You'd be hard-pressed to find a more suitably named cocktail bartender than Brooklyn-based Ivy Mix (@ivymix). And not only for the obvious reason that the woman can make a drink. (Her favourite is the negroni: "It's a tough one to really mess up.") She also tends to mix her passions in what might at first appear to be dissonant ways. Nowhere is this more apparent than with Speed Rack, the all-female bartending competition and breast cancer charity that she co-founded with Lynnette Marrero in 2011.
