i agree with the above. i am a part time quality produce control clerk at a grocery store. when choosing an apple look for one that has a good weight to it and the skin is firm. look for bruising spots. circle your fingers around the top of it and if it wrinkles....its probably not the freshest one there.if the stem comes out to easily ..that's another clue. also when displaying apples we rotate them when displaying them....putting the newest ones on the bottom of the display or the furthest out of normal reach at the back of displays. hey now that you know this....be kind and don't ruin our displays too much. its a lot of work !
Follow the advice of refreshme when purchasing your apples, but also take some time to sample the different varieties. If you like tart and crisp go with Granny Smith, sweet and crisp go with Delicious, semi-tart and crisp choose Empire. There are some great suggestions above ...hope you enjoy finding your favorites.
