mason jars

For Champion OR Green Power (green power/star is better but)
Buy mason jars, small ones (16 oz I believe?). Fill the juice to the brim, then put on the lid. This should seal out pretty much all the air. Then refrigerate the juice, or put in a cooler. This helps prevent oxidation and breakdown in the juice. Using this method, if you need to make the juice ahead of time, it can certainly last 24 hours, perhaps 36 hours (for green power, probably 48?)
Obviously not good as drinking it fresh, obviously there will be some loss BUT it is better than just putting it in a cup or thermos etc. Or if you put it in some other container, put cellophane/saran wrap onto the surface of the juice. But I'm thinking that probably puts plastic in your juice. Tweet
