Clearbrook Farms has been making their preserves since 1942 the old fashion way. Taste the full natural flavor of wild blueberries collected in Maine and preserved with minimal sugar. If you love blueberries these will definitely surprise and delight your taste buds. They've been packing their fruit-filled preserves in these classically elegant jars for more than 30 years. These French canning jars have been used for over a century to preserve the flavor of food and keep the contents from spoiling. After you have finished the preserves the glass jars can be used for leftovers, sauces, paper clips or even a small bunch of flowers.
