Knowledge of wine bottles

What are the materials of wine bottles?

The main materials of red wine bottles are as follows:

Glass: This is the most common material for wine bottles. Glass has good chemical stability, does not react with red wine, and can maintain the quality of red wine well. Its transparent characteristics allow people to intuitively appreciate the color of the red wine. The glass material can also provide better barrier property to prevent oxygen from entering the wine.

Crystal: Some high-end wine bottles will use crystal material. Crystal bottles are more exquisite and have a higher refractive index, which can make red wine look brighter. But the cost is relatively high.

In addition, in some special cases, there may be some other materials of wine bottles appear, but more rare. For example, some bottles made of environmentally friendly materials, or some experimental new materials. However, glass is still the mainstream material of the current wine bottle.

What are the differences between a glass wine bottle and a crystal wine bottle?

Glass wine bottles and crystal wine bottles have the following differences:

Appearance texture: crystal wine bottles usually have a higher refractive index and gloss, looking more crystal clear, bright and gorgeous, more ornamental; Glass wine bottles are relatively common.

Weight: Generally speaking, crystal wine bottles will be heavier and have more texture in the hand.

Sound: When tapped, the sound of the crystal wine bottle is more crisp and pleasant, while the sound of the glass wine bottle is relatively dull.

Cost: Because of the complexity of the material and process, the cost of crystal wine bottles is often much higher than that of glass wine bottles.

Process difficulty: The process requirements for making crystal wine bottles are usually more stringent and difficult.

Collection value: Some high-end crystal wine bottles may have a higher collection value because of their uniqueness and delicacy, while glass wine bottles are relatively weak in this respect.
