Why is it important to sniff the entry immediately after pouring?

Sniffing the beer immediately after pouring is crucial for ensuring a proper evaluation of volatile aromatics. The aromatic compounds in beer are often volatile, meaning they evaporate quickly from the liquid. By smelling the beer right after it is poured, a judge captures these volatile aromas while they are still present and most pronounced. This immediate aroma assessment allows for a more accurate and comprehensive evaluation of the beer's profile, contributing significantly to the overall sensory experience and judgment.

Other aspects like visual appeal, alcohol content, and carbonation level can be influenced by various factors but do not directly pertain to the immediate aromatic experience provided by the beer. Therefore, focusing on the volatility of aromas is essential for correctly interpreting the beer's character and quality.
