A cold press juicer is also known as a masticating juicer. To masticate is to chew, so it follows that a cold press juicer squeezes the juice in a “chewing” fashion that is slower and more deliberate than the automated machines on the market.A hydraulic press is involved in cold press juicing, which takes more time and patience. However, the end result can be even more delicious than what you get from regular juice extraction. As you shop for the best citrus juicer for your needs, take note of which juicers offer “masticating” capabilities.
