A wine cellar that remembers what you used to believe

Developer Ken Walger has introduced 'Cellar,' a unique wine collection management application built for the Sanity Challenge. Unlike standard inventory apps that only track current status, Cellar functions as a temporal ledger. It stores events—such as acquisitions, consumptions, and dated assessments—rather than static fields. This allows users to query the state of their collection at any point in history, revealing how drinking windows and inventory levels have evolved based on past beliefs and tasting notes. The project utilizes a pure TypeScript core to interpret data from Sanity, separating business logic from the CMS. Walger highlights his development process, which involved rigorous 'gate-based' testing with AI assistance, ensuring that the system remains auditable and accurate. By treating data as a series of claims rather than absolute truths, Cellar provides a sophisticated way to track missed opportunities and future drinking windows, demonstrating a powerful pattern for any event-sourced application.
