Masticating juicers mimic "chewing" fruits and vegetables, using augers with sharp metal teeth. They then press the maximum amount of juice from the pulp, which results in high yields and very little foaming or oxidization. This slow juicer technique allows for easy juicing of leafy greens, such as wheatgrass, spinach, and kale. Also known as "cold-press" juicers, masticating juicers take more time to produce juice but don't heat it up. That is thought to preserve more nutrients in the final juice. These juicers tend to be quieter and operate at a low hum. Their stronger motors come at a higher cost but enable additional features like making nut butters, baby food, sorbets, and even pasta. Masticating juicers cost upwards of $200 and are more of an investment for the serious juicer.

Masticating juicers are much slower than centrifugal juicers, so if you're going to skip making a juice in the morning because it takes too long, this isn't the product for you. However, they do extract almost all the juice from the plant fibers (resulting in a "dry" pulp) and since no air is introduced into the juice as it's being made, it means you can make a big batch at once time and store it in the fridge. Masticating juicers are ideal for lettuces, kale, wheatgrass and other leafies, since almost no juice can be extracted from them with a centrifugal system. If you're into making green drinks, don't bother with a centrifugal juicer, go directly to a masticating type. Breville, Hamilton Beach and Omega are all well-known juicer brands for both types machines.
