Beer Bottle Bubbles.
StarChaser Tyger
reading posts before I go to bed, and picked up an ex-beer. Happened to
cross the white screen in such a way that I noticed the two circular
marks, opposite each other.
About 3/8" of an inch across, centered opposite each other, equidistant
from the straight mold seams on either side. My first thought was that
they were mold lines of some sort, but why would it show as a perfectly
filled circle with just a small ridge around the edge?
Any idea what these are? It's on a bottle of Amber Bock, if it makes a
difference. I haven't seen them on clear bottles.

I assume the bottles are made with vacuum molding. Each half of the
mold would thus have a (circular) hole in it, where the vacuum line
sucks the air out.

bottle is made. In plastic molding these would appear on the body of
the pre-form and I would expect them to disappear on the final blow
molding step. I will empty a Yuengling Black & Tan tonight and
investigate.

Heh. Two answers; one sucks, one blows. I thought of the injection too,
but why don't clear bottles seem to have it, and why is it perfectly
flat, just has a ridge around the edge? If it was created by sucking air
out, one would think it would bulge a bit...

I was thinking of plastic bottles. Glass isn't vacuum molded that I
know of.
Answer to your question: because they grind off the flash after the
thing cools.

The answer mentioning vacuum molding of the glass bottle is wrong. Glass
bottles like your beer bottle are blow molded. A "gob" of glass is
automatically dropped into a mold and a small puff of air blows the glass down
to settle into the mold. Air is then blown into the mold from below and a
crude bottle shape is created. This crude glass shape is then removed from the
mold and inserted into a second mold that is the shape of the final bottle. Air
is blown in from above to form the final shape. The machinery that performs
all of the operations is mind-boggling to watch, particularly how the molten
gobs of glass are delivered to the mold.
Re the circular thingy on your beer bottle, it is *probably* from a "slug" that
has been removed, and the mold has been reworked. A slug is a design, or name,
or emblem that is inserted into and made part of the mold, and that
manufacturers name or design becomes molded into the bottle. Molds are *very*
expensive, and if someone had a special mold made but is no longer a customer,
then the mold is salvaged as much as possible. Those perfect circles may have
had a specific design that was removed.

Data point: beer bottles used by all major breweries are
interchangeable. The idea was to facilitate returns. You can (or
rather the distributor can) return Miller bottles to Anheuser-Busch,
and they clean them, put their own labels on them, and Voila!
This means that none of the majors can or does put any markings on
the glass itself.

They don't look so interchangeable to me.

It's entirely possible that the molds described may have originally been used,
with a slug insert, for something like:

They are beer bottles.

So Miller has stopped using clear bottles?

Some aren't majors, and some I believe are no longer used.
I've been at four Miller breweries, and I promise, they used standard
bottles.

bottles are made the way you describe. The preform is called a
paraison(sp?)which looks sort of like a thick walled test tube. It
then goes into another mold cavity where it is heated and pressurized.
This stretches it and forces it against the cavity wall to the final
shape.
Presumably a similar thing is done for glass bottles.
My brown Yuengling B&T bottles have a pair of opposed circular marks
at the shoulder, 90 degrees out from the parting lines. If it was a
plastic mold I would say these were ejector pins, designed to force
the part out of the mold after the blowing cycle.
I will have to force myself to get a case of Corona and see if clear
bottles have the same mark.

But the flash is still there. The thing I'm talking about is a ring of
slightly raised glass around an otherwise unremarkable area.

Possible, I guess, but this is a Michelob Amber Bock bottle. Is
Anheuser-Busch likely to use bottles made by someone else? <I don't
know, I'm asking.>

Hmmmmm. That just seems really wrong, doesn't it? Miller in brown?

Anheuser Busch does not make all its own bottles.

MGB. The "High Life" is still in those clear, distinctive bottles
(and is a superior beer, IMHO).

To MGD, sure, why not? But in general? Miller is a quality beer (in
that they keep producing something that tastes the same wherever and
whenever it gets brewed) but it's not a superior beer.

No, although at one point there was some truth to this, it hasn't been terribly
true for some time in most markets. It is much more the case that a bud
longneck and a bud lite longneck might match, and those bottles may be
recycled, but at the moment A-B is the only brewer I know that is recycling
their bottles at all.
Most breweries have switched to thinner more fragile non-returnable bottles,
that weighing half as much, cost half as much to ship, not to mention the
influx of plastic that certainly doesn't seem to hold back the consumers of
american piss waters any.

Of course, Joe. I was merely comparing High Life to MGB. High Life
is "better" than MGB. No comparison with real beer is necessarily
implied here.

Is that because you like Miller beer, or just some twisted

This used to be true here, but fell apart about 1990.
In the early eighties, allmost all non-heinekin beer sold here was in
identical short wide bottles. A few "premium" companies started using
long-neck bottles. I believe that there was a large sorting fee
applied by the local liquor-control board (which includes all alcohol
sales) to get these custom bottles back to the original owners.
Eventually, only the discount beers were sold in the "stubbies", and
soon after that, the sorting fee was added to the no-longer-standard
stubbies. Without the cash savings from a standardized bottle, most
of the deep discount brands switched to aluminum cans.

It's because I used to work for a company that made brewery
equipment. I was there training their packaging crews to use the
system.
I don't like Miller. I don't like *beer*, in fact -- I've never
liked bitter flavors.
