There are days when I want a sweet, crisp apple, and there are days I have a serious hankering for a good ol' granny smith.
Even the classic Red Delicious - which gets a really tarnished name in current pop culture is actually a damn good apple... soft, slightly chewy, sweet - but not too sweet, a little hint of bitter in the skin - it's just a different experience than the super sweet, juicy apples that start to just taste like apple juice.
Then again - I really like apples, and I'm vaguely suspicious that the site maker just likes sugar water.
