An excerpt from the article 18 facts about pears

Summer and autumn varieties are harvested before the fruits ripen, when they are still green, but break off as they lift. Winter varieties are harvested at different times, the first harvest is usually about two weeks before ripening, the next about ten days later about the last when the fruit is ripe. In this way, fruits picked at the end are consumed first, while those picked at the beginning ripen later and you can enjoy the taste of the fruit longer.
