The secret behind the color of wine bottles

I wonder if everyone has the same question when tasting wine. What is the mystery behind green, brown, blue or even transparent and colorless wine bottles? Are the various colors related to the quality of the wine, or is it purely a way for wine merchants to attract consumption, or is it actually inseparable from the preservation of wine? This is really an interesting question. In order to answer everyone’s doubts, it is better to choose a day than to hit the sun. Today, let’s talk about the story behind the color of the wine bottle.

1. The color of the wine bottle is actually because “it can’t be made transparent”

In short, it is really an ancient technical problem! As far as the history of human craftsmanship is concerned, glass bottles began to be used in about the 17th century, but in fact, the glass wine bottles at the beginning were only “dark green”. The iron ions and other impurities in the raw material are removed, and the result… (And even the first window glass will have some green color!  
2. Colored wine bottles are light-proof as an accidental discovery

The early people actually realized the concept of fear of light in wine very late! If you’ve watched a lot of movies like The Lord of the Rings, A Song of Ice and Fire, or any of the European medieval movies, you know that earlier wines were served in pottery or metal vessels, although these vessels completely blocked Light, but their material itself will “deteriorate” the wine, because the wine in glass bottles is much better than other utensils for a long time, and the glass wine bottles at the beginning are originally colored , so the impact of light on the quality of wine, early humans really did not think so much!

However, strictly speaking, what wine is afraid of is not light, but the accelerated oxidation of ultraviolet rays in natural light; and it was not until people made “brown” wine bottles that they found that dark brown wine bottles were better than dark green wine bottles in this regard. Be aware of this! However, although the dark brown wine bottle has a better light blocking effect than dark green, the production cost of the brown wine bottle is higher (especially this technology matured during the two wars), so the green wine bottle is still widely used…
