Clear glass bottles

[MickDundee]

Best not sit in a beer garden next summer then.

I must invent a beer glass like the takeaway coffee cups to stop beer getting skunked in a beer garden. Do you reckon any of the Dragons would invest?

Drink halves in summer. It could be an urban myth but I've heard skunking is why stubbies are popular in Australia.

Quite possibly. I've quite often seen the assertion that skunking can take minutes.

None of these links are from scientific sources, they are just ramblings from sensationalist journalists. Scroll to the bottom of the popsci.com link, to where they proclaim that "Yes, monkeys are having sex with deer. Why would they do that?" then watch the video of a couple of monkeys wiping their arses on deer. No science there then, just itchy arsed monkeys.
You may be good at googling, but there's no scientific basis of any of your copy and paste "scientific" articles.

The article clearly states that the monkeys (and, more surprisingly, the deer) get sexual pleasure from the monkeys rubbing their buttocks on the deer. But this might be off topic.

Ffs I've had nothing but grief for posting scientific resources. [emoji23]

Yes, admittedly they were a quick Google, prior to going to play football. Sorry. Feel free to ignore, or do deeper research. Although you didn't ask for scientific articles, just who are they? that are saying light strike happens quite quickly.

Hi!
Isn't one of the issues with beer tasting the fact that it is subjective? There are some who can detect dicetyl in a beer that others would find acceptable.
There is sufficient anecdotal evidence that beer in the glass in full sun will become light struck very quickly - a matter of minutes, if not seconds.
Some brewers have used green bottles in the past to distinguish their premium beer from their standard brew, and continue to do so even though there is no real advantage over clear glass.
Brown bottles seem to be the norm - I don't store them in full sun but I don't worry about keeping them in total darkness.

Bang on, totally agree. I think I said pretty much the same, earlier.

Stumpies are popular in Australia because beer is $12 a pint:-o

I always thought that was so the got finished before they got to warm

If you want a properly scientific look at how beer becomes lightstruck try here, and the article does say it can happen very quickly:

If you drink your beer from a pint glass on a sunny patio you may notice this flavor by the time you reach the bottom of the glass – that’s how quick this problem can arise.

And I am certain I've experienced this drinking a commercial lager in the sun.

Hi!
Any scientific advice about types of UV light that causes beer to become lightstruck?
If you are indoors the glass in the windows absorbs UV(B) but not UV(A).
Will keeping beer indoors leave it open to "skunking"?

UV(B) causes it when it breaks down isomerised alpha acids, but unfortunately keeping it indoors won't prevent it because low wavelength visible light can also cause it through a slightly different mechanism.

I agree, and not just lagers either. I love a bitter beer and I'm certain that the last part of the glass is noticeably less bitter and doesn't have the flavour of when it's fresh out of the pump and I'm sure it's not just the sun warming it up.

Hi!
So keeping beer in the dark, so to speak, is best for it? I assume a dim light won't be too bad.

low wavelength visible light

longer wavelength visible light?

Yep, less light the better really. Even the reduced hop extract that Miller uses is degraded by light, the difference is though that it doesn't form the skunk compound afterwards.

Low wavelength visible light is science speak for blue light

Good, now I can explain the missus why I prefer to drink in the dark.
Sunlight==bad. Dark==good.
