How long does popcorn last?

00:00:01.880 --> 00:00:06.200
Popcorn's shelf life varies depending on 
its state—whether it's unpopped kernels,  

00:00:06.200 --> 00:00:08.440
air-popped, or commercially packaged.

00:00:08.440 --> 00:00:13.400
Stored in a cool, dry place, unpopped popcorn 
kernels can last indefinitely. However,  

00:00:13.400 --> 00:00:18.040
for optimal taste and popping efficiency, 
it's best to use them within 1 to 2 years.

00:00:18.040 --> 00:00:22.200
Once popped, air-popped popcorn can 
last about 1 to 2 weeks if kept in  

00:00:22.200 --> 00:00:25.600
an airtight container at room 
temperature. Its freshness and  

00:00:25.600 --> 00:00:29.280
crispiness will diminish over time, 
so it's best enjoyed within a week.

00:00:29.280 --> 00:00:32.520
As to the commercially packaged 
popcorn, the shelf life can vary  

00:00:32.520 --> 00:00:36.200
widely depending on the type of packaging 
and whether it contains preservatives.

00:00:36.200 --> 00:00:41.600
Generally, unopened, it can last 2 to 3 
months past the printed date. Once opened,  

00:00:41.600 --> 00:00:46.120
keeping it sealed and dry can extend 
its freshness for a couple of weeks.

00:00:46.120 --> 00:00:52.040
Moisture is the enemy of popcorn, leading to 
sogginess and potential mold growth. For all  

00:00:52.040 --> 00:00:57.000
types, storing in a cool, dry place, away 
from sunlight and in an airtight container,  

00:00:57.000 --> 00:00:59.720
helps maintain its quality 
and extends its shelf life.
