This is enough juice for 2-3 servings. It will yield between 30-40 ounces depending on the size of the veggies you use as well as the juicer. We juiced with the Green Star Juicer (a twin gear juicer), our first pick for a greens juicer.
The Green Star Juicer will yeild the most juice and give you the highest quality juice of all our juicers. The only downside is that it takes more time to juice with a twin gear juicer than a centrifugal juicer, a bit more elbow grease, as well as clean up time. If you have the extra time to spend juicing, there's no substitute for the Green Star Juicer.
On the other hand, if you are someone that needs to juice and get out the door, you may want to consider a centrifugal juicer like the Breville Juice Fountain Elite. It does well on greens and is the most efficient and solid centrifugal green juicer we have ever used or sold. We sell more Juice Fountain Elite Juicers than any other juicer in our warehouse. Customer satisfaction is high on both juicers.
One other thing to consider is the Green Star Juicer will juice wheatgrass where as the Juice Fountain Elite will not.
Happy Juicing!
