Stubby holders PROVEN to keep your beer cold: Science says so

Any regular stubby holder user will know that it keeps your brew colder for longer, but maybe you don't know the reason why?

Finally, in a productive use of research grant dollars, University of Washingston climate scientists have proven that stubby holders (known in the US as koozies) actually DO keep your beer cold.

According to the research, it is the actually the condensation that forms on the beer can or bottle that draws in the heat from the outside, warming your favourite beverage. Interestingly, it was proven that humidity is the major contributor rather than air temperature.

Stubby holders prevent the formation of this condensation on the outside of the container, keeping your beer colder for longer.

Inside Science interviewed the scientists about the research.
