They should have put the bottle size. I found a 500ml bottle tho and turns out the UPC matches. (This was bought from a local store in a 6-pack, but I did buy a case of 12 1L bottles from Amazon once.) So it's the 500ml bottles, then below the label on the back you can find the production date.

From what I can tell it's pretty common for the production dates to be months earlier. My case of 1L bottles that I bought in Feb 2024 from Amazon were produced in *March 2023*. So productions in November would likely have been purchased recently.
