Tours

During the Cranberry Harvest visitors are always welcome. The warehouse is open 7 days a week, September 15 thru October 20. Monday ~ Saturday 8:00-4:30 and Sundays 10:00-3:00.

Your tour starts at the warehouse with a 10-minute videotape taking you through the seasons on a cranberry marsh. You can take a step back in time when you enter the sorting room where the cranberries are still hand sorted just as they were 50 years ago. Sample some cranberry juice and other cranberry treats of the day. Look at the variety of foods and products made with cranberries. The remainder of the tour is self-guided. The warehouse staff will show you where the crew is working and you can walk or drive to a closer parking area and watch the cranberries being harvested. If you have any questions please come back to the warehouse, the staff is always available to answer your questions. Group tours of any size and Bus tours are welcomed ~ please call ahead to make arrangements. Fridays at 10:00 a complete guided tour is offered.
Tours can also be arranged during the growing season starting in June.
All of the tours are free.

In addition to watching the unique harvest you might see some of the local wildlife…we have ducks, geese, eagles, osprey, great blue herons, sand hill cranes, and swans. Some are just here for a day or so as they pass through the area during their annual migration, some stay through the season. The deer abound in the area, but generally come out at night; you might see a few wandering around. We had two moose sighting in recent years; they also pass through the area. Two years ago a mother bear decided to den up for the winter near our irrigation pipe storage area, (she had twins that winter)! The red fox, otter, beaver, and raccoon are also frequent visitors.

Harvest Mid September - October
Alder Lake Cranberry has been here since 1946. We are a family owned, independent grower striving to grow and harvest the highest quality cranberries possible.

The majority of our crop is harvested with cranberry beaters, and bulk loaded into semi-trailers to be used for processed juice and sauce. The beater method does not handle the cranberries as gently as fresh fruit pickers but they are cleaned and sent to freezer space quickly to insure good quality. From the freezer the manufacturer makes juice concentrate, strained sauce, whole-berry sauce and sweetened dried cranberries.

The fresh cranberries which are sold through the warehouse and which you see in the grocery stores are harvested and handled quite differently. Cranberries to be sold as fresh fruit are harvested with cranberry "pickers", these machines have metal "teeth" which gently pull the berries from the vine. The cranberries are deposited in metal "boats" which are pulled alongside the pickers. From there they go into large grain wagons and are pulled to the warehouse where they are unloaded onto a conveyer belt, which takes them to the de-grasser and dryer (a large piece of equipment which has air blowing up through the mesh floor). To insure good keeping quality the cranberries must be dry before sorting or storing. The cranberries at this point can either ride a long conveyor belt to the sorting room or be stored in drying crates (specially built boxes which are constructed so that when they are stacked air flows through and around the berries) each box holds approximately 35 #. The next step in the fresh fruit process is sorting. The cranberries are emptied into the mills from the drying crates. The mills in our warehouse have a patent date of 1932 stenciled on them. The mills have a roller bar which turns and the cranberries bounce over 7 wooden boards, good cranberries bounce, soft (frozen) or damaged cranberries fall straight down and are conveyed to a refuse bin. The lively cranberries roll into the sorting room where workers sitting alongside a moving conveyor belt carefully look over them and pick out light colored cranberries, stray stems, and any damaged berries that did get into the sorting room. The last stage depends on which side of the sorting room the cranberries exit, to the right they are bulk loaded into cardboard boxes for fresh orders or large bins for the warehouse sales. If they exit to the left they are conveyed to the packaging machine, which weighs them into 1# portions which are then bagged and sealed and packed into boxes. (24 1# =1 case)
At one time all of the growers sorted berries with this method but as the times changed so did the methods of harvest. Nowadays only 5%-10% of the crop is harvested for fresh fruit use. There are only a handful of growers in Wisconsin that go the extra distance to put out a fresh hand sorted product. Alder Lake Cranberry is the only marsh in Manitowish Waters that has sorting rooms.
To ensure the highest quality our cranberries are sorted as needed for orders so they are always fresh!
