Nespresso capsules are hermetically sealed to protect the coffee inside from light, moisture and oxygen. At the end of every Nespresso coffee sleeve you will find both the “Production date” and the “Best before” date. The “Best Before” date is approximately 12 months from the date of production. As the “Best before” date simply acts as an indicator of optimal freshness, flavour and aroma, unopened capsules are completely safe to consume after this date.
