INTRODUCTION
The goal of this
document is to steer
people through the
obstacle course that is
brewing a great cup of
coffee. We understand
full well what it is
like when the alarm goes
off at 6:00 AM and you
have to hit the road at
6:35, but you want a
good, hot cup of coffee
in your hand when you
do.
Chances are, you could
be brewing coffee in a
way that delivers
flavors far superior to
what you are getting
now... in the same
amount of time or less.
To decide which brewing
method or methods best
match your needs, start
by asking yourself these
questions:
-
On what occasions do
I normally drink
coffee? What is the
relative importance
of taste and
convenience? (You
may have more than
one answer: for
workday mornings vs.
leisurely
entertaining, for
example.)
-
How much money am I
willing to spend on
brewing equipment?
On coffee?
-
Can this brewing
method brew
great-tasting
coffee?
For most coffee
drinkers, the biggest
hurdle to overcome as
you begin getting
serious about coffee is
the fact that you own an
electric drip
coffeemaker, and the
vast majority of
electric drip brewers
sacrifice taste for
convenience. What we
humbly suggest, if good
taste is your goal, is
an investment of
attention rather than
dollars. Grinding fresh
and measuring coffee
precisely becomes second
nature after a week. If
you are going to the
trouble of sourcing
fresh, optimally roasted
beans, brew to capture
every precious nuance of
flavor and aroma you're
paying for.
We
define great brewing
methods as those that
meet all the criteria,
the "essential elements,
" we have just discussed
for brewing a great cup.
(Remember that your
familiarity with the
essential elements of
great coffee gives you
the tools to evaluate
any brewing method,
too.) There are several
great methods that,
while a bit more
"hands-on" than
automatic methods, brew
monumentally better
coffee in considerably
less time. These manual
brewers are also simple,
easy to use and
maintain, and
inexpensive.
We
will focus on three
brewing methods that
offer the highest
possible cup quality:
the manual drip coffee
maker, the coffee press
or plunger pot, and the
vacuum pot.

Drip Brewing
Great drip coffee
combines the essential
brewing elements in a
very specific way. You
need a filter that
contains a heaping
measure of fresh grounds
for each 6 ounces of
brewer capacity, and
water heated to 195-205°
F. The water should
saturate the grounds
thoroughly and gently;
the total brew cycle,
start to finish, must
take 4-6 minutes. If it
takes more than 8
minutes, the coffee will
be over-extracted.
This sounds relatively
simple, and is-as long
as you are brewing
coffee by hand, in a
manual drip maker. (It
is also relatively easy
to accomplish if your
kitchen is equipped with
a $1,000, plumbed-in
commercial brewer, but
that's a different
story.) It is all but
impossible to brew drip
coffee that meets the
above criteria using
typical home electric
brewers, and herein lies
the source of the
frustration so many
coffee lovers encounter
when they try to
duplicate good
coffee-bar coffee at
home.
"Automatic drip" brewers
are exactly what their
name suggests: an
attempt to automate
something that was
originally done by hand.
By taking a detailed
look at the process you
are trying to automate,
it becomes much easier
to understand why most
home electric brewers
make such poor coffee.
For this run-through, we
will use the specific
manual drip setup we
rate as the best.
However, similar effects
can be achieved with
other brands and
components.
[back to
index]
Our Manual Drip Method
To
brew manual drip coffee,
we start by bringing a
quart of fresh, cold
water to a boil. The
easiest way to do this
is to use an electric
kettle, which heats
water much faster than a
burner or microwave. The
inexpensive Rival brand
kettle we use happens to
have a 1-quart capacity
which matches the
container we brew into
precisely; many other
brands have similarly
convenient markings.
While the water heats,
we assemble the brewer
and grind our beans. We
brew directly into a
quart-size Nissan
thermos using a matching
filter cone (made by the
same company). This
thermos is made entirely
of stainless steel and
insulates with a vacuum
layer, so there's no
fragile glass liner. The
filter cone is made to
use a #4 size paper
filter, but we cheat a
bit and upgrade to a #6.
This provides a little
extra height for the
grounds to expand as the
water first moistens
them. The additional
room is invaluable when
brewing recently roasted
or especially
low-density coffees,
which froth and swell
significantly during
brewing. The entire
cone/thermos combination
costs about $45.
Grinding and measuring
are also made easy by
choosing this particular
size. Our very typical
blade grinder contains
about 2 ounces of coffee
when filled to
capacity-perfect for the
1-quart "pot" were
preparing. Because the
coffee brews in about 4
minutes, we grind our
beans for 25 seconds and
dump them in the filter
cone. When the water has
reached a boil, the
kettle whistles. We
pause for a beat to
achieve the
just-off-boil
temperature range, then
wet the grounds with
water. They quickly rise
to form a cap. After a
few seconds, the cap
settles, and we pour
more water over the
grounds. Each time the
water level in the
filter lowers, we pour
more-until our kettle is
completely empty. Sure
enough, the pouring
process lasts about 4
minutes. Our fragrant,
steaming, and delicious
pot of coffee is done.
[back to

