Which shaker type is also known as a three-piece shaker?

The three-piece shaker, commonly known as the Cobbler shaker, consists of three components: a metal shaker cup, a strainer, and a cap. This design is particularly advantageous for bartenders because it simplifies the shaking process and eliminates the need for a separate strainer. The built-in strainer allows for easy pouring without any additional tools, making it a popular choice for creating cocktails that require shaking.

In contrast, the Boston shaker, composed of two pieces—a metal tin and a glass or another tin—requires a separate strainer for pouring, adding an extra step to the process. The Parisian shaker combines the features of both the Cobbler and Boston shakers, but it isn’t as common in use. Electric shakers are powered devices that create mixes through mechanical means, which is a completely different approach from the traditional hand-shaking methods. This distinction highlights the unique characteristics of the Cobbler shaker and its suitability for bartending tasks.
