Grape nuts are excellent with apple juice and in fact I think they are the best cereal for introducing new victims to the joys of eating cereal with apple juice.

(I acquired this habit as a small child when I was allergic to milk. I'm not allergic any more but still think most cereals taste much better with apple juice on them - especially dark, branny cereals such as Wheat Chex or Cracklin' Oat Bran. Not recommended for excessively sweetened cereals or those with marshmallows. Dried marshmallows tend to dissolve rapidly in the apple juice, creating an unpleasant gummy sludge.)