Manual vs. Automatic
Drip
In
our extensive testing of
home automatic brewers,
no model under $150 came
close to producing
coffee of the quality we
brewed with our manual
method. Even the best
commercial units do no
better. Why is this so?
Using the manual method,
we bring all the water
to the correct
temperature before
brewing. The physics of
heating with residential
wattage make this all
but impossible for most
home electric
coffeemakers-especially
when a large part of the
available juice is
dedicated to heating the
burners that are
supposed to keep brewed
coffee hot. Most units
can't get water above
the mid-180°F range,
which is nowhere near
hot enough for optimum
flavor extraction.
Next, our open-top cone
and oversized filter let
us use the proper amount
of coffee. Virtually no
home electric brewer
holds close to the
correct amount. Even
upscale models cater to
mass-market preferences:
a weak pot, with stale
coffee (so no degassing
is expected). To obtain
decent results, you have
to "short" the pot-use
less water-or start
cleaning when the messy
grounds overflow.
Finally, our brewing
process takes 4 minutes.
A typical electric unit
takes 11 or 12 minutes.
When the grounds and
water stay in contact
for more than 8 minutes,
the result is
over-extraction; as you
know, the coffee will be
bitter. Commercial drip
brewers meet the
critical 195-205°F
temperature and 4-6
minute brew cycle
requirements, but home
electrics don't. This,
in a nutshell, is why
you can't make
"professional" coffee
using one of these
machines.
With all the bells and
whistles coffeemakers
boast, why are the
fundamentals so poorly
attended to? We asked
this question of a
designer responsible for
many of the best selling
home electric models.
"This is a volume
business," he replied,
"we sell thousands and
thousands of each
design. The criteria are
simple: They have to
sell-profitably-for
$49.95 or less. We build
them to be thrown out
within eighteen months
of purchase, because
that's what lots of
people do; they throw
these out rather than
giving them a good
cleaning.
"Besides, the machines
work just fine according
to Consumer Reports. But
don't ask me. I don't
drink coffee."
If
you love great drip
coffee (as we do), the
biggest favor you can do
yourself is to unplug
your electric model and
brew by hand. At
present, there is just
one alternative: the
Dutch-made Technivorm,
which is the only home
electric that brews to
professional standards.
These makers start at
about $150. They aren't
cheap, but when you
weigh their ability to
brew excellent coffee
over decades against
replacing a less
expensive brewer every
few years and suffering
through mediocre coffee
all the while, you may
conclude that the
investment is
worthwhile.
For those who are really
willing to compromise~
we will relent slightly
and mention two other
models. The Rowenta
thermos brewer (about
$75) is capable of
brewing a decent cup,
providing the roast is
relatively light (darker
roasts and super-fresh
light ones will overflow
the brew basket). The
brew temperature is only
a few degrees short of
ideal, and the
glass-lined carafe does
a good job of retaining
heat and aroma. Brew
time is over 8 minutes,
so adjust by using a
medium- rather than
fine-cone filter grind.
The Bunn Home Brewer,
which is widely
available through
discount retailers for
just under $50, comes
closer to duplicating
commercial machine
performance than any of
the upscale department
store brands. Its brew
cycle is actually too
short (3-1/2 minutes)
and it won't hold a full
dose of fresh coffee.
But if you cut the water
to a quart and use a
rather fine drip grind,
you end up with decent
drip coffee. Because the
Bunn brews into a glass
pot on a burner, you
need to drink the
finished coffee right
after brewing.

