Excerpt taken from Keurig Website
Each K-Cup® pack has a Best-Used-by-Date imprinted on the side. The Best-Used-by-Date is a guideline for optimal freshness recommended by the roaster, it’s not an expiration date. K-Cup® packs are nitrogen-flushed, sealed for freshness and impermeable to oxygen, moisture and light.
