Ugh. You guys are getting medieval on me.
Thanks for all the ideas.
I did a test on waxing cork with red candel wax.
By heating BOTH cork and wax well above melting point
I had expected perhaps a millimeter of penitration
like soft wood. Nope, no visible penitration, but
I got good bonding with the waxy feel impossible to
scrape off. Unexpectedly, the wax was drawn into
and sealed the hairline fractures caused by the
corkscrew, at least 1/4 inch deep. (I used binoculars
as a microscope.)
Thoughts on that? Possibilities maybe?
Here's more thoughts from the web.

Alternative wine closures - Wikipedia, the free encyclopedia
Alternative wine closures are substitutes used in the wine
industry for sealing wine bottles in place of traditional cork
closures. ...A 2007 study by Victor Segalen Bordeaux 2 University
showed that synthetic cork allowed the highest levels of oxygen
permeation in when compared to natural cork and screw caps,...
Screw caps form a tighter seal and can keep out oxygen for a
longer time than cork. These benefits aid in maintaining the
wine's overall quality and aging potential....
"consumers still perceive screwcaps as being for ‘cheap’ wines
(regardless of the price tag)."...
European market (under the name Vino-Lok) in 2003, over
300 wineries have utilized Vino-Seal. Using a glass stopper with
an inert o-ring, the Vino-Seal creates a hermetic seal that
prevents oxidation and TCA contamination. A disadvantage with the
Vino-Seal is the relatively high cost of each plug (70 cents
each) and cost of manual bottling....

.. Although easier to open, crown caps eliminate part of the
ceremony and mystique of opening a sparkling wine.
There is continuing opposition to the use of
alternative closures in some parts of the winemaking industry. In
March 2006, the Spanish government outlawed the use of
alternative wine closures in 11 of Spain's wine producing regions
as part of their (Denominacion de Origen) D.O. regulations. [18]

Wine fault - Wikipedia, the free encyclopedia
Cork taint is a wine fault mostly attributed to the compound
2,4,6-trichloroanisole (TCA), although other compounds such as
guaiacol, geosmin, ... Anthocyanins, catechins, epicatechins and
other phenols present in wine are those most easily oxidised [1],
which leads to a loss of colour, flavour and aroma - sometimes
referred to as flattening.

Stelvin cap - Wikipedia, the free encyclopedia
A metal screw-cap developed by the Alcan Packaging company to
replace wine corks to reduce the occurrence of cork tainting. It
also incorporates a small ventilation system to allow tiny
amounts of air into the wine bottle to aid the wine maturation.
The reluctance over the adoption of this cap seems to be the
brand degradation caused by using a screw-cap on a wine.

Screwcap - Wikipedia, the free encyclopedia
A screwcap is a type of alternative wine closure that is gaining
increasing support as an alternative to cork for sealing wine
bottles. ... Traditionally associated in the US with extremely
inexpensive jug wines or even "skid row" wines, the screwcap is
making a comeback due to concern about premature (or sporadic)
oxidation and cork taint. Screwcaps have a much lower failure
rate than cork, and in theory will allow a wine to reach the
customer in perfect condition, with a minimum of bottle
variation. Cork, of course, has a centuries-old tradition behind
it, and there are also concerns about the impact of screwcaps on
the aging of those few wines that require decades to be at their
best.
Some argue that the slow ingress of oxygen plays a vital
role in aging a wine, while others argue that this amount is
almost zero in a sound cork and that any admitted oxygen is
harmful. Various studies are underway,

Bottle variation is the degree to which different bottles,
nominally of the same wine, taste and smell different.
Bottles stored together their entire lives, with no obvious
faults, can taste completely different. Thus there is a saying,
"There are no great old wines, only great bottles."