On Filters
The advantage of using
paper filters is the
complete clarity of the
finished brew. Its body
is relatively light, and
the coffee remains
palatable longer than
that of any other
method. We recommend the
"oxygen-whitened"
(non-chlorine-bleached)
variety; bleaching is an
environmental no-no,
while brown, unbleached
filters can impart a
woody taste to the brew.
You can reduce the paper
taste of any filter by
rinsing it with a little
good water before you
fill it with ground
coffee.
Gold-washed filters have
the great advantage of
lasting for months, even
years, if gently
hand-washed. These
filters are made of fine
mesh lightly coated with
gold, which prevents
coffee oils from
clinging better than any
other metal. Gold-washed
filters leave a higher
concentration of
sediment and flavorful
oils in the finished
brew; the coffee is
slightly more intense,
the pot life somewhat
shorter. We find these
trade-offs
worthwhile-besides, the
grounds easily emptied
from these filters make
great compost.
[back to
index]
THE COFFEE PRESS
Many people have seen a
coffee press, but it's
astonishing how few have
actually used one-and
how impressed coffee
lovers are, once they
try the coffee pouring
out, with its taste. The
coffee press, or plunger
pot, is simple, elegant,
and hands-down the
easiest way to make good
coffee. Pour fresh
boiled water over medium
to coarsely ground
coffee, then allow it to
infuse for about four
minutes. Press the
plunger's stainless
steel filter down
through the infusion,
and you get a very
thickly textured cup
that is full of natural
coffee oils.
The sediment produced
with the coffee press is
an acquired taste for
some. The modest
pressure you use to
plunge at the tail end
of brewing accentuates
the perceived acidity of
a coffee, making this an
especially good choice
for low-acid Indonesians
and darker blends.
Pressing, incidentally,
is the most flavorful
way to brew decaf. Once
you try it, you will
never go back.
Coffee-press coffee
should be consumed
within 20 minutes of
preparation. Because the
oils and particles in
the finished brew
continue to extract even
after plunging,
decanting the contents
of a coffee press into a
thermos for longer
storage is not
recommended.
[back to

THE VACUUM POT
Few people these days
have even seen, let
alone used, a vacuum
pot. Vacuum-pot brewing
represents the ideal for
which drip brewing is a
convenience-oriented
compromise. The setup
looks a bit unwieldy and
quite fragile, but it
was the method of choice
in diners and
restaurants across the
country through the
early 1950s. Today,
vacuum pots are found
mainly in high-end
Japanese coffee houses
and at home with
in-the-know coffee
connoisseurs.
The brewer looks
something like an
hourglass. Water comes
to a boil in the bottom
bowl, while the grounds
sit in the top. The
boiling action pushes
the water upstairs to
mix with the grounds,
where it infuses at
just-below-boiling
temperatures for three
minutes. You must then
move the whole thing
away from the heat, at
which point a vacuum
develops in the lower
bowl as a result of its
slight cooling.
This vacuum draws the
brewed coffee down. Once
it's all there, get
ready to enjoy it. Like
drip coffee, the
finished brew is almost
perfectly clear-but with
absolutely no influence
from paper filters. It
also pours out piping
hot, more so than coffee
made by any other
method. The entire
process takes about six
minutes after the water
is hot, and once
underway needs no
tending beyond a
watchful eye.
In
the words of food expert
Corby Kummer, the vacuum
pot is truly "the CD
player of coffeemakers:
all you taste is the
coffee." Because of its
fragility and seemingly
cumbersome nature, the
vacuum pot is probably
destined to occasional
or weekend use, at least
by all but the most
hardcore consumers. But
if you cherish coffees
that are bright or
aromatically complex, or
never can seem to get
your coffee hot enough,
you may find a vacuum
brewer to be a very
rewarding investment.

