The promotion of youth-friendly city construction has been incorporated into the national-level youth development plan. In recent years, China's fruit wine market has shown a rapid growth trend, with young consumers becoming the primary consumer group. This study systematically reviews the current state of fruit wine packaging design and identifies issues such as homogenization in visual presentation and superficial cultural expression, misalignment between market positioning and diverse consumption scenarios, and insufficient sustainable consideration of functional design. To further clarify the focus and user attention of the current fruit wine packaging design, the analytic hierarchy process (AHP) is employed to experimentally evaluate youth-friendly demands. The results indicate that graphical patterns in the visual layer, reusability in the functional layer, social gathering adaptability in the scenario layer, and gamification and entertainment in the interactive layer of fruit wine food packaging design hold dominant weights in the demand hierarchy of the youth demographic. Based on the consumption characteristics of the current youth demographic and the weight results of their demand hierarchy, the "Cosmofruit" packaging design practice is carried out and evaluated across four dimensions: vision, function, scenario, and interaction. This provides theoretical insights and practical guidance for the ongoing youth-oriented innovative transformation of fruit wine packaging design.
