I hadn't realized this until just now, but most good beer comes in brown bottles. It is only beer that is sold by marketing rather than taste that comes in different-colored bottles. (I'm looking at you, Corona, Dos Equis, etc.)
So I think that even before this paper, brewers realized that beer in brown bottles keeps better.
I actually like Corona, though I consider it more to be brand of lemonade than a brand of beer. But yeah, real beer goes in brown bottles. There's no questioning that.
Disclosure: my national identity allows me to say anything I want about beer and be right on principle.
This is good advice if you're going to bottle your home brew. I much prefer kegging. Sanitizing + bottling 50-60 bottles is a huge pain.
Now that I think of it, I don't think my local homebrew supply even sells non-brown bottles.
