When my husband and I have Tanqueray we end up in war...when we have
Gilbey's - we don't!  I heard somewhere that Tanqueray glows green in
the dark.  What is that which 'glows' green in Tanqueray, and is that
our 'hostility' culprit?

Regarding the matter of Tanqueray glowing, I suspect that you may have
seen a gin-and-tonic that glowed under black light. It's not the gin
that's responsible: the tonic water contains quinine, which gives off
a glow when exposed to ultraviolet light.

I cannot offer a scientific explanation for Tanqueray producing more
fights than Gilbey's gin. But I have noticed that many people may
associate certain kinds of alcoholic beverages with experiences that
occurred when they were under the influence of that beverage. For
instance, many years ago I got terribly ill after drinking too much
Scotch. To this day, I feel queasy if I even smell Scotch. A
psychological linkage between Scotch and nausea has formed in my mind.
On the other hand, I once had a wonderful romantic experience while
drinking cold duck sparkling wine. Ever since then, a sip of cold duck
puts me in the mood for love every time.

Perhaps, just by coincidence, you and your husband had a disagreement
once while drinking Tanqueray. Thereafter, consuming Tanqueray may
have brought up unconscious connections with fighting and
unpleasantness, which may have led to the sort of mood that would be
conducive to another fight.

Just a theory. I doubt that you'll find any secret ingredient in
Tanqueray that causes fights. If there were such a thing, I would
imagine that pub owners everywhere would be reluctant to serve
Tanqueray to their customers, lest a brawl erupt. ;-)

What PinkFreud speculated makes perfect sense.  I don't know if she is
clinically correct but I certainly agree with her theory.  : )  Great
answer!!

Whatever additional ingredients may be found in Tanqueray,
we won't find them out easily:

"Although the Tanqueray gin is made with juniper berries,
 coriander, and angelica in the botanicals, the other
 ingredients remain a closely guarded secret. However,
 the Tanqueray gin distillery insists that the botanicals
 be added to the spirit immediately prior to the final
 distillation whereas some other gin distillers steep
 the ingredient in the spirit for a while before
 distillation occurs."

However, having spent 20 years in the field of mental
health, I'm inclined to agree with PinkFreud. While
unrelated to the Freud of psychiatric renown, PinkFreud
has identified the concept of association, which can
have such a powerful effect that some therapists
recommend that husbands and wives not look at each
other when arguing, lest they come to identify such
unpleasant feelings with the face of their loved ones.

Other than the mysterious ingredients, this may, indeed,
be the answer to your question.

The only other thought that comes to mind is whether 
you've looked at the bottle and noticed if the proof
of the Tanqueray you're imbibing has a higher proof
than the Gilbey's. There are some versions of Tanqueray
which are 94 proof, or 47% alcohol, as opposed to 
Gilbey's, which is 80 proof, or 40% alcohol, if I
remember correctly.

The only way to *really* test it, is to have someone else pour up the
drinks and see how you act when you don't know what the brand is.
