Maple syrup is among the first locally harvested food products available in Michigan farmers markets each spring. According to the Michigan Maple Syrup Association (n.d.), Michigan ranks fifth nationally in maple syrup production at about 90,000 gallons annually. It takes approximately 40 gallons of maple sap to make one gallon of maple syrup.
One-hundred-percent pure maple syrup tastes very different from the pancake syrups found in most grocery stores. These pancake syrups consist mostly of corn syrup or cane sugar. They may contain either no pure maple syrup or pure maple syrup in very small amounts. Be sure to read the label of ingredients if you are looking for pure maple syrup.
Nutrition
One tablespoon of maple syrup has about 50 calories. Maple syrup is approximately 67 percent sugar and 33 percent water. The sugar in maple syrup is sucrose (88 to 89 percent) with small amounts of glucose and fructose sugar (11 to 12 percent). White sugar is also sucrose. According to the Ohio State University Extension (2009), there is no direct scientific evidence that maple syrup is healthier than white sugar. Diabetics and others who are limiting their sugar intake need to treat maple syrup as they do other sugar products.
Storage
Store pure maple syrup in the refrigerator – even if the bottle has not been opened. Pure maple syrup in glass or tin containers may be stored in the refrigerator for up to one year. Use syrup stored in plastic containers within three to six months. Plastic breathes causing a change to syrup color and flavor (Ohio State University Extension, 2009).
You may freeze maple syrup. To freeze, pour it into freezable glass jars, making sure to leave a one-inch space at the top. Frozen syrup maintains quality and flavor for an indefinite period.
Selection
The characteristic flavor of maple syrup includes sweetness from the sugars, a slight tartness from the acids, and a range of aromas that includes vanilla, coffee and chocolate. The longer the syrup is boiled, the darker the color (University of Vermont, n.d.).
All states must use the U.S. Department of Agriculture color standards to grade, or classify, maple syrup based on color, flavor and sugar content. However, states may use their own words to describe color. Grade A refers to the lighter, more delicately flavored, sometimes less concentrated syrups, which people pour directly on food. Grade B, more often used for cooking, is stronger in caramel flavor. Maple syrup grading kits are available at specialty stores or through online retailers. Maple producers use them to help classify their syrup for quality control. (University of Vermont, n.d.). 2
Michigan maple syrup has four grades: Grade A Light Amber, Grade A Medium Amber, Grade A Dark Amber, and Grade B. The Michigan Maple Syrup Association (2005) says Grade A Light Amber has a delicate maple taste and extra light amber color; Grade A Medium Amber has a mild maple taste and light amber color; Grade A Dark Amber has a hearty maple taste and a medium amber color; and Grade B, good for cooking, has a robust maple taste and dark amber color.
Production
Maple syrup is typically harvested from sugar maple and black maple trees. Even though other tree varieties can produce sap for syrup production, these two varieties typically provide the sweetest sap. A maple tree needs to be about 40 years old and at least 32 inches in circumference at 4.5 feet off the ground before tapping.
Maple sap is harvested as a slightly sweet, colorless liquid. Sap is boiled so the water in the sap evaporates and the sugars become concentrated. Sap harvesting can start as early as February in southern Michigan and go until April in the north. The Michigan Maple Syrup Association (n.d.) estimates that only about 1 percent of Michigan’s maple forest resources are utilized for syrup production.

Maple Baked Beans
4-6 servings
Ingredients:
2 cups dried navy beans (You may want to look for Michigan navy beans.)
6 strips bacon.
1 onion, chopped.
1 teaspoon dried mustard.
1 teaspoon salt.
1/2 cup pure maple syrup (Grade A or Grade B ‒ your choice.)
1 pork hock, fresh or smoked.
2 tablespoons butter.
2 tablespoons brown sugar.
Preheat over to 325 °F. Simmer navy beans in water until tender, about 20 minutes. Drain beans and reserve liquid for cooking. Line bean pot with strips of bacon. In a large bowl, toss together onion and beans. In another bowl, combine 2 cups bean cooking liquid, mustard, salt and maple syrup. Place half the bean mixture on bacon strips in pot. Place pork hock on beans, top with rest of bean onion mixture, then pour over reserved cooking liquid/ syrup mixture. Cover with lid and place in oven for 3 hours, or until pork hock is fully cooked and pulling away from the bone. If beans begin to look dry, add more cooking liquid.
Once pork hock is cooked, remove beans from oven and remove lid. Mash together butter and brown sugar into a paste, scatter sugar paste over beans and place back in the oven, uncovered, for an additional 30 minutes. Remove from oven and serve.
