The major disadvantages of this type of machine are the noise, heat, and oxidation resulted from their great speed. This oxidation can cause a loss in nutrients in the juice, thus reducing the juice quality and fridge life. Besides, while they’re good for thick, hard, crunchy fruits and veggies, these juicers are much less efficient in handling leafy greens.
In researching this guide, we spoke to John Kohler of DiscountJuicers.com and Matt Shook of JuiceLand in Austin, Texas, to find out about leading juicers and to compare similar models. Though we don’t normally seek out retailers as experts to interview for our guides, John Kohler is different—we think he’s the most knowledgeable juicer on the Internet. He’s been juicing for 25 years, and his YouTube videos comparing and talking about juicers and juicing have over 27 million views. Wirecutter founder Brian Lam wrote the original juicer review for Wirecutter, using John’s knowledge as a guide. Because Kohler stocks all brands of juicers and his reviews are objective, we don’t think he’s biased toward any particular models.
Equipped with a 1000-watt powerful motor, this easy-to-use juice extractor makes it exceptionally convenient to enjoy fresh, healthy fruit and vegetable juice from the comfort of home. The unit's large 3-inch feeding chute can accommodate whole apples, pears, and other large-size fruits and vegetables (extra-large items may need to be cut into smaller pieces first).
Kuvings released the C7000 in 2017. Kohler said this model has improved features compared with the Kuvings Whole Slow Juicer (B6000), which didn’t impress us in testing. From watching a comparison review of the C7000 and the Whole Slow Juicer, we see that the C7000 has a new funnel for easily feeding produce, doesn’t produce as much pulp, and has a more recessed auger for easier cleaning compared with its predecessor. But the C7000 still spins faster than our pick at 60 rpm, and is more expensive at the time of writing. And although Kuvings juicers boast a 3-inch feed tube that, in theory, can accept whole fruit, most apples in the store are much bigger than three inches in diameter, so that’s a wash. When we tested the Whole Slow Juicer, it didn’t hold a candle to the juice quality from Tribest or Omega machines. The Kuvings Silent Juicer was also an underperformer, giving us over an ounce less of green juice than the Slowstar. The resulting juice was also unpleasantly pulpy.
