The Green Green Glass of Rhône*

Most red wines are sold in colored bottles, and most of them are green.


Red wine in particular is light sensitive; the colored glass shields it from UV rays which tend to break down the antioxidants in the wine. Light attacks tannins and sulfites, and wine can go bad.

Now here's the kicker: If the reason for the colored glass is to protect the antioxidants from UV rays, then why are most bottles green if green only blocks about 50% of UV rays while amber glass blocks 90%?

Because they've always been green. Don't try to reason.
