Fresh Coffee Tips - Keeping
Coffee Fresh
For the best fresh coffee the ideal tips are to obtain
unroasted beans, then roast and grind them on the same day that
you plan to brew.
Roasting coffee beans is, however, something of a specialty
and unless you are willing to invest in a fairly expensive
piece of equipment, the results are often less than
satisfactory. Even if you manage to master the art of coffee
bean roasting, it can fill the house with odours that take time
to dissipate and can even become annoying after a while.
Fresh Roasted Coffee Beans
Coffee beans, even after roasting, will stay fresh for a
while. Freshly roasted beans naturally release small amounts of
carbon dioxide which helps to keep oxygen away from the bean
whilst delaying spoilage. If stored in an airtight container,
especially with a drying agent, they will retain their good
flavor and aroma for up to a week.
Naturally, the closer to roasting they are ground and
consumed the fresher they will be. But even after a few days
they can still produce a stellar grind and a superior brew.
After two weeks the flavor may still be acceptable, even though
aroma will no longer be first rate. Whole bean coffee stored at
even optimum conditions will be dull after a month.
The key to getting a good fresh cup of coffee from purchased
roasted beans is to ensure that the skin is unbroken. Damaged
or broken skin will cause the oils underneath the skin and
inside the bean to deteriorate unless frozen, in which case the
brew will never be first rate.
Storing Coffee Beans
When storing coffee beans, be sure to use an airtight
container. A glass jar of the type used for instant tea grounds
is tempting, but totally inadequate as there is still too much
leakage around the lid. A good glass jar with a rubber seal is
best. Be sure to store the jar in a cool, dark place since not
only air, but also heat and light can contribute to spoiling
coffee beans.
Even better, but more expensive, are containers which flush
air with an inert gas, then inject the coffee beans which then
give off CO2, providing natural protection against spoilage.
Beans stored in this way can keep their freshness for several
weeks.
Coffee Bean Grinding
The next best thing to home roasting, and an option open
even to those with less than stellar cooking skills is grinding
at home.
Good grinders are available at moderate prices and are
generally easy to use and are not difficult to clean. Many are
automated to the point that with very minor experimentation, it
is possible to arrive at consistently good grinds.
Since grinding necessarily breaks the bean skin the same
'oil spoilage' problem can arise if the grind is not used
within a few days. Like roasted coffee beans, only more so, any
grounds not consumed within a day should be packed in a
desiccating cannister. Those cannisters contain a drying agent,
usually beneath a mesh at the bottom, that keep moisture from
introducing mold or excess oxygen into the grounds.
If not stored in a desiccating cannister, grounds will lose
much flavor within a few hours. Oils will evaporate and,
exposed to the air and moisture within the jar, the grounds
will deteriorate.
For a superior fresh coffee, grind only what you intend to
brew and drink everything brewed within an hour. With modern,
moderate cost machines there is no longer any reason to suffer
second rate coffee.
