Whether you’ve just started collecting premium Australian wine or you’re a hospitality veteran managing a high-turnover cellar, the goal of a wine cellar is the same: preservation. In a climate as unforgiving as ours, the difference between a sublime tasting experience and a wasted investment often comes down to environmental factors, such as wine temperature and wine humidity.
At Air Shepherd, we’ve spent over 60 years mastering the variables that turn a simple room into a world-class vault. To help you navigate the complexities of maturation, we’ve put together the ultimate guide on the best way to store wine, ensuring every bottle you cork is exactly as intended.
The Essentials: Temperature & Humidity
DO: Prioritise Wine Temperature Consistency
Stability in your storage environment is key. Rapid changes in wine temperature cause the liquid to expand and contract, putting pressure on the cork and potentially allowing oxygen to seep in.
For long-term ageing, aim for a steady environment of 12–14°C. Our wine storage temperature guide goes into detail on the ideal temperature ranges for different wine varieties (such as 7–12°C for white wine and 12–19°C for red wine). That said, the golden rule is to avoid any space that swings more than a couple of degrees in a 24-hour period. If your wine cellar or storage area doesn’t have a digital thermometer built in, you can use a handheld wine thermometer to check.
DO: Manage Your Wine Humidity
Wine humidity is the most overlooked factor in home storage. If the air is too dry (below 50%), the corks can dry out, shrink, and let air into the bottle. If it’s too damp (above 75%), you’ll soon find mould growing on your labels — a nightmare for the resale value of a rare vintage.
A dedicated wine cellar humidifier is the most reliable way to maintain that “sweet spot” of 60–70% relative humidity in a sealed wine cellar. Unlike standard household humidifiers, these are designed to work in the cool environment of a cellar without oversaturating the space.
Storage Setup: Racking & Light
DO: Invest in Custom Wine Rack Storage
As far as wine storage tips go, the way you physically store your bottles matters more than you think. Horizontal wine rack storage is essential for any bottle finished with a natural cork, as it keeps the wine in contact with the cork, preventing it from drying out.
Traditional timber can actually warp or hold moisture, which is why we specialise in custom steel fabrication. Steel shelving offers a minimalist aesthetic and allows for better airflow around the bottles, which is critical for maintaining an even temperature throughout the wine cellar. Steel also has a higher weight-bearing capacity than wood, so you can stack more wine bottles on steel racks than on wooden racks while using much slimmer racking. This makes steel an ideal choice for growing collections.
It’s also worth considering which wines you prefer to drink when planning your cellar, as some varieties come in larger bottles and therefore require more rack space. For example, Burgundy wines traditionally come in wider bottles.
DON’T: Let Light In
UV light is the enemy of wine. It triggers chemical reactions that lead to “light strike,” giving the wine an unpleasant, damp-cardboard aroma. While glass-fronted wine walls are stunning, they should be built with UV-protected glazing. If you are designing a display, always use cool LED lighting that doesn’t emit heat or harmful rays.
Frequently Asked Questions
What is the ideal temperature for storing wine, and why is consistency important?
Aim for 12–14°C for long-term storage, while the acceptable short-term range is 10–15°C. The optimal temperature varies between wine types. For example, sparkling wine like prosecco would ideally be stored at 5–7°C, whereas the preferred storage temperature for a full-bodied red like cabernet sauvignon is 16–19°C. To make it easier, we’ve written an article covering the various ideal wine temperatures that you can use as a guide. If you can’t hit these exactly (perhaps because you need to store multiple wine varieties in one place), focus on consistency and on avoiding heat sources. Fluctuations cause the bottle to “breathe” through the cork. This introduces oxygen, which accelerates ageing and gives your wine an unpleasant sour taste.
What is the recommended humidity level for wine storage?
We recommend maintaining a humidity level between 50% and 70%. This keeps the cork hydrated and airtight while protecting the integrity of the paper labels and preventing mould growth.
What are the worst places in a home to store wine?
The worst spots are near heat, light, or vibration sources (e.g. oven, dishwasher, the top of a refrigerator or washing machine — which emits constant heat and vibration), or any cupboard against an uninsulated west-facing wall. These areas subject the wine to the most extreme environmental stress.
Wine Storage Tips In Practice: From Home Walls to Hospitality
The best way to store wine depends on your specific space and collection goals. At Air Shepherd, we apply our 60 years of combined expertise to tailor wine rack storage and climate solutions to these common scenarios:
- Small Apartments or Compact Spaces: If a full cellar isn’t an option, a well-ventilated wine cabinet or dedicated wine fridge is your best bet. As a last resort, you can store your wine in a low pantry shelf or under internal staircases. Ensure your storage space is kept off exterior walls and away from sunny windows to avoid the heat spikes common in our climate.
- Serious Home Collectors: For those investing in long-term maturation, we recommend installing a custom-designed, climate-controlled cellar. Integrating a dedicated wine cellar humidifier ensures your corks stay hydrated, protecting the value of your collection for years to come.
- Hospitality & Restaurants: Whether it’s a visible wine wall or a dedicated underground cellar, venue owners must prioritise strict quality control, especially when rotating inventory.
- Temporary Storage & Gifting: If you are moving or holding a gift, find the coolest, darkest spot available. Avoid hot cars at all costs; even a short trip in the sun can cause the wine to expand and compromise the seal.
