Why do they put beer in dark bottles?
When hops in beer are exposed to strong light, a photooxidation reaction takes place, creating the compound 3-methyl-2-butene-1-thiol. To prevent the process of skunking from occurring, beer brewers have opted for darkly tinted glass. It’s why you see so many beers in brown glass bottles today.
Do beer bottles have to be dark?
Some glass suppliers apply clear, UV protected coats to glass to keep beer fresh, so the color of your bottle isn’t always an indication of its susceptibility to skunk. That said, knowing that light is an enemy of beer, it’s best to keep your bottles in a dark storage container to keep your beer from skunking.
Why is beer in brown and green bottles?
They eventually switched to brown bottles to block out the UV rays. After World War II, brown glass was in short supply so some brewers, especially in Europe, turned to green glass. You may be asking right now about the beer bottled in clear glass, because we do now have brands that use clear bottles.
Why are alcohol bottles dark?
Beer was stored in clear glass and when left in the sun for too long, it started to smell “skunky” – like a skunk, literally. This was because the clear glass allowed UV rays to penetrate the beer and alter the flavour. The solution was turning bottles brown, a darker colour which would block out the rays.

Why is Corona in a clear bottle?
The transparent bottle meant to show off Corona’s sunny yellow color is also the quickest way to “skunk” a beer, or oxidize it, letting light in that causes beer to lose hop flavor as well as produce off flavors.
What’s the difference between brown and green beer bottles?
Many companies were not able to get brown glass to manufacturer beer bottles and had to create bottles made of green glass. The green color did not protect as well as the brown but did a better job than clear glass. Beer producers started to use green glass to denote their higher quality beer.
Does beer go flat if not refrigerated?
Keeping beer at room temperature can drop a beer’s shelf life from nearly six months to only a few weeks, and exposing the same beer to very warm temperatures can affect its flavor in a matter of a couple of days. The good news? It can never make you sick. It just might not taste very good.
Can beer go cold to warm to cold?
It is a worldwide myth that somehow temperature cycling “skunks” beer. The truth is that temperature cycling has little to no effect on beer freshness. Think of it this way, if cold beer warming and then cooling again a single time ruined it, then all beer imported from Europe would be destroyed before you bought it.
Does beer really skunk?
But there’s bad news: Even though it’s cool and breezy out, your beer can still get skunked. Although many think that “skunking,” or the phenomenon of beer developing a putrid taste and smell, is caused by heat, it’s actually caused by light exposure.
Can you put beer back in the fridge?
So, the moral of the story is to keep your beer cold when you can, but don’t worry about beer warming up and then cooling again. It’s totally fine to drink it, and as long as it wasn’t kept warm for too long the flavor likely wasn’t changed.
