MISSOULA, Mont. -

As the weather heats up, one Missoula bar has a new way for you to keep that drink cold.

It's called a frost rail which is a piece of chilled steel that runs the length of the bar. It’s for people to rest their drinks on.

The Rhino bar downtown, is the first and only Missoula bar to have one.

Co-owner Brad Martens says he keeps it at 32 degrees.

"With having 50 beers on tap here, it just made sense to me that why not have, or since we were redoing the bar, why not take the opportunity to put in something that will keep your beer cold," said Martens.

The frost rail was designed and made by Martens and three friends. Together they brainstormed and developed how it would work. The rail is mostly made of aluminum and stainless steel.
