GlowGrain is a new kind of breakfast cereal made with a nutrient-dense seaweed blend. While health-conscious consumers are curious about it, many are hesitant to commit to buying a full box without knowing what it tastes like. In response, the company partners with gyms, smoothie bars, and wellness expos to offer free single-serving sample packs to potential customers. Which product attribute is the company trying to influence to encourage adoption?
