Like a box of fine china or a man covered in ants, cocktails just beg to be shaken. Learn how to stir up the nightlife with today's Groupon: for $160, you get a state-licensed bartending course at Eastcoast School of Bartending in Chester (a $395 value). Courses typically last for 40 hours; the next session starts Monday, December 5. Courses are available on days, nights, weekends, and custom schedules based on need and availability.

At the Eastcoast School of Bartending, students soak up cocktail-crafting skills and practical service-industry knowledge during classes with certified instructors. Classes cover every aspect of professional bartending, from practical subjects including drink recipes and preparation techniques to philosophical topics such as whether a whiskey neat should be served half-full or half-empty. Novices sling drinks from behind fully operational stations to balance customer-service skills with confident use of the fountain gun, cocktail shakers, and other standard tools. Upon completion, students receive a graduation license approved by the New Jersey Department of Education, recognized in all 50 states with no renewal needed, as well as lifetime access to the school’s complimentary refresher training and job-placement services to find a gig shaking liquids at a local restaurant or as a part-time centrifuge.

In most states, you must be 18 years of age to legally bartend.
