Thin legs in bourbon typically indicate what?

Thin legs in bourbon are primarily indicative of a lower proof. When bourbon is poured into a glass, the way it interacts with the surface of the glass can reveal important characteristics about its composition. Legs, or tears, form as alcohol clings to the sides of the glass and then slides down in a manner influenced by the bourbon's viscosity, which is a result of its alcohol content and other components, such as sugars and glycerol.

In the case of lower proof bourbons, the liquid tends to have a thinner or less viscous texture, resulting in thinner, faster-drifting legs. This characteristic arises because lower proof spirits contain more water in relation to alcohol, leading to reduced interaction that generates pronounced legs. In contrast, higher proof bourbons typically display thicker, slower legs due to their elevated alcohol content combined with various compounds that contribute to a more viscous mouthfeel.

Ultimately, recognizing the significance of leg thickness is crucial for bourbon aficionados and professionals, as it can provide insights into the spirit's overall profile and quality.
