Cider is an alcoholic beverage brewed from apple juice. After the juice has been drained of from crushed apples they leave it to ferment in vats (after yeast has been added) and then put in bottles or cans and sold to the general public.
Here is a list of my friends favorite ciders:
Mark A: Blackthorn XXX Strong (the king apparently)
Mike: No answer...
Ric: Doesn't like cider (what what what??)
Jim: No idea.
Mark N: Cider makes him angry.
Brian: Inches (I think...)
Earendil: Wolaver's
Chris: Strongbow (good chap)
