What does the color of a wine bottle relate to?

Among many wine bottles, green is the most common color, which is actually related to the limitations of early glass manufacturing technology.

In the 17th century, when wine bottles had just appeared, the raw materials used for glass production contained iron-containing compounds to a greater or lesser extent. The technology at that time could not remove these impurities, so the wine bottles turned green.

However, such colored wine bottles can effectively reduce the impact of ultraviolet rays on wine and avoid photo-oxidation of wine. This green wine bottle has been used to this day.

Transparent glass bottles always give people a fresh and translucent feeling, and can most directly display the attractive colors of wine in front of consumers. Therefore, many white wines and rosé wines are often filled in transparent glass bottles.

However, this kind of glass bottle is only suitable for bottling wine that will be consumed within one to two years, otherwise it will be easily oxidized. Generally, wines that need to be aged will be placed in colored glass bottles, but this does not mean that wines in colored glass bottles have a long aging potential.

With the development of glass technology, brown, amber, and blue wine bottles have also appeared on the market. This is mostly related to the habits of the production areas and marketing methods.
