If this was me, and I used to just keep a notebook of the wines I liked, there's a couple ways to go about this.

Edit: in the Fdroid store theres an app named Cavity (terrible name) or Wine cellar that might be what you want for your own wine tracking.

Info on new wines is simply not going to come for free (or "free") bundled in an app unless you make it yourself. But wines you try is a much easier thing to track. If you can just accept they need to be 2 different things, it an easier task.

IMO, what you want is to create and self host a survey that let's you easily and quickly enter year, location, attributes, photo of the label, notes, etc. Depending on how granular you get with flavors and tasting attributes, you could get in a groove and log a wine with dizzy thumbs and low light in a minute or two. Then you just decide where that data lives, and how to get it back into a spreadsheet or SQL db to search it.

You could do most of this in a Google form/sheet, though you'll simply get nagged and tracked later in more subtle ways.

I'll be real honest, I suggest you ask ChatGPT on options, and suggest things like you want to build a survey in HTML (it'll do this for you) that lives on a device and is bookmarked for easy access, sends data to, let's say a Dropbox file you access with an API, and you use another HTML page you save locally to search.

For real, let us know how it goes, because I would all get some use from this.

You could self host an inventory management software

If they're not selling your data, they have to get paid somehow. Pay for the premium subscription.

Do you run docker containers? If so this might be helpful https://github.com/sredna43/cellarman

Is there anywhere to search for web 1.0 apps? The new info would probably be dead, but you could at least have wines through the early 2000’s in it.

Why not buy a wine journal?

Spreadsheet? Why does it have to be an app?

I just started a spreadsheet for tracking coffee beans
