How Long Is Strawberry Jam Safe to Eat?
How long does strawberry jam stay fresh?
Strawberry jam stays safe and high quality in the refrigerator for up to 1 year.
Preserving the vibrant flavor of summer berries is the primary purpose of jam. Because of its high sugar content and low moisture level, strawberry jam is quite shelf-stable. However, once a jar is opened, it is exposed to air and potential contaminants, which can lead to mold growth or fermentation over time. Proper refrigeration is essential to maintain its texture and safety after the seal is broken. While the sugar acts as a preservative, environmental factors like humidity and temperature play a significant role in how long your favorite spread remains delicious.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