MISCELLANEOUS METHODS
Flip-Drip or Neapolitan
This oddly shaped brewer
is made up of two little
pots joined in the
middle by a two-sided
strainer. You heat water
in one side of the pot,
then flip the whole
apparatus over-
whereupon the coffee
drips through the
strainer into the empty
side. These are fun
little jobs, but most
are made of aluminum,
which is not desirable
for coffeemakers (coffee
oils eat away at the
metal-not particularly
good for your health or
the brewer's). The cup
style is similar to, but
invariably cooler than,
manual drip brewed with
a gold-washed filter
right into a thermos.
Cold-Water Concentrate
This brewing method is
offered by two
manufacturers, Filtron
and Toddy. To brew
cold-water coffee, you
use the coffee maker to
steep a pound of coffee
overnight, then filter
the result through nylon
mesh disks. The
resulting concentrate
must be stored in the
refrigerator, and keeps
well for a week or two.
Hot coffee is made by
mixing small amounts of
the concentrate with hot
water, cold coffee by
mixing with cold water.
Cold-water brewers are
marketed as being ideal
for those in search of
"low-acid" coffee, and
they do remove some of
the slight acidity
coffee possesses. Since
all coffee is low in
acidity, however,
"low-acid" in this case
seems to be used as the
equivalent of "mild."
Because cold water
doesn't extract much
flavor from coffee, the
best way to get a
flavorful extract is to
use a blend with more
kick than you might seek
otherwise. One
ferocious-sounding
favorite is half Sumatra
and half French roast;
out of a cold-water
brewer, this tastes
pretty
middle-of-the-road.
Another good choice is a
straight Ethiopian
Harrar or, if you're
feeling flush, Yemen
Mocha; their fruity high
notes come through
surprisingly well.
Relative to the instant
coffee that comes from a
jar, "instant" cold
water coffee is manna
from heaven. Compared to
great coffee brewed with
hot water, however, it's
just instant coffee.
[back to

Middle Eastern Coffee
Aficionados of this
ancient brewing method
are probably the only
coffee drinkers who
would characterize
straight espresso as
being a bit too mild or
lacking in body! To make
it properly, you need
the right tools: a
conical copper or brass
pot known as an ibrik, a
special grinder that
looks like-and is
occasionally sold as-a
pepper mill, and the
smallest demitasse cups
you can find.
The coffee must be
freshly ground and needs
to be powder fine. Blade
grinders won't do the
job, and neither will
most commercial units.
Use the pepper mill
type, or a mortar,
pestle, and lots of
elbow grease..
The ibrik should be
filled less than half
full in order to allow
enough room for the
coffee to froth and
expand. Figure
proportions by measuring
2 teaspoons of grounds
and 1 of sugar per
demitasse of water; you
can adjust the amount of
sugar to taste over
time. Since this method
involves boiling and
drinking the grounds, a
substantial amount of
sugar is used to keep
bitterness in check.
Cardamom is often added
as well, ground with the
coffee at a casual ratio
of one seed (seed, not
pod) per demitasse.
Bring the mixture to a
boil over medium heat,
then reduce the heat to
low and watch the coffee
carefully as it boils.
When the foam reaches
the top of the ibrik's
narrow neck and overflow
seems imminent, turn off
the heat and fill each
demitasse halfway with
coffee. Then return to
each and top off with
foam. The end result,
once you get the hang of
it, is a thimbleful of
supremely flavorful
elixir.

