Im pretty stoked off this brand, it's super simple, basically just added sugar and vitamin c. I usually add maybe 25% more water to it and it's still good. It's made in Mexico. Basically any juice that has Hawaii in its name is also fuckin fire. Not a big fan of corn syrup in most drinks, it always has a weird, lingering, thick aftertaste. Highly recommend trying out the juices in the international section of grocery stores, there is always something good there. The US sucks ass at making good juice mostly
Not generally big on juice since I'd rather get the fiber from whole fruit, but you're right nectar is amazing, really good for cocktails in particular
I guess the naked juices and similar are what I'd go for if I had to pick a juice. At least it's pretty good for getting some vitamins and shit when I'm having a hard time mustering the energy to feed myself properly
