Various governments are considering the implementation of energy labelling on alcohol products as one element of obesity prevention policies. However, little is known about the most effective ways to communicate energy information to consumers. The aim of the present study was to explore consumers' reactions to different energy information provision formats to assist the development of effective energy labels. Nine focus groups (n=83 participants) were conducted with Australian adults who reported drinking alcohol at least twice per month. Participants were exposed to an energy-only information label and labels displaying full nutrition information panels. A thematic analysis approach was used to identify key issues. While few participants were overtly enthusiastic about the mandatory display of energy values on alcohol products, there was general support for the provision of this information to assist those drinkers who could benefit from it. Substantial confusion was apparent as participants attempted to distil meaning from the provided information, particularly where it was expressed in terms of serving sizes and standard drinks. Full nutrition panels were especially problematic in terms of creating a health halo due to the nil or low values for multiple nutrients listed. This was especially notable for information relating to sugar content. Overall, there appears to be inadequate public understanding of the concept of dietary energy in alcoholic beverages and the various terms used to quantify its presence, which is likely to limit the utility of mandatory energy information provision requirements unless they are accompanied by effective community education.