TRADE SECRETS FOR
SUPERLATIVE COFFEE
BENCHMARKING COFFEE BY
THE CUP
Walk into any specialty
coffee store that you
know pays knowledgeable
and consistent attention
to its brewing, and
taste the coffee. It's
good, and that is no
accident. The very
costly machinery is
capable of brewing at
the recommended
temperatures and runs an
accurate, 4-minute
brewing cycle. The shop
uses a seemingly large
amount of coffee
relative to the size of
the filter, so paper
tastes are diffused..
With the taste you
experience fixed firmly
on your palate, go home
and experiment with some
of the techniques we
outline in this chapter.
ADJUSTING BREW STRENGTH
If
you want a milder cup of
coffee than the formula
yields, don't get to it
by skimping on coffee.
Chances are, you will
end up with an
underextracted brew,
which may be milder but
will not represent a
balanced, pleasing range
of coffee flavors.
Instead, brew at full
strength and then dilute
the resulting coffee
with fresh, hot water.
This way, you will be
using the formula that
brings you the best
flavor, then moderating
its concentration in the
way you find satisfying.
MATCHING COFFEES WITH
BREWING METHODS
Each of the preferred
brewing methods results
in a dramatically
different finished cup
style, highlighting some
aspects of a given
coffee's character while
pushing others into the
background. Just as
there is a strong and
unequivocal relationship
between the brewing
method you use and the
roast style you enjoy,
so there is a
relationship between
your brewing method and
the kinds of coffee you
like best. Matching
coffee type and degree
of roast to brewing
method may sound rather
esoteric, but it is
really a lot of fun. We
promise: Your guests
will be amazed. Here are
a few generalizations to
get you started.
Manual Drip
The drip method is like
a muted version of
vacuum-pot coffee; the
muting comes mostly from
the paper filter, which
absorbs and retains some
aromatic compounds. This
method yields a cup that
is light in body, and
well suited for early in
the day. A coffee that
tastes a bit too acidic
and light in a plunger
pot will "resolve" as
perfectly brewed drip.
Classic experiences:
Costa Rican Dota or La
Minita, Guatemalan
Antigua, Kenya,
Ethiopian Yergacheffe,
and other coffees that
possess subtle flavors.
Coffee Press
The coffee press
highlights body over
aroma and varietal
nuance. Because of the
slight pressure exerted
on the coffee during
brewing, the perceived
acidity of a given
coffee increases
slightly. This method is
a beautiful match for
medium-roasted Latin
American and East
African coffees and is
perfect above all for
brewing the Indonesians,
whose lush body and
relatively low acidity
seem to exist precisely
for this purpose.
Classic experiences:
Sumatra, Sulawesi, Yemen
Mocha, Ethiopian Harrar,
darker roasts of any of
the great Latin American
or East Africans, and
any good decaffeinated
coffee.
[back to index]
Vacuum Pot
The vacuum pot
highlights aroma,
acidity, and country--oforigin
flavors, while keeping
body relatively light.
It is ideal for light to
medium-roasted Latin
American and East
African coffees. Classic
experiences: Costa Rican
Dota or La Minita,
Guatemalan Antigua,
Kenya, Ethiopian
Yergacheffe, and other
coffees that possess
subtle flavors.

Manual Drip
Brewing
This method is
the original
version of what
electric home
brewers have
long sought to
imitate. Ground
coffee is
measured into a
filter placed
atop an
insulated
container, and
water is poured
over the coffee
so that the brew
"drips" right
into the
thermos..
Amount of
Coffee: For a
1-quart thermos,
use 1 quart of
freshly boiled
water and 2
dry-weight
ounces (.12 on a
digital scale)
of beans. A good
volumetric
approximation
for this amount
is a 12-ounce
paper cup filled
3/4-full, or a
blade grinder's
worth.
Grind: Medium;
about 20-25
seconds in a
blade grinder.
Steps for
Brewing:
-
Put a
kettle's
worth of
good, fresh
water on the
stove to
boil (or, if
the kettle
is electric,
plug it in).
-
If using a
paper
filter,
rinse and
place it in
the filter
holder atop
the thermos.
(Hint: Use a
paper filter
one size
larger than
the holder
calls for.)
-
Grind the
coffee and
place it in
the paper
(or
gold-washed)
filter.
-
Once your
water has
reached the
boiling
point,
remove it
from heat.
Pause for a
moment, then
pour it to
wet the
grounds.
Fill the
filter with
water each
time the
level drops,
continuing
until all of
the water
has been
poured
through the
grounds.
-
Remove the
filter, pour
yourself a
cup of hot
coffee, and
cap the
thermos-but
only until
you find
yourself
ready for
another cup.

