Candles are a great way to add ambiance and fragrance to a room, but what happens if they're stored in cold temperatures? While candles don't typically have an expiration date, extreme temperatures can interfere with their fragrance and wax consistency. Proper candle care includes storing them in a cool, dry place, away from direct sunlight, and extreme heat or cold. This helps maintain their scent and appearance. Scented candles, in particular, have an average lifespan of 3-4 years and proper storage can extend their longevity. Additionally, the type of wax and ingredients used also play a role in how long a candle lasts. Natural waxes like soy, beeswax, and coconut may have a shorter shelf life, while paraffin candles can last almost indefinitely with proper storage.
| Characteristics | Values |
|---|---|
| Lifespan of candles | Depends on ingredients, type of wax, fragrance, and storage conditions. Paraffin candles can last almost indefinitely, while soy candles are best used within a year or two. Beeswax candles can last several years. |
| Scent degradation | Scent degradation happens gradually and may not be noticeable for the first 6 months to a year. Older candles may not smell as strong, but the fragrance oils are still present inside the candle. |
| Colour degradation | Candles with coloured wax may fade over time due to exposure to UV light, causing the dyes to oxidize and degrade. |
| Storage | Store in a cool, dry, dark place to prevent fragrance loss and maintain consistency of wax. Avoid extreme temperatures as they can interfere with the fragrance and wax consistency. |
| Proper burning | The first time you burn a candle, let the wax melt all the way across the surface to prevent tunneling issues. Trim the wick before each use and ensure it is no longer than 1/4 inch above the wax to prevent an uneven burn. |

What You'll Learn
Candles exposed to cold may lose their scent
Candles are a great way to create a cosy atmosphere and fill a room with a pleasant fragrance. However, they can be sensitive to temperature changes and extreme cold can cause issues.
While candles do not have an expiration date, their scent and appearance can degrade over time. Cold temperatures can accelerate this process, causing the wax to become dry and brittle and the fragrance to weaken or disappear. This is because the fragrance oils in the candle can evaporate or break down over time, especially when exposed to cold temperatures. The wax can also absorb moisture and outside scents, which can alter the original fragrance.
To prevent this, it is recommended to store candles in a cool, dry place, away from extreme temperatures and direct sunlight. Glass jar candles with airtight lids can help to keep the fragrance from leaching into the air and protect the candle from degradation.
If you have a candle that has been exposed to cold temperatures, it may still be safe to burn, but the fragrance may be weaker or different from when you first purchased it. To check if a candle has lost its scent, try scratching the surface gently or holding it close to your nose to see if you can detect any fragrance.
Additionally, candles stored in cold temperatures may develop cracks or changes in their appearance. While these candles may still burn, they may not provide the same luxurious experience as when they were first purchased.

Cold can alter the consistency of candle wax
Candles can expire, and extreme temperatures can interfere with both a candle's fragrance and the consistency of its wax. Cold temperatures can cause the wax to become brittle and crack, which can make it difficult to light the candle and control how it burns. The cold can also cause the wax to contract, which can lead to gaps or cracks in the wax.
The type of wax in a candle affects how susceptible it is to cold temperatures. For example, candles made with natural waxes such as soy, coconut, or beeswax may be more likely to be impacted by cold temperatures than those made with paraffin wax. These natural waxes tend to have a slightly shorter shelf life than paraffin candles.
Additionally, cold temperatures can affect the fragrance of a candle. The fragrance of an unlit candle, known as the cold throw, weakens with age. The scent of a candle is typically at its strongest when the candle is first purchased, and it gradually degrades over time, even if the candle remains unused. This process is accelerated by extreme temperatures, causing the fragrance to evaporate more quickly.
To prevent candles from being affected by cold temperatures, it is recommended to store them in a cool, dry place, avoiding extreme temperatures and drafts. Keeping candles in airtight containers or sealed glass jars can also help to preserve their fragrance and protect them from the cold.
By taking these precautions, you can help ensure that your candles remain in optimal condition and that their wax maintains its intended consistency.

