Wine connoisseurs, or simply those who can’t discriminate between the good and bad of the grape, can sharpen their wine-tasting skills at a workshop presented by Ann C. Noble, a renowned authority on wines. The seminar will be held from 6 p.m. to 10 p.m. Monday at Festivities at the Old Post Office. Noble will demonstrate the use of the wine aroma wheel. Andrew Snyder, viticulture instructor at Redlands Community College, said the use of the wheel during wine-tasting helps people recognize and remember specific details about wines. Novice tasters often complain that they “cannot smell anything” or can’t think of a way to describe the aroma of wine, but the nose can be trained and brains can connect to link terms. Reservations for the event can be made by calling Kinsey Hull at 422-1228. Cost for the workshop is $59.95. Noble is professor emeritus of the University of California Davis and an authority on sensory sciences or “sensometrics.”
