When a beer is at room temperature, the chilled glass brings the temperature of the beer down to the optimal flavour range, usually between 4 and 12 degrees Celsius. Beer already at that optimal range (like beer you've kept in the fridge) suffers when poured into a chilled glass. According to Ryan Dorchak, a Certified Cicerone:
"It's a cold, harsh realisation to come to terms with the fact you've been pouring expensive beer into a glass and losing the flavour profiles the brewers worked so hard to perfect."
