It wasn't about the line at the facility they are utilizing, it was about a sudden change in the availability of aluminum. I mentioned this before and it didn't register with everyone here. When they have the aluminum secured, which by the way was previously MUCH easier (like a fast food drive through), they will get immediate access.
Their arrangement is an "exclusive" one. If you listen to the podcast closely you'll hear it mentioned, but I believe they got into it in more detail in one of the previous podcasts. Aluminum shortage is not the same as your co-packer(s) shoving you aside for another partner, and their arrangement with that local co-packer is a sweet one.
The huge companies like Coke already had a huge aluminum inventory which keeps them temporarily buffered from situations like the tariff created aluminum availability situation that just occurred. They keep vital supply inventories high just for that reason, and it's much easier financially for them to do that.
