2 hrs on Sat 2/11, 12:30-2:30, for the first 12 off-flavors
2 hrs on Sun 2/12, 12:30-2:30, for the second 12 off-flavors

seminar will wrap at 1:45 each day to allow you time to drink your good, wine-barrel-aged beer and to chat with your fellow off-flavor explorers
This seminar will be led by Rich Higgins, who is a Master Cicerone, professional brewer, and beer educator. For each off-flavor, we'll taste a beer spiked with that off-flavor and compare it to an untainted control beer. We'll learn how to identify each flavor, covering the common descriptors as well as coming up with our own so that we can broaden our skills at detecting these flavors. For each, we'll also learn the chemical compound, its source, and discuss what a brewer or retailer might do to avoid this flavor's development in a beer. This is a great seminar for beer geeks, brewers, homebrewers, BJCPs, and Cicerones studying for Advanced- and Master-level exams.
Attendees must be 21 years of age or older.
