Although numerous varieties of peaches are grown, they are often categorized according to the way the flesh of the fruit is attached to its pit. Clingstone peaches have flesh that clings firmly to the pit, while freestone peaches allow the pit to separate easily from the fruit. The most popular variety of peach is the Elberta (a freestone); it makes up about half of the peach harvest. Some of the newer varieties of peaches on the market today include a peach with creamy white-flesh, and a short, rather flattened variety called a Donut peach; both have excellent flavor.
