Are plastic wine bottles OK?

Answered by Joseph Earl

As an expert sommelier and brewer, I have had the opportunity to work with various types of bottles, including plastic ones. Plastic wine bottles have gained popularity in recent years due to their convenience and lightweight nature. However, there are important considerations to take into account when it comes to the safety and quality of wine stored in plastic bottles.

One of the main concerns with plastic wine bottles is the presence of plasticizers. Plasticizers are chemicals added to plastics to make them more flexible and durable. These chemicals have the potential to leach into the wine, especially when it comes in contact with . Bisphenol-A (BPA) is a commonly used plasticizer that has been linked to several health problems, including hormone disruption and increased risk of certain cancers. While BPA has been banned in the production of baby bottles and sippy cups in many countries, it is still used in other plastic products, including some wine bottles.

The potential leaching of plasticizers into wine is a cause for concern, particularly for individuals who are more susceptible to the harmful effects of these chemicals. Pregnant women, children, and individuals with certain health conditions may be more vulnerable to the negative impacts of plasticizers. Therefore, it is important to be cautious when choosing plastic wine bottles and consider alternatives if you fall into one of these categories.

Another issue with plastic wine bottles is their permeability to air. Unlike glass bottles, which are impermeable to oxygen, some plastics can allow oxygen to enter the bottle. This can lead to oxidation of the wine, negatively affecting its flavor and aroma. Oxidation can result in a loss of freshness and vibrancy in the wine, making it less enjoyable to consume.

To mitigate the potential risks associated with plastic wine bottles, it is advisable to look for bottles that are specifically designed to be BPA-free. Many manufacturers now produce plastic wine bottles that are labeled as BPA-free, providing a safer option for storing wine. Additionally, opt for bottles that have a barrier layer or oxygen scavenging technology to prevent oxygen from entering the bottle and causing oxidation.

Personal experience has taught me that while plastic wine bottles can be convenient for outdoor events or picnics, they are not ideal for long-term storage or aging of wine. For short-term consumption, when the wine is not exposed to plastic for an extended period, the risks associated with plasticizers and oxidation are relatively low. However, if you are a wine enthusiast who enjoys collecting and aging wines, it is best to stick with traditional glass bottles to ensure the optimal preservation and aging potential of the wine.

While plastic wine bottles offer convenience and portability, there are potential risks associated with their use. The leaching of plasticizers, such as BPA, into the wine and the permeability of some plastics to oxygen can impact the safety and quality of the wine. It is important to consider these factors when choosing the appropriate wine bottle for your needs.
