Cape Cod is known for its locally produced jams and jellies. Growing among the sand dunes of Cape Cod is the beach plum, which ripens in the late summer and early fall. Beach Plum Jam is the most unique and sought after jam on the Cape. This unique treat comes in a 10 ounce jar and is made in small batches from beach plums, sugar, pectin and citric acid. There are also a wide variety of other delicious Cape Cod produced jams and jellies also available at The Brewster Store and listed in this section of our web site. There is a minimum purchase of three jars.
