That sucks. I see the value in that, and I can add a tag for it. Imagine maintaining a consistent status for that automatically would be hard though. So the meaning of such a tag would likely become "They had at least one gluten free option at one time".

For venues publishing their drafts, cans or bottles publicly it could be possible to create some confidence interval if we scrape the data and keep history of it.

Thanks for checking it out and leaving a suggestion for improvement!

They are becoming more common, as it's very simple to make them GF- you can simply add an enzyme that eats up the gluten. Bristol Beer Factory's whole range is GF and very tasty (my local brewery).
