Generally speaking, most red wine bottles are made of glass, because glass has the following advantages:

1, high transparency: glass bottles can clearly show the color and texture of wine, so that consumers can intuitively understand the characteristics of products.

2. Good sealing: the bottle mouth can be sealed with a plug or a metal cover, which can effectively prevent the leakage of wine liquid and the entry of oxygen, and is conducive to maintaining the freshness and quality of wine.

3. Good chemical resistance: the glass bottle will not react chemically with the wine and will not change the taste and quality of the wine.

4. Strong recyclability: glass bottles are recyclable and environmentally friendly.
