SISTER BAY, WIS. - Walk into Cherry Republic's store in the heart of the nation's biggest tart cherry-producing region, and you could end up with jam or salsa with fruit that had to be imported from Poland.
Cherry Republic can't get enough tart cherries from its local orchards because 97 percent of Michigan's crop was destroyed this year by an unseasonably warm March that caused trees to bud was followed by an April freeze that killed the blossoms.
Trees in New York and Wisconsin, which have smaller but significant tart cherry harvests, suffered the same damage.
Prices usually skyrocket when farmers take that kind of a loss, or, in severe cases, consumers might just have to give up on a fruit for a season. But cherry processors are scrambling to get what fruit they can, sometimes from Poland or Turkey, and taking a financial hit in an effort to keep prices low.
Tart cherries are different from sweet cherries, the variety sold fresh at farmers markets and in grocery stores. Most tart cherries are dried or canned and used as ingredients in pies, granola and trail mix. While sweet cherries are mainly grown on the West Coast, 70 percent of the nation's tart cherries come from Michigan.
The problem for tart cherry growers and the companies that dry or can the fruit is that it can be easily replaced by cranberries, blueberries or raspberries -- and each group of fruit growers has its own industry marketing group ready to capitalize on the others' failures.
When tart cherries had a poor harvest in 2002 and dried cherry prices went up, companies that make granola, scones and other foods substituted other fruit, said Terry Sorenson, the president of the Wisconsin Cherry Growers Association.
"It took us a long time to bring sales back after 2002. That's definitely a concern this year," he said. To avoid a repeat, the cherry industry will try to keep its prices as stable as possible this year. Companies hope to make a profit, but if not, to at least keep their customers.
