Mary Pellettieri’s brewing and beverage industry career spans more than two decades. She served as chemist and microbiologist at the Siebel Institute brewing school in Chicago, where she also taught Sensory Management. Later she managed the quality program for Chicago’s young, independent Goose Island Beer Company in 2000. Her background and experience made her a desirable judge at prestigious beer competitions and later as quality manager for the historic MillerCoors Milwaukee brewery. Pellettieri speaks nationally on a variety of topics in quality, sensory analysis and brewing science, including at Craft Brewers Conference & BrewExpo America®, AHA National Homebrewers Conference, American Society for Quality, and Master Brewers Association of the Americas. In 2014, Pellettieri started her own beverage consulting service and company. She makes her own beverage concentrates, contract produces elixirs for the spirits industry, and consults with large and small beer, wine and cider companies. In 2017, Pellettieri was selected as the first-ever Brewers Association Quality Instructor.
