Brewing Coffee
No matter what they're called, all ways of brewing coffee are basically
the same: The ground coffee is soaked in the water until the water tastes
good. The only equipment you really need to make great coffee is an open
pot, a flame, and, possibly, a strainer.
There are many ways of brewing
coffee. The Key Factor in brewing coffee is the extraction time , the
contact time between hot water and the grinds, and the water
temperature. Each brew method extracts the aroma and flavours of coffee
differently.

Brewing Suggestions
No matter which method or invention you use to brew your coffee, most
authorities urge you to do the following:
- Grind the coffee as fine as
you can make it without losing any through the holes in the filter of
the coffee maker. Never grind it to a powder.
- Use plenty of coffee: unless
your coffee maker instructs otherwise, at least 2 level tablespoons or
1 standard coffee measure per 6-ounce cup.
- Keep the coffee maker clean,
and rinse it with hot water before you brew.
- Use fresh water, as free of
impurities and alkalines as possible.
- Brew with hot water, as
opposed to lukewarm or boiling water. Boiling damages coffee flavor
because it vaporizes much of the coffee essence while it continues to
extract other bitter chemicals. A temperature of 200 degrees F
is ideal, which means bringing the water to a boil and then waiting a
couple of minutes before brewing.
- In filter and drip systems,
avoid brewing less than the brewer's full capacity. If the pot is made
to brew six cups, the coffee will taste better if you brew the full
six.
- If you live in an area with
alkaline, or hard, water, periodically run a strong solution of
vinegar through the works of your brewer to clear out lime deposits,
and rinse thoroughly.
- Some don'ts: Don't boil
coffee; it cooks off all the delicate flavoring essence and leaves the
bitter chemicals. Don't percolate or reheat coffee; it has the same
effect as boiling, only less so. Don't hold coffee for very long on
the heat for the same reason. Don't mix old coffee with new; it's like
using rotten wood to prop up a new building.
- Ninety-nine percent of a cup
of coffee is water. If the water isn't pleasant to drink, don't make
coffee with it. Hard, or alkaline, water does not directly harm flavor
and aroma, but does mute some of the natural acids in coffee and
produces a blander cup without the acidy snap. Water that has
been treated with softeners makes even worse coffee. Use bottled water
or a filter system.
