Screw Cap- The best thing to happen to wine?

Over the last few years I am sure you have seen many of your
favorite wines go to a screw cap or Stelvin closure. Why you ask? Primarily, it
is because this may be the only true alternative to ridding the wine industry
of cork taint.
In a short explanation it is presumed to be the cork that
inhibits the flavors in some of the World’s best wines. The scientists tell us
that cork taint is mainly due to the compound 2,4,6-trichloroanisole (TCA).
This compound is found in bad corks and results in wines that have mouldy or
musty aromas. Wine lovers who are familiar with cork taint can detect it right
away and generally feel that this wine is ruined, and return the wine for
another bottle. Some consumers, though, who are not familiar with cork taint
just believe that the wine is “bad” and they will never buy that wine again.
That is unfortunate because had these consumers tried the same bottle of wine without
the bad cork, they may actually have loved it. This can cripple a wine
producer, as the “word of mouth” spreads the belief that the wine is “bad”,
ruining a reputation that they have worked so hard to establish.
The percentage of wines ruined by taint range anywhere from
2-10%. Can you imagine any other industry in the world that could survive if
10% of the products they produced were defective? What if 10% of the products the automobile
industry produced were defective? How about the Airplane manufacturers? Scary……
In addition to preventing the TCA to inhibit the wine,
Stelvin closures also make the wine; easier to store (they can be on their
side, standing straight up or upside down in your cellar), free of leaky corks,
more fruity due to better preservation of the flavors.
It is important to know that cork is a natural product
harvested from the bark of a tree. This bark contains bacteria, which is common
for most living things in nature. The cork producers attempt to kill all the
bacteria before production, but some survive. Now imagine if you put this bacteria
in a bottle full of yeast and decomposing fruit juice, it will thrive in this
environment. The sanitized stainless steel “screw cap” seems like a pretty good
alternative now, doesn’t it?
So next time you are shopping for wine and see a Stelvin
closure, don’t turn your nose up with images of
Mad Dog 20/20 or Boone’s Farm. Give it a try, it is the best closure
option, in this wine guy’s opinion.
Cheers,
