Coffee Brewing Methods
Once upon a time there was only the lowly
Coffee percolator. Coiffed housewives
would sit lovingly staring at water being heated until
pressure forced it up a small tube and over a basket full
of grounds.
Well, it was amusing to watch even if the coffee couldn't be
very good. Boiling coffee and running the liquid over grounds
more than once can each produce a brew less than ideal.
Then in the 1970s, as with so many things, life changed
forever. The drip method - inexpensive, quick and even an
improvement in taste - came to dominate the scene. A cup of
grounds thrown in a plastic container over filter paper, a few
minutes of nearly boiling water dripping over the result and -
voila!, coffee in a glass pot.
Later came pre-packaged 'pods' of a favorite blend, changes
in materials and all sorts of controls to adjust the brew, and
internal spouts that spread the water evenly over the grounds.
Whether cone or flat, always near 200F (93C), please.
In the '90s, Espresso makers became the
rage, with the importation of European culture and the
application of American ingenuity to lower the cost without
ruining the flavor. Hot water is forced under pressure through
finely ground dark roast and in a few minutes, out pours a
delicious, aromatic drink.
Add steamed, frothy milk and you have a cappuccino or latte,
depending on the ratio of milk to coffee. A definite
improvement and the variety of espresso makers makes for
delightful experiments in chemistry.
The French plunger is another device aiding
the spread of European methods, anywhere open-minded coffee
innovators are seeking the new. A metal rod extends through the
center of a glass cylinder, where it is topped with a handle.
At the other end is a filter, fitting snugly inside the
container.
Put grounds into the container and pour nearly boiling hot
water in. Unlike the drip method, the grounds steep until the
plunger is pressed. The result is a dark, full-bodied brew
served right from the device.
One of the more esoteric brew methods uses the
Vacuum brewer: two glass or metal bowls, one
atop the other. Heat causes water to rise into the upper,
similar to the percolator principle. Remove the heat and as the
liquid cools slightly a partial vacuum is created, drawing the
hot water through the grounds and into the lower chamber.
The process is a pleasant show at a dinner party and a
wonderfully fresh cup, since it can be carried out right at the
table.
Of course, none of these methods is really new - most go
back centuries in one form or another. The Ibrik from Turkey
may be one of the oldest. Water is heated in a brass or copper
container with a long handle and a grooved tongue. Finely
ground coffee is added directly to the hot water and then
poured, unfiltered.
Any of these will produce a delicious cup, but all bring out
distinctive aspects of the ground. Try them all! You may find
that a history lesson can also be a delectable taste tour.
