A barback is a hospitality professional who assists the bartenders in restaurants, bars, or catered events. As a barback, your responsibilities and duties include preparing the bar before it opens, replenishing necessary supplies throughout the night, and helping break down the bar at closing. You are constantly on your feet, restocking glassware, alcohol, ice, and more. You also prep and restock garnishes and change out kegs. In between these other duties, you clean continually as bartending is messy work. Barbacking is a fast-paced and very physical job.
