Filter baskets

This unit is supplied with 4 filter inserts: 2 standard filter bas-

kets (1 and 2 cups) and 2 double-walled filter baskets.

The standard filter baskets have the same prerequisites as the

filter baskets used in the commercial espresso machines. They

have a single base: you can see many small holes when held

against the light. The standard filter baskets are designed for

fresh, self-ground coffee. To grind the coffee yourself, we rec-

ommend using the GRAEF CM 80 coffee grinder. The grind

setting is perfectly matched to the espresso machines. If you

do not have a coffee grinder, when purchasing the ground

coffee please make sure the coffee grind is very fine, just like

that used in the commercial machines.

The double-walled filter baskets are designed for use with

typical, pre-ground coffee from the supermarket.

Single espresso

The single espresso function is

programmed so that 30 ml es-

presso flow into the cup.

note

We recommend using the filter

for 1 cup.

GRAEFF recommends using water filtered with the BRITA

filter

Even though we have high quality drinking water, filtration

can still be optimised because, depending on the origin of

the water, it contains individual components such as lime,

chlorine or metals such as lead and copper which could

come from the building plumbing. A BRITA water filter re-

duces these substances. That in turn helps develop the natu-

ral aromas and full taste of your hot beverage. On top of

that, it protects your unit from calcification. That extends

the service life and keeps the brewing performance con-

stant, plus the energy consumption remains at the same,

low level.

BRITA – For complete enjoyment of your hot drinks and

longer lifetime of your machine!

Frothing milk.

CAUTION

Never point the milk froth jet at

yourself or at any other person.

DANGER OF BURNS!

Always use the handle to move

the milk froth jet; never touch

the milk froth jet on the pipe

after use. It becomes very hot!

51

Espresso Machine ES 90 / ES 91

EN

Milk frothing with Pan-

narello

 Fill the enclosed container to

1/3 with cold milk.

note

► To achieve optimal results,

use only max. 4°C cold milk.

 Before using the milk frother

nozzle, the condensate that

has collected there should be

drained off. To do that, aim it

at the drain grate and briey

turn on the steam.

 Wait until only steam and no

water escapes and close the

control again.

CAUTION

Never aim the milk frother

nozzle towards yourself or any

other person. DANGER OF

BURNS!

Always use the handle to move

the milk frother nozzle. Never

touch the milk frother noz-

zle on the pipe after using. It

becomes very hot!

 Now immerse the milk frother

nozzle with the Pannarello into

the milk to approx. 1 cm under

the surface.

 Open the steam cock to the

limit.

 Hold the milk container at a

slight angle while doing so.

 Lower the milk can as soon as

the milk level rises.

 PLEASE MAKE SURE that the

milk should not be heated to

more than 70°C during this

process; otherwise, the froth

will collapse and the beverage

will taste too sweet or possibly

even like burned milk!

 A good tip for the correct

temperature is when the you

cannot hold the container for

more than 3 seconds.

note

We recommend limiting the

serving time to ca. 60 sec-

onds.

 Turn open the control knob

again.

 By closing the valve and due

to the steam cooling off a vac-

uum arises in the milk frother

nozzle which then draws some

more milk.

 For that reason, please wait a

moment before you pull the

milk frother nozzle out of the

milk.

 After frothing, briey knock

the milk can on the table top

to remove the last of the large

air bubbles.

 Swirling also helps uniformly

distribute the froth.

 Clean the milk frother nozzle

immediately after nishing the

process using a moist cloth.

However, let the pipe cool

down for a few moments as it

becomes very hot.

52

Espresso Machine ES 90 / ES 91

EN



Also clean the milk frother noz-

zle with a short blast of steam

so that the milk remnants are

blown out of the milk frother

nozzle.

Milk frothing with the

extra nozzle

 Remove the Pannarello and

unscrew the nozzle.

 Screw on the extra nozzle.

 Fill the enclosed container to

1/3 with cold milk.

note

► To achieve optimal results,

use only max. 4°C cold milk.

 Before using the milk frother

nozzle, the condensate that

has collected there should be

drained off. To do that, aim it

at the drain grate and briey

turn on the steam.

CAUTION

Never aim the milk frother

nozzle towards yourself or any

other person. DANGER OF

BURNS!

To move the milk frother noz-

zle, always use the handle;

never touch the milk frother

nozzle on the pipe after using.

It becomes very hot!

 Wait until only steam and no

water escapes and close the

control again.

 Put the milk frother nozzle into

the milk container slightly off-

set.

 That is important so that the

milk is put into a whirling mo-

tion.

 Use the outlet sleeve as a guide

for the milk frother nozzle.

 Open the control knob for the

milk frother nozzle.

Now start the "pulling" and

"rolling" phases

 First the "pull phase": to

slightly stir the air, place the

milk frother nozzle just under

the milk surface.

 You have reached the cor-

rect position when you hear a

"slurping" sound.

 That might stop for a moment

as the surface of the milk is

moving.

 Now the "roll phase".

 As soon as the volume of the

milk increases, push the milk

frother nozzle back into the

milk.

 As soon as the can becomes

hot, close the control knob.

 After frothing, briey knock

the milk can on the table top

to remove the last of the large

air bubbles.

 Swirling also helps uniformly

distribute the froth.

 Clean the milk frother nozzle

immediately after nishing the

53

Espresso Machine ES 90 / ES 91

process using a moist cloth.

However, let the pipe cool

down for a few moments as it

becomes very hot.

 Also clean the milk frother noz-

zle with a short blast of steam

so that the milk remnants are

blown out of the milk frother

nozzle.

note

You can use the method below

to practice frothing milk:

► Put cold water into the milk

can.

► Add a drop of detergent.

► Froth it as described above.

► If you froth correctly, the

mixture looks like real milk

froth.

► Please do not drink this

mixture!!

Making hot water

 Set a container under the hot

water nozzle.

CAUTION

Never aim the hot water nozzle

towards yourself or any other

person. DANGER OF BURNS!

To move the hot water nozzle,

always use the handle; never

touch the hot water nozzle on

the pipe after using. It becomes

very hot!

 Turn the control knob open.

 Hot water now ows from the

nozzle into the container.
