Sorry, my mistake

The bottles that MBV uses appear to be LDPE, which should be fine for juice storage with no leaching for at least a month. In doing bottle research, I've read that there
might be some leaching with LDPE and reactive juices (citrus, cinnamon, etc) but it is my understanding that this only occurs in the long term. Since they are often blow-molded, it's possible that there will naturally be variation in wall thickness because of the process itself. I wouldn't jump to conclusions about the juice eating the bottle away if you just got it, and someone with a Reo might really like to have that bottle for squonking
Specialty Bottle is a popular source among DIYers for bottles. There are other choices as well...some even buy them on ebay. I'm partial to the cobalts, and I prefer to get them from the same place if possible (they look more organized if they are all the same).
