Twin gear triturating machines are usually the most expensive juicers offering the best juice yield. Twin gear juicers employ two metal counter rotating gears to crush the juicing fodder. The precise tolerance of the gears allows the juice to flow through the gap between the gears while the large pulpy matter passes along the top of the gears and is discharged.
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.
The Hurom comes with a lidded pitcher for collecting juice, but its slow-turning auger produced so little splatter that we also had no problem putting our own glass directly under the juice spout. Clean juicing makes for means you’re not beholden to the Hurom’s pitcher, making it easier to juice straight into your to-go cup and reducing counter clean-up. (When we tried this with the Juiceman, we ended up with a foot-wide splatter radius.)
If juicing leafy greens is an emphasis for you or you want a machine that handles other kitchen prep the Omega J8006 is your best choice. This classic cold press masticating juicer has been a best seller for years and produced the highest volume of kale juice of all the juicers we tested. It works quietly at slow speeds (only 80 RPM) to extract juice from all kinds of produce. Its dual-stage juicing system mimics how humans chew–the crush and press process produces drier pulp and high juice yield. We did have to spend more time cutting fruits and vegetables up to fit them into the small feed tube and occasionally had to stop juicing and use the “reverse” feature to handle clogs. It also produced slightly less juice from hard fruits and vegetables and as a horizontal model has a bigger countertop footprint. However, it offers additional functions such as pureeing nuts into nut butters, grinding spices and coffee, making pasta, and baby food with an extremely generous 15 year warranty.
If you're serious about juicing, it's best to get a juicer that fits nicely on your kitchen counter so you can leave it out rather than having to haul it out of a cupboard. That means paying close attention to the dimensions and even the length of the electrical cord. You don't want to buy a juicer that looks great in your kitchen but doesn't have a cord that reaches the outlet.
Whereas the Omega J8004 is a commercial-quality machine, the Omega NC800 is designed for household use. When it came to green juice, the output was almost identical. The carrot juice was a different story, though. The NC800 yielded only 12.3 ounces. John Kohler at DiscountJuicers.com said that this machine put out 15 percent more juice than its predecessor, but we found that it actually put out 25 percent less carrot juice than the J8004. The nice feature of this juicer is that it boasts a larger feed tube than its predecessor, which makes prep a little easier.
