What is the “304” referring to?

I don’t totally understand how this chart is segmented and I’d challenge the accuracy of it. For instance, Oreo is a brand by Nabisco which is a subsidiary of Mondelēz but the chart shows Oreo and Nabisco in separate boxes.

You might be thinking of Fred Meyer, which is red.

Cool! Thank you for sharing

Do you have any resources for N/A cocktails that you are particularly fond of? I’m taking a bit of a booze break but finding this community got me feeling crafty.
