My DH and I were just sitting here talking about thanksgiving and I can't
even remember how we got to talking about alcohol--but he said that he'd
just seen where some company (he couldn't remember which) said that they
were making a grooved beer bottle and he didn't understand why.  I told him
about the little white dingy thing inside that expensive Guinness beer.
 
When I bought it for the heart worm prevention, the first bottle I picked up
rattled.  I thought there must have been broken glass inside, so set it
aside and picked up another bottle, which also rattled!  I opened it and
poured it out and this little white thing was in the bottle.
 
So I googled and came up with the fact that they put those white things in
there to 'aerate and mix' the beer for 'better flavor' when you drink it.  I
told him I would imagine that whatever company it was would just put
straight grooves inside the bottle, and I wished it would be spiral groves
as that would give a vortex.  Those bottles would be great to have.
 
Suddenly I thought I'd Google for grooves in glass beer bottles and this
came up! I'm looking for some to buy when I go downtown!
