How long does popcorn last?
Popcorn's shelf life varies depending on its state—whether it's unpopped kernels,
air-popped, or commercially packaged.
Stored in a cool, dry place, unpopped popcorn kernels can last indefinitely. However,
for optimal taste and popping efficiency, it's best to use them within 1 to 2 years.
Once popped, air-popped popcorn can last about 1 to 2 weeks if kept in
an airtight container at room temperature. Its freshness and
crispiness will diminish over time, so it's best enjoyed within a week.
As to the commercially packaged popcorn, the shelf life can vary
widely depending on the type of packaging and whether it contains preservatives.
Generally, unopened, it can last 2 to 3 months past the printed date. Once opened,
keeping it sealed and dry can extend its freshness for a couple of weeks.
Moisture is the enemy of popcorn, leading to sogginess and potential mold growth. For all
types, storing in a cool, dry place, away from sunlight and in an airtight container,
helps maintain its quality and extends its shelf life.
