Apple juice and apple cider are both fruit beverages made from apples, but there is a difference between the two. Fresh cider is raw apple juice that has not undergone a filtration process to remove coarse particles of pulp or sediment. It takes about one third of a bushel to make a gallon of cider.
To make cider, apples are simply cored, chopped, mashed, and then pressed to extract their liquid. Most cider is pasteurized before sale, though unpasteurized cider is also available.
To make apple juice, manufacturers follow the same steps used to make cider, but they also filter the extracted liquid to remove pulp and sediment. Apple juice is then pasteurized, and potassium sorbate (a preservative) is often mixed in to prevent fermentation. Finally, apple juice is sometimes sweetened with sugar or corn syrup.
Apple cider and apple juice are not necessarily interchangeable in cooking. Apple juice has a much sweeter taste while apple cider is more acidic. The filtration process used in making juice removes some of the complex, tart, and bitter flavors that are still present in cider. When it comes to cooking, don’t swap apple juice for cider.
