Crap like this kills me. According to the article, beer drinkers have been
claiming this for years, but these two morons "found" it...kinda like
Columbus "discovered" America. I bet the Natives thanked their gods that he
came along and told them they were "there" huh?

Seems to me these two science geeks have WAY too much time on their hands,
and were looking for something--ANYTHING to get themselves published. This
is exacly the kind of "doctoral thesis" I'd love to get a Phd with. Can you
imagine defending this one before the board? What a gas! Oooo bad pun!


Prost from Milwaukee!

Re: Beer bubbles do sink to the bottom...

Can you think of a better study to do? I'll lay dollars that the beer
they used in the study didn't go to waist. :)

I thought they'd figured that out years ago? Something about the rising
bubbles in the middle of the glass creating an upward current in the beer
which then flows back down around the sides of the glass, carrying some
of the smaller bubbles down with it...?

By the way, I've only seen that effect in Guinness. Is it something that
is only visible in stouts? I'm still newbie level here...

Yes, i saw a story on that a few years ago on the dayly science news show on
Discovey Channel.

I imagine this works for all nitrogenated beers such as Guinness and
Caffrey's. The way I picture it is that as the bubbles break near the top,
the "unbubbled" beer needs someplace to go, and that is down. Then because
the N2 bubbles are smaller then regular CO2 bubbles, they are more tightly
packed together, and are more easily pushed down when the beer falls. This
may also work in reverse, that is, as the bubbles form near the bottom of
the glass and begin to rise, the N2 bubbles are packed so tightly together
that they carry some beer along with them toward the top of the glass.
That, at least, is my theory. Need more tests.
