We have a bottling company here in town, I used to do some work there (security Cameras)
The actual bottlers are a independent bunch, they have a bottlling company and get contracts with Pepsi, Coke etc to bottle and make Fountain syrup. Seems rather independent and not related to which Soda is popular today.
They bottled Pepsi and Vess and a few small beverages when I was ther (25 years ago). I know the owner and he is doing well, not fabulous but well. He got really busy a few years back when Pepsi opened a distribution warehouse close to him.
Any of the "bottlers" can bottle RUSH products. May be one this week another next week.
