(Part 3 in a series - The Value of Glass)

Beer, wine and whiskey in plastic bottles? Not so much. Alcohol
trumps plastic in the glass-plastic-alcohol game. Oxygen and chemicals
and tend to leach into alcoholic liquid when it’s in plastic resulting
in shorter shelf life and ruined products, a factor that is not an
issue with glass containers.

“Glass is inert,” reminds Joe Cattaneo, President of the Glass Packaging Institute. “Glass doesn’t react to chemicals. Glass presents the true flavor of the product, preserves its purity and quality, and increases shelf life.”

Not that PET beer bottles are non-existent. MillerCoors
started bottling in PET since 1998 for use in stadiums and other
outdoor sport events. In October they reported use of plastic bottles
is now at 10 percent. On the issue of health and PET alcohol
containers, the New York Times reported on November 28 that PET bottles
were safe as containers for alcohol according to conclusions by Food
and Drug Administration.

Let’s try it again

Between
1969 and 1973, some alcoholic beverages were packaged in polyvinyl
chloride (PVC) bottles, but that gig came to an end as PVC was strongly
suspected as a carcinogen while in the company of alcohol. PET,
on the other hand, although it has also been charged as a possible
health threat, has recently been acquitted and given the green light as
alcohol containers.

Nevertheless, PET alone is not sufficient to protect the product from oxygen ruin, altering the taste and quality. An additional barrier must be added to the container by lining the inside to prevent deterioration of the contents. The consequence is that the multi-layer design interferes with normal PET recycling process.

Glass still looks best as an entirely recyclable commodity with no health issues. Now
when I asked Hazel Mobley the glass specialist in Atlanta about the
manufacturers that buy cullet, she mentioned several large well know
glass companies then she skipped to another thought.

“Didn’t you say you’re headed north through Tennessee?” Indeed, yes. “You know, you ought to take the tour of Jack Daniel’s distillery in Lynchburg. Now that’s one retailer I know that’s really particular.”

Well, aw-raaat! I don’t drink, but I’m up for checking on Jack
Daniel, where apparently everything matters, including glass. I’ll tell you about it tomorrow.
