How cold is it? If it isn't water in the bottle , then that's sufficiently frigid to congeal the nether parts of the brazen image of a simian! [Hope you treat your single malt better!]
Reminds me of delivering mail in Toronto back in the early '80s. 38 degrees below [pretty much the same in F or C] and I-have-no-idea-what-the-****-the wind-chill-was...... My hands throb when I think of it.
Had to chuckle. This morning it actually snowed in Vancouver. That's three times this 'winter' [depending on what part of town.]
