Answers.Text: Interesting about the UV protected coats. I wonder if this applies to clear growlers as well (yes, I've seen clear growlers, and yes I've had beer in them skunk rather quickly).

Answers.Text: Well, certainly, a brown UV-coated bottle must still outperform a clear UV-coated bottle? Good question though, I don't know.

Answers.Body: <p>I would expect that companies which use clear bottles don't expect their product to see that much sunlight, or that they think their customers won't notice a little skunking if it does see any.  Anecdotally, I typically associate clear bottles with the larger brewers (Coors, Budweiser), and I don't think of those beers as having much in the way of hops, the source of the isohumulones which, when combined with light, create the "skunk".</p>

Answers.Text: you can spot the hop extract without isohumulones by the incredibly rocky head it produces. It's a little unusual.

  <p>But why do breweries continue to use green and (especially) clear bottles? Why bother with a bottle that is more likely to allow beer to spoil?</p>

  So, perhaps it's no longer the case that clear and green bottles are (noticeably) inferior to brown bottles!
