Tess Posthumus is a bartender, bar owner and freelance hospitality professional. She travels around the globe and owns two bars in Amsterdam: Flying Dutchmen Cocktails & Dutch Courage, where she and her team mixes the most delicious cocktails, while focussing on building a true cocktail culture in the Netherlands.

Tess Posthumus studied Media & Culture at the University of Amsterdam and completed her Sociology Masters in 2014. During her studies, Tess worked in the hospitality industry where she fell in love with the wonderful world of mixology. For eight years she worked at one of the best bars in the world: Door 74 in Amsterdam. Her talent hasn’t gone unnoticed, as Tess won several national and international competitions. She turned the side job into a professional career and travels around the world as a freelance hospitality professional.

In 2017 Tess opened her own cocktailbar together with Timo Janse, called Flying Dutchmen Cocktails. Here she and her team aim to build a true cocktail culture in the Netherlands by focussing on (neo-)classic cocktails while running an extensive education program for guests and the Dutch hospitality industry. In August 2020 her second bar opened its doors, Dutch Courage on the Zeedijk in Amsterdam. This new bar focuses on Dutch spirits and its heritage, with genever in particular. 

When she’s not running her bars, Tess is an in-demand hospitality consultant, is a member of the Tales of the Cocktail board of directors, (co-)owner of Perfect Serve Barshow Amsterdam and Amsterdam Cocktail Week. She wrote the two books ‘Cocktails with Tess’ & ‘Masterclass: Cocktails’, writes a monthly column for Drinks International magazine, owns her own set of ‘The Collection’ bar tools and her third book about genever will soon be published.

You can follow Tess’ adventures on her social accounts where she writes about her experiences, posts cocktail tutorials, and updates you on her genever research.
