According to the website Well Pared, California originally spawned the juice trend in the 1970s. Californians’ association with juicers, however, dates back to a man named Norman Walker, who invented and built the first electric contraption in the 1930s in Anaheim. Although manual equipment existed to extract juice from fruits and vegetables, Walker believed these important nutrients were left behind (via The Atlantic). His machine, called the Norwalk, grinds vegetables and fruits more finely than existing manual tools. Interestingly, his company was still making high-end juicers (about $2,500, per The Atlantic) until 2021, when it went out of business.
There are four types of juicers, according to the Goodnature website: masticating, twin gear, cold press and centrifugal. Most home options fall into this last category. Quick and relatively inexpensive, a centrifugal juicer allows the user to push fruits or vegetables through a tube, where a spinning blade cuts them. At the same time, the pieces move through a sieve, which removes the liquid. Amazon has a great selection of centrifugal juicers that cost less than $100.
If you’re looking for the best option, though, according to several experts at Tech Radar, cold press juicers are better. Better at extracting juice from leafy greens and berries than centrifugal machines, they work by using hydraulic or pneumatic presses to pressurize edible fruits or vegetables—however, they cost around $500 or more. Oh, and the second state juicer is the most googling? That’s Nevada. Must be the West Coast thing.
