From this article on a Scottish study of the health benefits of drinking cider, I learned the following critical difference between what we in the U. S. and Canada call cider and what you get if you order the drink of that name elsewhere:
What is Cider?
It is an alcoholic drink made from apples which are first crushed and then fermented. In the USA and some some parts of Canada it is known as 'hard cider' - in those parts, the term 'cider' can often mean non-alcoholic apple juice. In the rest of the English-speaking world 'cider' refers only to the alcoholic drink.
Cider usually has an alcoholic content of 5% or more. It is generally stronger than beer. The British are the greatest cider drinkers in the world. In the UK it is available in many forms, such as sweet, medium or dry.
Not to mention the fact that the writer of the article has no idea that in the United States, at least in the Northeast, real cider—unpasteurized, unfiltered, varietal—is one of the most delicious drinks in the world. "Non-alcoholic apple juice"? You might as well describe Everest as "a mountain" or Shakespeare as "a playwright." True, as far as it goes, but it misses nearly everything important.
