Why do white wines favor glass and ceramic bottles?

Spirit, as an indispensable part of traditional Chinese culture and diet, is not only a regular guest at banquets, but also a bridge for emotional exchange. In the tasting of fine wine at the same time, it is not difficult to find, high-quality liquor often choose glass or ceramic bottles as its packaging, while those of poorer quality bulk wine often use plastic bottles. Why don't people choose plastic bottles for their liquor?

In the course of history, vintage wines were often stored in ceramic jars. Today, both ceramic and glass bottles are the preferred packaging for liquor. This is because it would undoubtedly be a poor understanding of liquor to put quality white wine in a plastic bottle. The main component of white wine is ethanol, which is commonly known as alcohol, it has a high volatility. The glass or ceramic bottle sealing performance is excellent, can effectively slow down the volatilization of ethanol, so that white wine can maintain its unique flavor for a long time. In addition, pure grain brewed liquor will become more mellow over time, and the stability of glass bottles and ceramic jars makes them ideal containers for long-term preservation of liquor.
The main component of glass and ceramics is silica, which is not easily dissolved in wine and therefore does not produce chemical reactions when mixed with white wine, ensuring the purity and stability of the wine.
In contrast, plastic bottles are mainly made of polyethylene, a material that dissolves easily in alcohol and may trigger a chemical reaction when it comes into contact with white wine, affecting the taste and quality of the wine. Long-term storage of white wine in plastic bottles, the polyethylene content of the plastic may gradually dissolve into the wine, which will not only destroy the flavor of white wine, but also potentially harmful to human health. In addition, modern plastic products are often added plasticizer, it is easy to dissolve in alcohol, posing a threat to human health.
Therefore, in order to maintain the pure taste of liquor and ensure the health of consumers, high-quality liquor is more inclined to use glass or ceramic bottles as packaging, and avoid the use of plastic bottles. Such a choice is not only a respect for the traditional brewing process, but also a reflection of the responsibility for the health of consumers.
