Sounds like a project worth the effort. I’d start with the obvious: aroma, body, flavor, finish, and finish. Then add the less obvious—like the “mood” it evokes, its pairing potential, and any quirks in its label design. If you keep everything in a tidy spreadsheet or a database with tags, you’ll have a clear map and you can always add more columns later. Just remember to give each beer its own little “profile” page; that way you won’t mix up the Hefeweizen’s “sweet citrus” with the IPA’s “hoppy burn.” Happy cataloguing!
