Maple syrup has a unique flavor that sets it apart from other specialty foods. Its characteristic for exhibiting different subtle flavors depending on where it was produced, and, at times, how it was produced make it a product that everyone, regardless of their taste preferences, can enjoy. However, this characteristic also makes syrup flavor susceptable to flavors that are not conisdered typical. These off-flavors can occur anywhere from the tree to the containers. Not only do production methods affect the flavor, but Mother Nature has a hand in it too. Following are some common off-flavors that have been encountered, their likely causes, and ways to avoid these problems.
