For 22 years, the Oklahoma School of Bartenders has instructed up-and-coming mixologists in the art of pouring drinks and managing the masses. The school’s classroom mimics a real bar, with shelves of liquor, vital tools, and three guys trying to beat the record on Deer Hunter at pupils’ disposal. Students get behind the bar to practice shaking and stirring under the careful supervision of teachers, all of whom have been training bartenders since 1988. Afterward, a job-placement program helps newly certified students land drink-slinging positions.
