If you're lucky, maybe you'll find a stack of Jonagolds and maybe one of Empires.
If those are the only apple varieties you're buying and eating, you're missing out. There are hundreds of varieties of apples, many that you've never heard of -- like Laxton's Superb, Senshu, Tallow Pippin, Blacktwig, Wellington, Northern Spy, Oliver and Gilbert Gold.
This website (AllAboutApples.com) has a comprehensive list of these apples. And most of the varieties have hyperlinks that provide you with details on how they taste and when they're typically harvested.
Fall is a great time to visit an apple orchard in your state or region. Once you're there, try some of these more obscure varieties. Many of them make for great eating or excellent pie-baking. The website I referred to above also has a link with listing of orchards.