How to store candles in cold weather
While candles do not exactly "go bad" in the cold, improper storage can lead to loss of fragrance, colour fading, structural damage, and reduced burn time. Here are some tips to help you store your candles effectively during cold weather:
Store in a cool, dry place:
Avoid extreme temperatures when storing your candles. Aim for a room temperature of between 50°F and 85°F. Extreme cold can cause the wax to become brittle and crack, while excessive heat can interfere with the fragrance profile and wax consistency. A cool, dry place, such as a basement, linen closet, or hallway cabinet, is ideal for maintaining the quality of your candles.
Avoid direct sunlight and other heat sources:
Keep your candles away from direct sunlight and heat sources like heaters or stoves. Prolonged exposure to UV light can cause the candle colours to fade and the wax to degrade. Store them in a dark place, such as inside a cabinet or drawer, to protect them from light exposure.
Use airtight containers:
Glass jar candles with airtight lids help preserve the fragrance and protect the candle from dust and other contaminants. If your candles did not come with lids, you can mimic this technique by storing them in sealed, airtight containers.
Store candles upright to prevent warping:
Most candles should be stored upright to prevent warping or bending. However, taper candles are an exception and should be stored flat to prevent damage. For delicate or uniquely shaped candles, consider using bubble wrap or a soft cloth for added protection.
Keep away from flammable items:
Always prioritise safety when storing your candles. Keep them away from anything that can easily catch fire, such as flammable liquids or materials.
By following these tips, you can effectively store your candles during cold weather, preserving their fragrance, colour, and structural integrity for optimal burning experiences.

How to prevent candle wax from cracking in the cold
Candles can be a great way to create a cosy atmosphere, but they can lose their appeal if the wax cracks in the cold. Here are some tips to prevent this from happening:
Store in a Cool, Dry Place
Avoid exposing your candles to extreme temperatures, including extreme cold. Store your candles in a cool, dry place, such as a cupboard or pantry, to maintain their optimal condition.
Avoid Direct Sunlight
If your candle is coloured, be aware that its colour may fade over time due to exposure to UV light. Keep coloured candles away from direct sunlight and strong indoor lighting to prevent discolouration.
Use Airtight Containers
To prevent your candle's fragrance from dissipating and to protect its wax from the cold, store it in an airtight container. Glass jars with airtight lids are ideal for this purpose, preserving the scent and consistency of the wax.
Choose the Right Type of Candle
Different types of candles have varying shelf lives. Beeswax candles, for instance, are known for their longevity and can last several years without deterioration. On the other hand, soy candles are best used within a year or two, as their fragrance may fade, and they may not burn as evenly.
Proper Burning Techniques
The first time you burn your candle, ensure the wax melts all the way across the surface. This helps prevent "tunnelling" issues and extends the life of your candle. Additionally, remember to trim the wick before each use to promote an even burn and prevent the flame from becoming too hot, which can negatively impact the candle's lifespan.
By following these simple steps, you can enjoy your candles without worrying about wax cracking in the cold.

How to tell if a candle is too old to burn
While candles do not technically "expire", there are some ways to tell if your candle is too old to burn. Firstly, check the colour of the candle. If the candle was once a vibrant colour, such as red, and has now faded to a duller shade, it is likely too old. Similarly, if a candle was originally colourless and has now turned yellow, it has probably expired.
Another way to tell if a candle is too old is by its scent. Scent degradation happens very gradually, but it is always happening. If you are struggling to detect a scent, gently scratch the surface of the candle, and if there is still no smell, it has likely expired.
You can also look out for signs of degradation in the wax. If the wax has split, formed a coating on the surface, or become dry and cracked, the candle is likely too old. Additionally, if the candle gives off a rotten or foul stench, it should be thrown out.
Finally, if you have burned your candle for a long time, it may be time to replace it. Most candles should not be burned for longer than four hours at a time, and you should stop burning a candle when there is about half an inch of wax left to prevent overheating and potential breakage.
