What is Apple Juice?
Apple juice is made through the pressing of apples, of which there are hundreds of varieties in the world.

After the apples are pressed, most juices are further filtered or pasteurized, which helps to remove any particulate matter, resulting in a thinner consistency of the final juice.
McIntosh apples are the most common types of apples used to make this delicious juice and China is the largest producer of apples in the world. Apple cider, which is often confused with apple juice, is unfiltered and unpasteurized liquid initially pressed from apples, in addition to being fermented.
