What is the best practice for effectively smelling a beer?

The practice of using short quick sniffs is effective for smelling beer because it allows the nose to capture the complex array of aromas present without overwhelming the sensory receptors. When sniffing beer, the goal is to identify different scents and nuances, which can be easier with short, brisk inhalations. This method keeps the olfactory system engaged and helps in distinguishing various aromatic components, such as hops, malt, or any additional ingredients like fruits or spices.

Long inhalations might lead to olfactory fatigue, where the nose becomes saturated with the aromas and struggles to detect more subtle notes. Covering the nose while breathing would obstruct the ability to smell, leading to a poor assessment of the beer's aromatics. Additionally, sniffing directly from the glass can trap volatile compounds in a way that may not maximize aroma detection, especially if done incorrectly. Therefore, using quick sniffs strikes a good balance, allowing for a more nuanced appreciation of the beer's bouquet.
