There are many methods for brewing a fine cup of coffee -- no single technique is right for everyone. The method you choose for brewing your coffee should be based on your needs and your unique coffee preferences. Do you want a hearty mug of coffee for breakfast? An afternoon cappuccino? Or a dessert espresso? Do you prefer a milder coffee or a more robust coffee flavor?
But no matter how you choose to brew your coffee, there are guidelines
to follow which will give you the best cup of coffee possible. To optimize
the quality of every cup of coffee you prepare, fine-tune your brewing
routine by incorporating these suggestions.
The Coffee
If you purchase whole bean coffee, always grind your beans as close to the brew time as possible. Use a burr coffee grinder so the grind size is consistant. A blade grinder is less preferable because some coffee will be ground more finely than the rest. Do not underestimate the importance of the size of the grind to the taste of your coffee. If your coffee tastes bitter, it may be overextracted, or ground too fine. On the other hand, if your coffee tastes flat, it may be underextracted, meaning that your grind is too coarse. With a burr coffee grinder you can set the grind size to match you tastes.
Whole beans should be kept in an airtight container and stored in a cool, dry place.
Never reuse your coffee grounds. Once brewed, the desirable coffee flavors
have been extracted and only the bitter undesirable ones are left.
The Water
The water you use is VERY important to the quality of your coffee. Use
filtered or bottled water if your tap water is not good or imparts a strong
odor or taste, such as chlorine. If you are using tap water let it run
a few seconds before filling your coffee pot. Be sure to use cold water.
Do not use distilled or softened water.
Ratio of Coffee to Water
Use the proper amount of coffee. A general guideline is 2 tablespoons
of ground coffee for every six ounces of water. This can be adjusted to
suit individual taste preferences. Be sure to check the 'cup' lines on
your brewer to see how they actually measure.
Water Temperature
Your brewer should maintain a water temperature between 195 - 205 degrees
Fahrenheit for optimal extraction. Colder water will result in flat, underextracted
coffee while water that is too hot will also cause a loss of quality in
the taste of the coffee. If you are brewing the coffee manually, let the
water come to a full boil, but do not overboil. Turn off the heat source
and allow the water to rest a minute before pouring it over the grounds.
Brewing Time
The amount of time that the water is in contact with the coffee grounds
is another important factor affecting the taste of your coffee. In a drip
system, the contact time should be approximately 5 minutes. If you are
making your coffee using a plunger pot, the contact time should be 2-4
minutes. Espresso, as the name implies, means that the brew time is short
- the coffee is in contact with the water for only 20-30 seconds. If the
taste of your coffee is not optimal, it is possible that you are either
overextracting (the brew time is too long) or underextracting (the brew
time is too short) your coffee. Experiment with the contact time until
you can make a cup of coffee that suits your tastes perfectly.
Enjoy Your Coffee
Brewed coffee should be enjoyed immediately! Brewed coffee begins to lose
its optimal taste moments after brewing so only brew as much coffee as
will be consumed immediately. If it will be a few minutes before it will
be served, the temperature should be maintained at 180 - 185°F. It should
never be left on an electric burner for longer than 15 minutes because
it will begin to develop a burned taste. If the coffee is not to be served
immediately after brewing, it should be poured into a warmed, insulated
thermos and used within the next 45 minutes.
