[Avodah] Yayin Mevushal

[Alan Rubin]

As I understand it, according to many authorities, if a non-Jew
handles yayin mevushal this does not render it non-Kosher. The grounds
for this ruling is that cooking would invalidate the wine for  avodah
zara.

I am wondering about the logic behind this. There is a link between
kiddush and libations in the temple. Wine that is invalid for libation
in the temple might, lechatchilah at least, be unsuitable for kiddush.

If pasteurising or otherwise heating wine is enough of a mevushal to
take away the problem of touching by a non-Jew shouldn't that also
render it unfit for kiddush?
