notes come to the fore, and fruity notes are made more complex and subtle. But wines aged in fluctuating or incorrect temperatures will taste nutty or like rotten fruit. With this in mind, vintage wine buyers will demand to see proof that your collection has been stored in a temperature-controlled environment.
You can maintain, or even increase, the value of your collection by using a professional service to install your wine cellar climate control system. As one of the best-loved wine cellar designers in the industry, Air Shepherd has a solid reputation for consistent, accurate climate control.

FAQs
What is the best wine cellar temperature in Australia?
For most mixed collections, the sweet spot is a stable 12–15°C with 60–70% relative humidity. Consistency matters more than chasing a single number — rapid swings ‘cook’ wine or dry out corks. If you’re cellaring specific varietals (e.g. robust Aussie reds), we can tune the setpoint within the broader 12–18°C range to suit your goals. Air Shepherd systems are designed for Australian conditions and keep temperature and humidity steady year-round, even in above-ground rooms.
Why does humidity matter in wine storage?
Humidity keeps corks supple so they seal properly. Too low and corks shrink, letting oxygen in and oxidising the wine; too high and labels spoil and mould can form. The safe range is 50–75% RH, with 60–70% ideal for presentation and longevity. Our climate control uses refrigeration-based humidity management (no messy water humidifiers), balanced airflow, and vibration damping to protect both the wine and its labels.
Get humidity control from the experts. Engineered for precision, our PH70 system delivers accurate and consistent humidity control, making it ideal for protecting prized cork collections and maintaining optimal cellar conditions.
Can I use a regular air conditioner for my wine cellar?
Short answer: no. Standard split systems are designed to cool people, not age wine. They strip moisture, cycle widely, and can’t hold cellar-grade stability, risking dried corks, flavour loss, and premature ageing. Air Shepherd units are purpose-built: whisper-quiet, humidity-aware, vibration-dampened, and trimmed to hold a tight cellar setpoint. They integrate neatly with wine walls, glazed doors, and custom racking.
Do I really need a climate control system for my wine cellar in Australia?
Yes — our climate is hot, variable, and unforgiving on wine. Even well-insulated rooms see seasonal peaks that push wine into the danger zone. Purpose-built climate control replicates underground-cellar conditions anywhere in the home or venue, preserving aroma, colour, and mouthfeel while protecting the value of your collection.
Bonus: a professionally built cellar is a high-impact feature that can lift buyer appeal and perceived property value.
