Explain in English
Cider is an unfiltered juice or fermented beverage made from apples. In the fall, there's nothing like a mug of hot, spiced cider.
Apple cider is a darker-colored, unsweetened version of apple juice — the main difference is that cider is fresh, with a short shelf life, and it isn't filtered. Another kind of cider is this same pressed apple juice, allowed to ferment and become alcoholic. This is often called "hard cider." The word comes from the Old French cidre, "pear or apple cider," ultimately from the Hebrew shekhar, "strong drink."
