Storing Coffee Beans
Storing Green Coffee Beans
Coffee must be stored in dry
and cool conditions. Exposure to the sun or moisture will
rapidly deteriorate the coffee. Storage in pergamino until
right before the shipping time will help preserve the coffee.
Burlap bas are often used for coffee bean storage because they allow air flow. They also preserve the coffee longer than plastic or paper bags.
Burlap bags should be aired on the patios before storing coffee
to prevent a baggy flavor or burlap scent from being imparted
to the coffee.
Coffee Seedlings Storage
Research in Kenya
has shown that coffee seeds are useful for over two years if stored
at 15°C at 41% moisture content in an airtight polythene bag
(Mitchell, 45 and Van der Vossen).
Roasted Coffee Storage
Whole bean coffee
maintains its freshness the longest. The freshness of ground
coffee will be lost in a matter of minutes since its protective
cellular structure has been broken and the volatiles have
been exposed to the environment to undergo oxidation. An
inert gas such as nitrogen can be used to help preserve
the whole beans for an extended time. Some people claim
that nitrogen could preserve coffee for up to two years,
but after a few weeks the coffee no longer acts, tastes,
nor smells like freshly roasted coffee. Whole bean coffee
that has been opened and exposed to the environment should
be kept for no longer than a week even if a vacuum seal
is in place. Coffee that has been roasted very darkly is even more susceptible
to oxidation and should be kept for an even shorter period
of time. Finally, there is a significant loss in crema development
for espresso coffee four days after roasting. Espresso coffee should be purchased
immediately after roasting and consumed within a couple
of days.
