Juicing Basics blog has a nice post on the “different levels” of juicing and/or juices – ranging from juicing with only organic produce from a garden or farmer’s market, to juicing using standard grocery produce, to purchasing pre-made juices off the store shelf.

My favorite line:

In any case, even if you just use standard produce in making your juice, it’s still a world away from buying pre-made juice. If organic produce wins out over supermarket produce by a yard, making your own juice wins over store-bought juice by a mile.

Couldn’t agree more.
