Cranberries

Cranberries grow on groundcovering vines in the Northern Hemispheres of Canada, United States and Europe. The berries are dark red and are commercially harvested between September and December. They are related to the billberry, blueberry and huckleberry. There are several different varieties of cranberries and they include Ben Lear, Early Black, Stevens and Howes.

The cranberries are usually grown in man-made bogs or wetlands. The vines of the cranberry plant can reach as long as 2 m, and a height of 5 to 20 cm. The plant produces runners ranging from 1 to 6 feet long. These runners produce short (5 to 7.5 cm), vertical upright branches that are non-trailing. Most of the berries grow on these uprights.

The leaves are a dark green color during growing season, and when the plants go dormant in the fall they become a reddish brown color. The flowers are either white or pink and the berries are white when they first begin to grow, but then as they ripen they turn into a deep red color.

Harvesting

Most commercially grown cranberries are harvested in September and October. 95 percent of the crops are harvested for processing, and only 5 percent are harvested for fresh consumer consumption.

Those that are harvested for processing are processed into juice and juice blends, as well as into sauces, and others are sweetened and dried.

When harvesting cranberries to be processed they are harvested by flooding the bogs with water as high as 8 to 10 inches. The berries are then shaken loose from the vines by a machine that is driven through the bogs. The berries float to the top and are pushed off to one side of the bog where they are collected and conveyed onto trucks or crates.

Cranberries that are harvested for fresh consumption are harvested without flooding, and can take more work. There are several different methods used to pick the berries; one method is with a machine that gently rakes the berries off the vines, mechanical pickers are also used, and in some cases they are picked with a hand held scoop.

How to Eat
