The high RPM associated with centrifugal juicers also generates a lot of foam which drives more oxygen bubbles into the juice, resulting in the lower shelf life of the juice. Juice extracted by centrifugal juicers spoil rather quickly due to the oxygen-laden foam and must be consumed immediately. With this, you cannot hope to make a bulk of juice and store for later.
The Tribest Slowstar, a vertical single-auger, slow-press juicer, is the most versatile juicer we’ve found, efficiently handling thick greens, fruits, and root vegetables. In our tests, it yielded the highest amount of green juice and nearly the highest amount of hard-vegetable juice with low effort, experienced no motor jams, and generated minimal foam. It also has a generous feed-tube opening, which makes for quicker prep and easier juicing. This quiet machine is backed with a 10-year warranty that covers the motor and parts, one of the better guarantees among the juicers we tested.
During juicing and cleanup, we also took note of how easy the machines were to use and clean. To see how efficient each model was at extraction, we measured juice yields by weight. In addition, we checked how much pulp was left over, looked for foam (which can be a sign of oxidation), and took note of if juicers backed up or jammed during juicing. We also measured the temperature of the juice, and compared it with the temperature of the produce we started out with. Finally, we tasted each juice for freshness and pulp, docking points from machines that yielded juice with unpleasant levels of fiber. Flavor is also an indicator of how much of the greens actually made it into the glass—sweeter juices had more grape and didn’t do as good of a job juicing greens.
Unlike fast juicers which spins at more than 10,000 rpm to extract juice, this machine does the job with an auger turning and squeezing the fruits/veggies against the chamber wall. This minimizes exposure of the juice to the air, thus preventing oxidation of the nutrients in it. Plus, with a slow speed, you don’t have to worry about the little enzymic biological molecules being “boiled up” by the heat from the motor and destroyed.

Juicing advocates advise that you start with a basic, centrifugal juicer-only model so you can get the hang out of juicing. You can then move on to the multitasking masticating and triturating ones as soon as you become adept at juice extraction.

The commercial-grade Omega J8004 juicer does best with hard fruits and vegetables, and was more efficient than popular (and still great) juicers like the Breville Juice Fountain Plus we tested. It’s great for people on a budget with limited counter space. And with a 15-year warranty, the machine is built to last. In our tests, the J8004 extracted a fair amount of both green juice and carrot-apple juice, falling in the middle of the pack for both tests.
Although I don’t claim to be a healthy-living enthusiast, I do regularly enjoy grassy green juices and spicy beet turmeric shots myself. I’ve personally owned a few different juicers over the years—including long-term testing our picks for the past three years—and I also have a lot of experience working with the commercial Champion juicer in restaurant kitchens.
The Hamilton Beach’s 3-inch chute was a breeze by comparison: We were able to drop in large apple halves and entire celery stalks without a problem. Most budget competitors we tested had an extremely narrow feed chute that required us to chop our apples into sixteenths to get them to fit — a process we’re reluctant to commit to for our daily juice.
The gist: This Hamilton Beach model is perfect for either those who are just getting into juicing or even seasoned juicers who simply don't want to break the bank by spending several hundred bucks on a juicer.  It cranks out 800 watts of power and has a 3-inch-wide chute that you can fit whole foods into (for example, a whole apple), so you can spend less time cutting and prepping. All of the juicer's removable parts are dishwasher safe, which makes clean-up super easy. Plus, it even comes with a handy cleaning brush.
Another important consideration is where you plan to store your juicer and how easily you’ll want to access it. While horizontal-masticating juicers can churn out high volumes of juice, you may not have space for them. Plus, they tend to weigh more so tend to be difficult to move from closet to counter. The small footprint of vertical juicers is ideal for smaller kitchens with limited counter space and can often tuck under cabinets. Lightweight centrifugal models are perfect if you need to move your juicer from storage space to counter. Just make sure whatever model you pick can handle the volume of juice you plan to make: smaller juicers equal smaller amounts of juice per batch.
