Lol, that made me laugh. I did think of that, but I didn't think anyone.. No never mind
That's a better question. It would really depend on a number of different factors, such as the temperature of the bottle and the environment (snow can be colder or warmer than the air temperature, as it changes temperature more slowly), and the size of the bottle, even what the bottle is made of if one wanted to get technical. But in the situation you outlined, the snow would cool it pretty quickly. At room temperature the bottle/liquid would have very little thermal energy, and can't generate more, its mass is very small/area through which heat can flow large, and it is in direct contact with the snow. The situation kind of voids the insulation capability/capacity of snow.
