My Bottle Collection is a web based application designed for individuals who collect whisky, wine, and spirits. The primary function of the tool is to provide a centralized online cabinet where users can catalogue their physical bottles, track their status, and maintain a personal record of their collection. The service is free to use and operates without advertising or visitor tracking. Users can document each bottle with up to three photos, record bottle details, and attach tasting notes, creating a visual and informational archive that goes beyond a simple list of labels. The application supports a structured workflow for managing a collection over time. Users can log key dates for each bottle, including when it was received, opened, and finished, as well as track completed pours and tasting notes. The system allows for flexibility in data entry, such as leaving unknown dates blank or marking estimates as approximate. Collection views are available in card or list formats, with search functionality across the entire cabinet to locate open bottles or identify missing details. The platform also includes a wishlist feature for future acquisitions. For sharing and collaboration, My Bottle Collection offers controlled access options. Users can invite others to view their cabinet or share a specific view through a public link. Privacy controls allow the user to hide sensitive information such as photos, prices, notes, and remaining stock from shared views. Additionally, the application provides optional integrations with ChatGPT and Claude, enabling users to interact with their collection data through conversational AI. The website also hosts practical guides on topics such as cataloguing a whisky collection and maintaining a bottle tasting journal.
