Yes, you can generally drink bottled water that is two years past its expiration date, but it’s not ideal. While the water itself doesn’t typically spoil, the plastic bottle can degrade over time, potentially leaching chemicals into the water and affecting its taste. It’s always best to consume bottled water before its expiration date for optimal quality and safety.
Is Expired Bottled Water Safe to Drink? Understanding the Risks
Many people wonder if that dusty bottle of water in the back of the pantry is still good to drink. The short answer is: yes, you likely won’t get sick from drinking bottled water that’s two years past its expiration date. However, there are important considerations regarding taste, quality, and potential chemical leaching that make it less than ideal. The expiration date on bottled water isn’t about the water spoiling like milk or food; it’s more about the integrity of the packaging and the potential for taste degradation.
Why Do Water Bottles Have Expiration Dates?
Bottled water manufacturers include expiration dates primarily for quality assurance, not because the water itself becomes unsafe in the way perishable foods do. These dates, often referred to as "best by" or "use by" dates, typically range from one to two years from the bottling date. The main concerns revolve around the plastic bottle and its interaction with the water over extended periods.
The Role of the Plastic Bottle
Most bottled water comes in PET (polyethylene terephthalate) plastic bottles. While PET is considered safe for food and beverage contact, it’s not entirely inert. Over time, especially when exposed to heat or sunlight, the plastic can begin to degrade. This degradation can lead to:
- Chemical Leaching: Small amounts of chemicals from the plastic can migrate into the water. While generally considered safe in small quantities, prolonged storage can increase this leaching.
- Taste Alteration: The plastic itself can impart a slightly "plastic" or stale taste to the water, diminishing its refreshing quality.
- Bacterial Growth (in opened bottles): Once opened, any water, expired or not, can become contaminated with bacteria from the environment or from your mouth. Always refrigerate opened bottles and consume within a few days.
What About Glass or Other Containers?
Bottled water in glass bottles or stainless steel containers generally has a much longer shelf life without significant degradation concerns. These materials are more inert and less prone to leaching or affecting the taste of the water. However, the water inside can still become stagnant or pick up odors from the environment if not sealed properly.
What Happens When You Drink Expired Bottled Water?
Drinking bottled water that is a couple of years past its expiration date is unlikely to cause immediate harm. Your body is quite adept at processing small amounts of foreign substances. The primary effects you’ll likely notice are:
- Off-Taste: The water might taste flat, stale, or have a distinct plastic flavor.
- Reduced Freshness: It simply won’t taste as crisp and clean as freshly bottled water.
The long-term health risks associated with occasional consumption of slightly past-date bottled water are generally considered very low by most health organizations. However, for consistent hydration and the best possible taste and quality, sticking to the expiration date is advisable.
How to Store Bottled Water for Longevity
Proper storage can significantly extend the quality of bottled water, even beyond its printed expiration date. Here are some best practices:
- Cool, Dark Place: Store bottles in a cool, dark environment, away from direct sunlight and extreme temperatures. A pantry or basement is ideal.
- Avoid Heat: High temperatures accelerate the degradation of plastic and can increase chemical leaching. Never leave bottled water in a hot car.
- Keep Sealed: Ensure the cap is tightly sealed to prevent contamination and maintain freshness.
When Should You NOT Drink Expired Bottled Water?
While drinking water a year or two past its date is usually fine, there are situations where you should err on the side of caution:
- Visibly Damaged Bottles: If the bottle is cracked, bulging, or shows signs of significant wear and tear, discard it.
- Cloudy Water: If the water appears cloudy or discolored, it may be contaminated.
- Strong Odors: If the water has an unusual smell, do not drink it.
- Stored Improperly: If the water has been stored in direct sunlight or extreme heat for an extended period, it’s best to replace it.
Comparing Bottled Water Storage Options
| Storage Condition | Water Quality After 2 Years | Potential Risks | Recommendation |
|---|---|---|---|
| Cool, Dark Pantry | Good to Fair | Slight taste alteration, minimal leaching | Generally safe for consumption |
| Hot Car/Direct Sunlight | Poor | Significant taste change, increased leaching | Avoid consumption, replace the water |
| Refrigerator (Unopened) | Good | Minimal taste change, very low leaching risk | Good option for extending shelf life |
| Opened & Unrefrigerated | Poor | Bacterial growth, contamination | Discard immediately, do not consume |
People Also Ask
### Can I drink bottled water from 2015?
Drinking bottled water from 2015, which is over ten years past its typical expiration date, is generally not recommended. While the water itself may not be toxic, the plastic bottle would have significantly degraded. This could lead to a strong plastic taste and a higher likelihood of chemical leaching into the water, making it unpalatable and potentially less safe for consumption.
### Does bottled water expire if the seal is broken?
Yes, bottled water absolutely degrades if the seal is broken. Once opened, the water is exposed to airborne bacteria, dust, and other contaminants. It can also pick up odors from its surroundings. It’s best to consume opened bottled water within a few days, even if it’s not expired, and always refrigerate it.
### What is the safest way to store bottled water long-term?
The safest way to store bottled water long-term is in a cool, dark, and dry place, away from direct sunlight and extreme temperature fluctuations. Storing it upright in a pantry or basement is ideal. Avoid storing it in garages, sheds, or vehicles where temperatures can vary widely.
### Will drinking old bottled water make me sick?
It is highly unlikely that drinking old bottled water (a year or two past its expiration) will make you acutely sick. The primary concerns are taste degradation and potential leaching of chemicals from the plastic over time, which are generally considered low risks with occasional consumption. However, if
