What this question tests

Product sense for reducing decision-paralysis in a low-frequency, high-anxiety purchase.

Clarify context: an in-store shopping companion versus a broader wine-discovery app.
Pick the in-store companion, since 'at a grocery store' implies physical shopping.
Identify pain points: overwhelming selection, uncertainty about pairing or quality, and no sommelier available.
Propose a scan-a-bottle feature for ratings and pairing suggestions, personalized recommendations, and a budget filter.
Prioritize the scan-and-recommend feature first, since it directly reduces in-aisle decision paralysis.
Define success as percent of scans leading to a purchase, or reduced time-to-decision.

Grounds the solution in the physical in-store context, a barcode scan, rather than a generic wine app.
Names the specific anxiety, fear of picking a bad or mismatched bottle, as the core pain point being solved.
Adds a budget filter, recognizing price sensitivity varies for casual grocery wine buyers.
Picks scan-to-purchase conversion as the success metric, directly tied to reducing decision friction.

Designing a broad wine-education app disconnected from the specific in-store, in-the-moment use case.
Not addressing why existing shelf-label or ratings apps aren't already solving this.

How would you get accurate real-time inventory and pricing per store?
How would you personalize recommendations for a first-time user with no purchase history?
