Green vegetable juices are the back bone of the
nutritional regimes that I encourage people to follow.
To get juice from kale, spinach and even wheatgrass
you need a machine that literally crushes and squeezes
the juice out of these more hardy plant foods. The more
commonly found and usually less expensive centrifugal
juice machines make juice quickly and are relatively
easy to clean. They don’t, however, juice leafy
greens effectively and can’t be used with wheatgrass.
The most efficient machines are twin gear juicers, but
they are big, expensive and quite complicated to dismantle,
clean and re-assemble. (You
can read more and see examples here).
With this in mind I recommend single auger machines.
These are efficient with dark leafy greens and other
produce. They take up relatively little space on the
counter top and can be cleaned quickly and efficiently.
The best all-round high quality juice machine currently available is the Omega VSJ84R
Vertical auger juicers have several advantages over
horizontal models. They take up less counter space than
horizontal models. The gravity feed over the large auger
gives highly efficient juicing at slow speeds.
