vacuum packed coffee - best practices PDF Print E-mail


How long can you keep opened vacuum packed coffee?  How long does vacuum packed GROUND coffee last?  How long will vacuum packed coffee BEANS last? 

To take the guess work out of it for you, I've done a bit of research and have come up with a few suggestions for you, below are the results.  Feel free to add your own 'best practises' by add a comment at the end of this article.


Ok, if you've opened the pack your coffee will last in the ...

PANTRY:  one - two weeks

Freezer:  one month


After this time the coffee quality will of course to deteriorate, but will probably still be safe to drink.  


Coffee bean's two greatest enemies are air and moisture. Ideally, coffee should be ground, brewed, and consumed quickly to obtain the best flavor.  Coffee beans are at their peak within 24 to 72 hours after roasting and begin to quickly stale after that (within a week, most of the original flavor will have deteriorated). It is best to buy 

 fresh-roasted coffee in quantities that you will use within 7 to 10 days. Whole Coffee Beans - Should be stored in an airtight container in a dry dark, place at room temperature. they will be at their best for about a month after they are roasted (most fine coffees are roasted just before they are sold).


Ground Beans - Ground beans don's stay fresh as long as whole beans because more surface area is exposed. Keep ground beans in an airtight container in a a dry dark, place at room temperature for approximately two weeks.


Vacuum-Pack Coffee - Coffee that is sold in vacuum-packed tins has had oxygen and carbon dioxide removed, a process that keep the coffee fresh. Once the can is opened, the coffee will be in its prime for 7 to 10 days.


Freezing or Refrigerating Coffee Beans - It is generally not recommended to store coffee beans in the freezer or refrigerator. The enemies of coffee are extreme temperatures (hot or cold), air, light, moisture, and strong odors.


Having  just said that the freezer is not a good idea for storing coffee, one article I read suggested that the freezer is acceptable only for a time. What this means is, that once you take it out of the freezer, it should never go back in. Condensation can form and adversely affect taste, as the frozen moisture on your coffee will melt and be absorbed into the bean, which deplete the flavorful oils.  The longest you could expect your coffee to last in the Freezer is a month for whole beans, and 1-2 weeks for ground.


  Best results are obtained by transferring the coffee from the packet and putting it in a airtight container.


The 'Best by', 'Use by' and 'Best before', dates on coffee packets are placed there by manufacturer's and is their best estimate of  who long the coffee will stay at it's peak.  It is unsually quite safe to use the coffee after these dates have expired.
