Abstract

A cap that can be used to seal a bottle containing a beverage, such as a home-brewed beverage. The cap contains a hole in the center of a top of the cap and a liner behind the hole, the liner having a slit or opening thereupon. The cap allows for excess gas, such as carbon dioxide, to exit the bottle, while preventing unwanted materials from entering the bottle.
