I don't. The - is only there to seperate the numbers from the words, if
the freezer was at a negative number, the - would be next to it; -33
degrees F as compared to - 33 degrees F.

 BF> About -4F (-20C) is enough.

I would assume that the temp of the beer/liquor would eventually reach
that, but not after 30 minutes. As it was, the cola was at a refrigerated
temp to begin with and probably had around 10 to 15 degrees to go before
freezing.

I wanted to eliminate the alcohol from the experiment and use an identical
liquid to find out if there was an affect imparted to the liquid by the
glass and/or aluminum can. There wasn't. So now we know that it's the
alcohol that is affecting the temp difference between the beer and liquor.

Yeup. The can will absorb heat faster than the glass will. BTW, make that
a frosted glass, the beer tastes much better than when it's in just a room
temp glass. :o)

Agreed.