Brewing Coffee
in a Coffee
Press
This simple
elegant brewer
is the easiest
way to make good
coffee. Freshly
boiled water is
poured over
coarsely ground
coffee, then
allowed to
infuse for about
four minutes.
The plunger's
stainless steel
filter is then
pressed down
through the
infusion,
resulting in a
very thickly
textured cup
rich in natural
coffee oils..
Amount of
Coffee: Bodum,
the principal
manufacturer of
these and many
other brewers,
defines a "cup"
as 4 ounces. The
1-cup scoop
which comes with
their products
is sized
accordingly,
holding 7 grams
of
medium-roasted
coffee. For the
most popular
1-liter
("8-cup") size,
use 2 dry weight
ounces of beans
(.12 on a
digital scale).
A convenient
volumetric
approximation
for this amount
is a 12-ounce
paper cup filled
3/4-full, or a
blade grinder's
worth.
Grind: Coarse,
about 12 seconds
in a blade
grinder.
Steps for
Brewing:
-
Make sure
the brewer
is clean. If
it has been
sitting
unused for
any length
of time,
residual
oils in the
filter
screen
assembly may
be rancid
and will
spoil
anything you
brew. To
avoid this
common
problem,
disassemble
the screen,
scrub it
thoroughly
by hand with
dish soap,
clean, and
reassemble.
Always store
your plunger
pot with a
couple of
inches of
water
covering the
screens;
coffee oils
only turn
rancid when
they dry.
-
Measure your
ground
coffee into
the press
pot, and
bring a
liter of
fresh water
to boil in a
kettle.
-
Remove your
kettle from
the heat,
wait a
moment to
achieve the
just-off-boil
temperature,
and pour
half the
water over
the grounds.
Give them a
quick stir,
add the rest
of the water
and place
the filter
assembly
loosely on
top. (This
traps the
aroma.)
-
Enter 4
minutes on
your
countdown
timer and
press start,
or keep a
close eye on
your watch.
-
When the 4
minutes are
up, gently
press the
plunger
through the
grounds and
serve. If
you
encounter
much
resistance
when you
start to
plunge, pull
up gently on
the plunger
and then
continue
pressing
down. Always
press
straight
down, not at
an angle, to
avoid
breaking the
glass.

Preparing Iced
Coffee
To brew iced
coffee::
-
Grind and
measure
twice the
amount of
coffee used
for coffee
served hot .
-
Follow steps
2-5 above.
As the
coffee
brews, fill
serving cups
or a pitcher
full to the
top with ice
(made from
good water,
of course).
You may
encounter
extra
resistance
when
plunging.
-
Pour the
double-strength
coffee over
the ice.
Enjoy!
The best coffees
to serve iced
fall into two
camps:
those with
strong floral or
fruity tastes,
such as Kenya,
and those with
milder
characteristics.
Here's an
unusual
must-try: half
Sumatra, half
French.
Mind-bogglingly
strong when hot,
this combination
has great
presence and
persistence when
diluted over
ice.

Brewing Coffee
in a Vacuum Pot
Invented in 1840
by Scottish
engineer Robert
Napier, this
brewer is one
way to reach the
subtler flavors
of truly fine
coffee. It has
two glass or
metal globes
that fit
together to make
a seal. A plug,
often attached
to a spring,
seats in the
upper globe.
Before
assembling, make
sure both globes
are clean and
free from coffee
oils or debris.
Amount of
Coffee: The
Bodum Santos is
the preferred
model-affordably
priced and
high-quality-and
it holds 1
liter. Use 2
dry-weight
ounces of beans
(.12 on a
digital scale).
An easy
approximation
for this amount
is a 12-ounce
paper cup filled
3/4-full, or a
blade grinder's
worth.
Grind: Fine,
20-25 seconds in
a blade grinder.
The grind for a
vacuum pot is
the same as for
drip coffee.
Steps for
Brewing:
-
Fill the
lower
chamber
3/4-full
with fresh
water.
-
Install the
filter,
plug, or
spring
device in
the top
globe.
Measure the
proper
amount of
coffee into
the top
globe and
fit it to
the bottom
globe so a
seal is made
between the
two.
-
Place the
assembled
pot over
medium-high
heat.
-
When the
water heats
to brew
temperature,
it will
ascend into
the upper
chamber.
Stir the hot
water into
the coffee
and lower
the heat.
-
When almost
all of the
water is in
the upper
globe, begin
timing. Any
water
remaining in
the lower
globe will
bubble
slightly,
keeping the
liquid in
the top
globe. At
the end of 3
minutes,
remove the
pot from the
heat or turn
off the
flame.
-
When the
heat source
is removed,
a vacuum
will develop
in the lower
globe as it
cools.
Brewed
coffee will
flow into
the lower
chamber,
leaving
spent
grounds in
the top.
-
When all
coffee has
descended
into the
lower globe,
the coffee
will gurgle
slightly.
Remove the
top globe
and serve.
