1 00:00:00,120 --> 00:00:01,880 How long does popcorn last? 2 00:00:01,880 --> 00:00:06,200 Popcorn's shelf life varies depending on  its state—whether it's unpopped kernels,   3 00:00:06,200 --> 00:00:08,440 air-popped, or commercially packaged. 4 00:00:08,440 --> 00:00:13,400 Stored in a cool, dry place, unpopped popcorn  kernels can last indefinitely. However,   5 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. 6 00:00:18,040 --> 00:00:22,200 Once popped, air-popped popcorn can  last about 1 to 2 weeks if kept in   7 00:00:22,200 --> 00:00:25,600 an airtight container at room  temperature. Its freshness and   8 00:00:25,600 --> 00:00:29,280 crispiness will diminish over time,  so it's best enjoyed within a week. 9 00:00:29,280 --> 00:00:32,520 As to the commercially packaged  popcorn, the shelf life can vary   10 00:00:32,520 --> 00:00:36,200 widely depending on the type of packaging  and whether it contains preservatives. 11 00:00:36,200 --> 00:00:41,600 Generally, unopened, it can last 2 to 3  months past the printed date. Once opened,   12 00:00:41,600 --> 00:00:46,120 keeping it sealed and dry can extend  its freshness for a couple of weeks. 13 00:00:46,120 --> 00:00:52,040 Moisture is the enemy of popcorn, leading to  sogginess and potential mold growth. For all   14 00:00:52,040 --> 00:00:57,000 types, storing in a cool, dry place, away  from sunlight and in an airtight container,   15 00:00:57,000 --> 00:00:59,720 helps maintain its quality  and extends its shelf life.
