Why champage bottle is green in colour?

Champagne bottles are not typically green in color. They are most commonly clear glass, with some exceptions.

Here's a breakdown:

* Clear glass: This is the most common type of glass used for champagne bottles. It allows the color of the wine to be seen clearly.

* Green glass: While some champagne bottles might be green, it's not a standard practice. Green glass is more commonly used for beer bottles, as it helps protect the beer from UV light.

* Other colors: Champagne bottles can also come in other colors, such as amber or even black, but these are less common.

So, while you might see a few green champagne bottles out there, it's more likely that a champagne bottle will be clear, allowing you to appreciate the beautiful color of the wine inside.
