At ABC Bartending School, burgeoning mixologists learn to mix, stir, and shake a variety of classic and modern libations under the tutelage of experienced instructors. During the amateur bartending course, students learn the basics of alcoholic alchemy, blending liquors and mixers into sippable sensations over the course of two knowledge-soaked hours. Bartenders-to-be also receive extensive instruction and hands-on practice with tools of the trade such as shakers, blenders, and Maraschino-cherry trees. Classes of 12 or fewer students are held on Fridays from 5 p.m. to 7 p.m. as well as Saturdays from 1:30 p.m. to 3:30 p.m. or 4 p.m. to 6 p.m., to ready cocktail crafters for in-home parties after stressful Rubik's cube competitions.
