What is a beer cozy and why do I need one?

A cozy (or koozie or cosy depending on where you are from and how you want to spell it) refers to a piece of foam (or in this case crochet) that wraps around your beer bottle to keep it cold. It's also know at a beer jacket or beer huggie. They can be rigid or soft and flexible or even slide onto cans and cups. And they’re everywhere! They are often used as marketing tools with business names and logos slapped to the sides.

The origin of the beer cozy is surrounded in myth and folklore, just like the leprechaun who's hat takes the form of one in this tutorial.

Some say the beer cozy was invented in Australia in the 1970's, others say it's origins are rooted in England where knit cozies were used on bottles to keep their contents ice cold.

Despite the myths and legends, here is what we do know for sure:

The Radio Cap Corporation registered a trademark for the name “koozie” in 1980. Just a year later, a woman named Bonnie McGough filed a patent for an “insulated drink cozy” with insulating material sandwiched by outer fabric. She suggested goose down as the insulator. And there you have it, the rest is history.
