Frankie Solarik and Julie Reiner serve as sippers-in-chief on the series. Frankie is the author of The Bar Chef: A Modern Approach to Cocktails. He also sells a line of bottled drinks — which are based on drinks from his own world-class bar in Toronto, Canada — to encourage folks to enjoy quality cocktails at home. Frankie's bar was hailed by Condé Nast Traveler as “living up to” its “lofty ambitions” and a must-visit for anyone interested in the “global cocktail scene.”

As for Julie, according to her website, she is a mixologist, author, and consultant based in New York City. Her tome is titled The Craft Cocktail Party: Delicious Drinks for Every Occasion. The esteemed establishments Julie owns — Clover Club and Leyenda — are located in Brooklyn. New York Magazine called Clover Club "one of the best drink destinations in the entire city." Like her fellow Drink Masters judge, Julie sells a line of cocktails. Hers are canned and are called Social Hour Cocktails.

Although she’s clearly the perfect fit for the role of being one of the Drink Masters judges, Julie admitted at first she wasn’t sure she wanted to be on TV. In a post on Instagram, the new reality star said, “Putting yourself out there publicly isn’t easy. In the end, It was a great experience.” For his part, Frankie said in part on his own Instagram that it was an “honor” to be on the Netflix show.
