The Necks On Beer And Soda Bottles Serve A Purpose
The neck on a bottle of beer or a glass soda bottle was designed for a very specific purpose. Manufacturers wanted to make sure their beverages would stay cold for as long as possible.
The long design shape with a narrow top was created specifically so patrons will hold the top of the bottom where the least amount of beverage is stored. This helps avoid the beverage from warming up too quickly and ruining the taste.
