Men in suspenders with ironic mustaches no longer define the star mixologist; talented women are on the rise. Some of the credit goes to Marrero and Mix, the duo behind the all-female bartending competition and networking confab Speed Rack. Now in its fourth year, it has raised $300,000 for breast cancer charities and is expanding in scope and influence, driven by what Mix calls its “girl-power notions”: It recently hosted a summit—a series of demos organized around the Speed Rack Finals—as well as competitions abroad. As the company grows, Marrero and Mix are thinking globally. “We’re constantly contacted by people from different countries, asking us to bring Speed Rack to their communities,” says Marrero.
