Nomenclature
Although the term cider is used for the fermented alcoholic drink in most of the world, the term hard cider is used for the alcoholic drink in the United States and much of Canada.
In the United States, the difference between apple juice and cider is not well established. Some states do specify a difference. For example, according to the Massachusetts Department of Agricultural Resources, "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. Apple juice is juice that has been filtered to remove solids and pasteurized so that it will stay fresh longer. Vacuum sealing and additional filtering extend the shelf life of the juice." In Canada, the Canadian Food Inspection Agency also regulates "unpasteurized apple cider".
