The Many Uses of a Bar Spoon
Most people understand the basic function of a spoon, but when mixing drinks bar spoons are used in many different ways. Since some of those uses might be foreign to an aspiring mixologist, let’s look at a few:
 
Cocktail Stirring – Some cocktails need to be stirred not shaken, and the bar spoon is the perfect tool. Whether using a cocktail shaker or tall glass, the long handled spoon will make quick work of mixing any cocktail.
 
Measuring Ingredients – One bar spoon is more or less equivalent to one teaspoon and bartenders will use it to measure small quantities.
 
Layering Drinks – Mixologists interested in displaying an artistic flair use the flat bowl of the bar spoon to layer different spirits in one drink. Often used for shots like a B-52 or an Angel’s Kiss, the appearance is definitely striking.
 
Garnishing Drinks – As one of the one of the most useful bar tools, the spoon is often called upon to remove extra pulp from fruit garnishes.
