What Are Beer Bottle Tops Called?

Beer bottle tops are commonly known as “crown caps” or “crowns.” These caps are specifically designed to seal beer bottles and keep the contents fresh and carbonated. They have been in use since 1892 and are widely used on bottled beer worldwide. Here are some key points about beer bottle tops:

1. Crown caps: The term “crown caps” is derived from the crown-like shape of these bottle tops. They are made of metal, typically steel, and are crimped onto the neck of the beer bottle to create an airtight seal.

4. Crimping process: The crimping process involves using a specialized machine to apply pressure and secure the crown cap onto the bottle neck. This ensures a tight seal and prevents any leaks or contamination.

5. Openers: To remove crown caps, various types of bottle openers can be used, such as traditional bottle openers, wall-mounted openers, or even innovative openers like keychain openers or magnetic openers.

6. Collectibility: Crown caps are often collected by enthusiasts known as “crown collectors” or “crowners.” Collecting crown caps has become a popular hobby, with some collectors seeking rare or unique designs from different breweries around the world.

7. Branding and customization: Crown caps can be customized with different colors, logos, and designs, allowing breweries to promote their brand or create limited-edition bottle tops for special occasions or events.
