luvs, the cider i love, called magner's irish cider, aka bullmer's cider, is consumed cold. i like to get a side of ice with mine to keep a few cubes afloat in the glass.
for a warmed cider, try adding spiced rum to (room temp) apple cider and a little hot water. i've even seen people add lemon wegdes stuck with cloves to this concoction.
