How Long Does Bottled Water Last

Factors Affecting the Shelf Life of Bottled Water

When it comes to bottled water, there are several factors that can affect its shelf life. The type of bottle used, the storage conditions, and the quality of the water itself all play a role in determining how long the water will stay fresh and safe to drink.

1. Type of Bottle

The type of bottle used to store the water is an important factor in its shelf life. There are primarily two types of bottles commonly used for bottled water: plastic bottles and glass bottles.

1.1 Plastic Bottles

Plastic bottles are the most commonly used packaging for bottled water. There are different types of plastic bottles, but the three most popular ones are PET (polyethylene terephthalate), HDPE (high-density polyethylene), and other types of plastic bottles.

1.1.1 PET Bottles

PET bottles are lightweight, durable, and have good resistance to impact. They are commonly used for single-use bottled water. PET bottles are easy to recycle and have low manufacturing costs. The shelf life of water in PET bottles is generally recommended to be within two years from the date of manufacture.

1.1.2 HDPE Bottles

HDPE bottles are known for their strength and resistance to chemicals. They are commonly used for larger water containers, such as those used in home water coolers. HDPE bottles have a longer shelf life compared to PET bottles, with water typically remaining safe to drink for up to five years.

1.1.3 Other Types of Plastic Bottles

There are also other types of plastic bottles used for bottled water, such as PVC (polyvinyl chloride) and PP (polypropylene) bottles. These bottles have different characteristics and common uses, but their shelf life for storing water can vary. It is important to check the manufacturer’s recommendations for each specific type of bottle.

1.2 Glass Bottles

Glass bottles are less commonly used for bottled water due to their weight and fragility. However, they are known for their ability to preserve the taste and quality of water for longer periods of time.

Glass bottles have a significantly longer shelf life compared to plastic bottles, with water typically remaining safe to drink for an extended period, even up to several years.

2. Storage Conditions

The way bottled water is stored can have a significant impact on its shelf life. Several factors should be taken into consideration when storing bottled water:

2.1 Exposure to Sunlight

Bottled water should be stored away from direct sunlight. Exposure to sunlight can lead to the degradation of certain compounds in plastic bottles, such as phthalates, which can potentially affect the taste and quality of water. Furthermore, sunlight exposure can lead to the growth of algae or bacteria in the water, thus reducing its shelf life.

2.2 Temperature

Extreme temperatures can also impact the shelf life of bottled water. High temperatures can accelerate the degradation of the plastic bottle, leading to the release of chemicals into the water.

On the other hand, very low temperatures can cause the water to freeze and expand, potentially resulting in a damaged bottle or a compromised seal. It is recommended to store bottled water at a moderate temperature, ideally between 50°F and 70°F.

2.3 Humidity

Humidity can affect the integrity of the bottle’s seal, potentially allowing contaminants to enter the water. It is advisable to store bottled water in a cool, dry place to prevent moisture buildup and ensure the bottle remains tightly sealed.

2.4 Proximity to Chemicals

Bottled water should be kept away from chemicals, such as cleaning agents, solvents, or gasoline. These substances can potentially contaminate the water, compromising its safety and shelf life. It is crucial to store bottled water in a separate area away from any potentially harmful chemicals.

3. Quality of Water

The quality of the water itself is a crucial factor in determining its shelf life. Two aspects that greatly influence the quality of water are its source and the treatment and purification processes applied.

3.1 Source of Water

The source of the water used for bottling plays a significant role in its overall quality. Water that comes from natural springs or underground wells often has lower levels of contaminants compared to water from other sources. Additionally, water sourced from protected areas or municipal water supplies that undergo rigorous testing are likely to have better quality and a longer shelf life.

3.2 Treatment and Purification

After sourcing the water, it undergoes various treatment and purification processes to ensure its safety and quality. Processes such as filtration, disinfection, and reverse osmosis remove impurities and microorganisms that can affect the shelf life of the water.

The effectiveness of these processes, along with strict quality control measures, contribute to the longevity of the water’s freshness.

4. How Long Does Bottled Water Last?

Determining the shelf life of bottled water involves checking for two important dates: the expiry date and the best before date.

4.1 Expiry Date

The expiry date indicates the last day on which the water is guaranteed to be of optimal quality and safety. It is essential to consume bottled water before the expiry date to ensure its freshness and taste.

4.2 Best Before Date

The best before date refers to the recommended period during which the water is expected to retain its qualities, including taste, odor, and nutritional value. While the water may still be safe to drink after the best before date, its overall quality might gradually decline.

4.3 Effects of Storage Conditions

Storage conditions, as discussed earlier, have a significant impact on the shelf life of bottled water. Proper storage in a cool, dry place away from sunlight, chemicals, and extreme temperatures can help maintain the water’s freshness and safety for a longer time.

4.4 Testing the Water

If you are unsure about the quality or safety of bottled water, there are test kits available that allow you to check for potential contaminants. These kits can help in determining if the water is still suitable for consumption, especially if stored for an extended period.

In conclusion, the shelf life of bottled water is influenced by various factors such as the type of bottle, storage conditions, and the quality of the water itself.

Understanding these factors and following proper storage guidelines can help ensure that your bottled water retains its freshness and remains safe to consume. Remember to always check the expiry date and best before date, and consider the effects of storage conditions on the water’s overall quality.
