Most consumer packaged foods and beverages operate this way. The level of concentration of manufacturing and packaging is depending on the product ingredients and market demand.

Soda is easier to ship at the syrup stage. Make a big concentrated sticky goo and send it to bottlers located in a strong market who dilute it down into consumer products and package for final distribution which tends to be local. So you end up with a few HQ syrup makers and a bunch of bottlers

Ice cream typically doesn’t work this way because dairy isn’t stable over long times and requires refrigeration at a certain point. So a company like B&Js works to convert that milk quickly into dairy products that are more stable, like ice cream. But that requires a closer manufacturer and packaging network.

So you don’t typically see “local” ice cream brands with non-local packaging but B&Js is a global product hence the additional locations. The product just ended back up in VT because global trade is super complex and it genuinely may have been cheaper to produce that pint in the Netherlands and ship it to the US than to produce it in the US.
