Freestone — the pit falls out easily. These varieties have firm texture, low sugar content, low juiciness, and white or yellow flesh. White flesh peaches may be slightly less sweet and lower in acid than yellow flesh peaches.
Clingstone — the flesh clings to the pit. These varieties have soft texture, high sugar content and juiciness, and white or yellow flesh.
Semi-freestone — a hybrid of freestone and clingstone peaches. The flesh clings to the pit less tightly and they are relatively high in sugar content and juiciness.
