Katie Renshaw


Katie is a bartender in Chicago, where her passion for cocktails drove her to leave her “day job” to seek mentorship behind the bar; to her parents dismay, she never looked back. She’s bartended at some of Chicago’s top bars including Moneygun, Drumbar, GreenRiver, and Billy Sunday. She has also seen success in several bartending competitions, as the midwest winner of Speed Rack, national finalist for Heaven Hill Bartender of the Year, Italicus Bar Artist of the Year 2018, and most notably, winning the title of 2019 US World Class Bartender of the Year.

Katie’s creativity, cocktail nerdiness, and attention to detail bring life to High Proof’s digital content and cocktail classes.
