Wine label information is an important aid for consumers in making purchase decisions. However, the influence of label information types in the context of sparkling wines is poorly un-derstood, despite the global growth of this product class. Using an online survey of 576 Ontario sparkling wine consumers, we sought to examine this knowledge gap using two complementary approaches. First, participants were presented with a set of two mock sparkling wine labels, selected at random, from a set of eight conditions. One condition (control) contained all seven of the information types from Shaw et al. (1999) (endorsements, parentage, attributes, target end use, target end user, manufacture, nonpareil), whereas the other seven omitted one of each of these elements. Respondents then rated their willingness to buy, willingness to pay, and the perception of quality. Lastly, they self-rated the importance placed on 14 different label information statements when purchasing sparkling wine (5-point Likert scale from 1–not at all important to 5–extremely important). Results show that including a description of the wine’s sensory attributes on sparkling wine labels is important to consumers overall, except for those with a high subjective knowledge of sparkling wine, and those who normally spend more than CAD 30 per bottle, as these groups are more willing to buy, willing to pay, and rate their perception of quality higher for labels that do not include attribute information. Grape variety/blend and production region information are rated high in importance. Alcohol content is more important to young consumers and those who prefer Prosecco-style sparkling wines, whereas vintage/year is more important to consumers who prefer Champagne-style sparkling wines. Expert endorsements are rated low in importance, and younger consumers are more willing to buy sparkling wine with the endorsement information removed. We conclude that sparkling wine label information content should be optimised for different market segments and consumer characteristics. This study provides important insights that can guide sparkling wine marketers and retailers in this process.
