It’s completely appropriate that bartending is also known as the art and science of mixology. As a bartender, you need to know who to mix and measure not only a jigger, or shot, but how much to add when a recipe calls for a dash of bitters or how many bottles of wine to send out when a customer orders a jeroboam.
