Thanks for the bug report, there is some pretty hefty security that is loaded on the site, and I'm still getting some false positives. Please try again, and see if it goes through this time.
Currently, the site gets a lot of it's data from
http://brewerydb.com , which is probably where that ABV of 6.0 vs 6.2 is coming from. Eventually we'd like to have a way to submit updated data back to that system, but there's nothing like that in place.
Thanks for the feedback on the save button location, that's a very good idea.
Also, while the comments field can be used for a description of the beer, after you've saved the item for the first time, you should see another place to put description and images (on the right hand side of the screen if on a pc, or below if mobile). Those descriptions are automatically being loaded from brewerydb when available, but you can also submit a description there yourself if it's blank or needs to be updated.
We really appreciate your feedback!
