Mixology the mixing of liquids to create cocktails can be classified as both an art and a science. The act of combining specific amounts of alcohol and mixers such as water soda juice or milk products is a science that allows a bartender or a restaurant owner to maintain consistency in their drinks. Using standard amounts also allows the bartender to come up with new drinks that can be reproduced easily by others. The art of mixology is expressed in the drink presentation and the bartender flair at showmanship and entertainment.
