American Wine School, Cleveland

Grape guru and oenophile Marianne Frantz, who holds a diploma from London's Wine & Spirit Education Trust (WSET) and who earned an Advanced Sommelier qualification from the Court of Master Sommeliers, founded American Wine School in 2002. She and her school have gone on to shepherd more than 10,000 sippers through classes, tastings, and grape-lookalike contests. Marianne, along with her knowledgeable staff, impart their vino wisdom in classes that range from the basic Wine 101 to the more extensive WSET certification courses. The school's classes and special events have even spilled into seven different states, teaching tongues across the nation to swirl, sniff, and taste the adult beverages and analyze why drinking wine while doing taxes is a bad idea.
