Storing Coffee

There has long been a debate as to the best way to store coffee. Green coffee is easy to store. Left in
a cloth bag in a cool, dark, dry place, g reen coffee will keep for a year with little difficulty. Placed in the
back of a kitchen cabinet away from the dishwasher or stove will probably be just fine for quite some time.
Cloth bags are best as they let the coffee breathe and they eliminate the possibility of condensation.
Roasted coffee is another matter all together. Once roasted the clock begins to tick. Whether kept in
the refrigerator, in air-tight bags, packed in nitrogen, or vacuum packed, roasted coffee changes chemi-
cally over time and soon becomes stale. The best advice is to keep fresh-roasted coffee in a closed, sealed,
glass container in a dark cool cabinet and try to use it relatively quickly. Fancy storage procedures like
vacuum packing or packing in nitrogen might be slightly helpful in the short run, but once exposed to air
the benefits these methods may provide are soon lost.
For drip, coffee is best used i n less than two weeks. For espresso, try to consume your roast within
no more than about one week to ten days. As you become accustomed to having fresh coffee you will be
able to easily taste the difference between freshly roasted coffee and that which has been stored too long.
The joy of home roasting is that you can roast as much as you need for about a week and never have to
taste stale coffee again.

Roasting Tips

As you be come more acquainted with the Hottop Coffee Roaster you will be bet ter able to judge
roast level and become more aware of how it affects the taste of the coffee. Here are some tips to help you
along:
If the roaster has not cooled sufficiently after the last roast cycle it will not be possible to start a new
cycle right away. If you attempt to restart the Coffee Roaster when it is too hot it will automatically go into
the cooling mode until the machine has cooled sufficiently. This is evidenced by the rotation of the agita-
tion arms in the cooling tray and the fans runn ing.
When the machine has reached the appropriate temperat ure, it will start beeping to signal you that
it is time to add the coffee as described earlier. At this time you can proceed by fill ing the machine with
beans, and continue a normal roasting cycle. This protects the machine from overheating and the beans
from being scorched by being added to a too-hot drum.
A lot of factors can affect the roast level of the coffee but there are some things you can do to fine-tune
your roast. If the roasted coffee comes out too light try using a longer cycle (Create a longer program for
the KN-8828P, program more time into the KN-8828D or KN-8828P in AUTO mode, or use a higher roast
number on the KN-8828). You can also reduce the batch size to 225 grams of beans. If, on the other hand,
the roasted coffee comes out too dark , try increasing the batch size to 270 grams or decreasing the roast
time. Experiment with different roast times and batch sizes to find the taste that you like and the amount
of coffee you can use before it begins to lose flavor.
If a batch of coffee is ejected ac cidently during the roast but is not dark enough it is best to discard
the beans. Coffee goes th rough a chemical process during the roasting cycle and this reaction cannot be
repeated- you get one chance. It would be like trying to unscramble, then re-scramble an egg. It just can’t
be done.

Dark and Decaf Coffee

Be careful when roasting very dark. When you reach second crack, the cracks fi rst increase in pace,
become quite active, then decrease again. If you hear the frequency and number of the cracks during sec-
ond crack begin to slow down it is a warning that must not be ignored. The beans are about to be bu rnt,
and if the roasting is not stopped, it may become a serious fire hazard in a shor t time. Learn to listen for
the cracks and use them to help you achieve perfect roasts.
