I haven't been able to find this since 2003, the last bottler that had it that I knew of was Coca-Cola of Northern New England.   apparently they're testing this with independent bottlers again because I found this in the midwest from an independent Coke bottler.   Hot off the presses folks!   Fresh stock purchased 11/2019.  With the pandemic, bottlers scaled back variants of main brands and this may not be produced any longer!
