Riezenman has taught, cooked, consulted and hosted in Italy, Hong Kong, Thailand, throughout Canada and the US for organizations that include Certified Angus, Cattlemen’s Beef Association, Darden’s Restaurant Group, Starbucks and others. Chef Riezenman has presented at the Boston Wine Expo and has been a guest chef three times at the prestigious James Beard House in NYC.

Bruce’s career began at the Culinary Institute of America in Hyde Park, NY where he graduated in 1979 with high honors, after previously majoring in Chemistry.

Riezenman is also the author of PairIt!, the highly acclaimed Food & Wine Pairing app for the iPhone and Android, with over 1,000 dishes and 20,000 pairings based on varietals and regions. Bruce’s experience in entrepreneurship and as a chef are marked by his passions for sustainability, culinary arts, quality craftsmanship and technology, topics he continues to explore in both his food and speaking engagements, always applying his innovative California fingerprint on classic international concepts and menus. His approach is really about savoring–savoring the flavor of wine and food and the way they taste together, but also savoring the moment, the place, and the people we share them with. He shares his vision of food and wine as opportunities to enjoy the things in life that truly matter: health, happiness, family and friends. That’s what wine country living is really all about.
