What device is used to control the pouring of liquor?

The pourer is designed specifically to control the flow of liquor when it is being dispensed from a bottle. Its construction usually includes a spout that helps regulate the pour rate, allowing bartenders to serve accurate measurements of spirits. By controlling the pouring speed and amount, pourers ensure consistency in drinks, which is crucial for both taste and cost management in a bar setting.

In contrast, a jigger, while also used for measuring, is not a device applied directly to the liquor bottle for pouring; it is a separate measuring tool. Strainers are utilized to separate solid particles from liquids, and shakers are used to mix ingredients, neither of which directly pour liquor from a bottle. Therefore, the pourer's specific technology and design make it the correct choice for controlling liquor dispensing.
