If you're buying domestic juice you pay a premium for nothing special, from what I can tell. Also, the chances of it being made in a proper factory are basically nil. It's often someone else's DIY garage juice at a 10000% markup.
I haven't kept up with the new FDA guidelines since starting DIY about a year ago, but from what I remember a lot of the little garage brands are going to be in trouble. My buddy used to work at Apollo out in Concord and I know they take their juice seriously. I think it's shitty, but it's not because the line is dirty haha. Molecule Labs out in Benicia has a pretty cool facility as well.
