The art of Espresso coffee
16
Contrary to what you might think, making a perfect Espresso is not that easy. It
takes experience, ability, passion and a little bit of curiosity. In this paragraph
we would like to share with you some of the basic rules for making a perfect
cup of Espresso.
The “5 M”
If you want to make perfect Espressos, you should start by ensuring the
ve essential factors which turn a simple cup of coffee into an Espresso for
connoisseurs! These are the “5 M’s”;
in Italian: miscela (blend), macinatura (grinding), macchina (machine),
manualità (skill) and manutenzione
(maintenance).
1- Miscela (Blend)
Good Espressos are always made with a
good blend of coffee. An Espresso with
the right taste requires a blend of two
types of coffee, Arabica and Robusta.
The rst gives the coffee its delicate
aroma and the right amount of acidity,
while the second type gives it its full
taste, body and cream. The quantities
depend on your own taste. Try out different combinations until you nd the
blend you like best!
2- Macinatura (Grinding)
The grinder is a must for making good
Espresso. Coffee should always be
ground just before it is used so that it
preserves its taste and aroma.
The Lelit grinders let you adjust the
grinding level to suit the coffee blend
in order to establish the correct extraction time and amount of cream.
3- Macchina (Espresso machine)
Choosing the right espresso machine
is equally important. Lelit coffee machines are designed and built to let
you adjust the water pressure and
temperature to your requirements.
The right balance of these two factors
allows you to extract from the ground
coffee not only the substances that
provide its taste, but also the insoluble
particles that give your coffee body
and aroma.
4- Manualità (Skill)
Half of the result depends on how you
use the machine. A passionate expert
is an essential part of the Espresso
production chain and can enhance
the result to bring additional value to
the nal product. Passion and practice
are, therefore, the secrets to learning
how to use the machine. You can experiment with different blends of coffee, grinding, pressing, water temperature and pressure, not just to make
an Espresso, but to make the one that
is just right for you.
5- Manutenzione (Maintenance)
Daily maintenance, scheduled main-

tenance and care of the machine will
ensure the quality of the beverage and
the durability of the product you have
purchased. A clean machine says a lot
about your passion for coffee making.
Coffee varieties
The choice of the blend is an essential
factor for making the ideal coffee for
your taste. There are a lot of different
varieties of coffee blends on the market to choose from. The differences in
avour, aroma and texture depend on
the quantities of the two varieties of
coffee that make the blend.
Arabica
This is a sweeter and more delicate
variety of coffee, with a rich aroma
and cream that is very thin, dense and
compact.
Arabica
It is grown between 900/2000 m
Rich aroma.
Caffeine between 0.9 ~ 1.7%
palate. There are many blends in the
market. Differences in taste, perfume,
consistency depend from the proportions of the two main coffee varieties.
No variety of coffee can make an ideal
Espresso on its own.
The perfect Espresso has a top layer
of cream 2-3 mm thick, a nut brown to
dark brown colour, with reddish tinges
and light streaks, a harmonious avour, a strong, balanced aroma and a
sweet, long-lasting aftertaste.
It has a strong aroma with notes of
owers, fruits, toast and chocolate.
These sensations can last just a moment or can persist for a few minutes
in your mouth. The taste is round and
well structured. The acid and bitter
perceptions are well balanced whereas there is little or no astringency.
The ideal parameters to obtain this
type of coffee are:
7 ± 0,5 g. of ground coee.
25 seconds to brew 30 ml.
88 / 92°C when brewing and 80°C in the cup.
8 /10 bar pressure during extraction.
17
Robusta
This variety is woody, bitter, full-bod ied
and spicy, with little aroma. Its cream is
more frothy and grey.
Robusta
It is grown between 200/600 m
Spicy aroma.
Caffeine between 1.8 ~ 4%
The blend selection is important for
creating the perfect coffee for your
Even Arabica blends often contain a
small amount of Robusta, which is nec essary to enhance the cream and add
aroma and body to the espresso.
Blends made for coffee bars usually
contain 20% Robusta but in southern
Italy, where they prefer a stronger taste,
the percentage can reach 40- 50%.
At the end of the day, it’s just a matter
of taste…Experiment until you nd the
blend you like best!

Cleaning and maintenance
Cleaning and maintenance of the grinder are essential for the quality of the
grinding and the durability of the appliance.
Cleaning
The grinder must be cleaned every 4
kg of ground coffee.
Before starting, remove the plug from
the electrical outlet.
Use a soft cloth, preferably microber,
like the Lelit cloth (code MC972 - not
in cluded), and moisten it with plain
water. Do not use abrasive detergents
and do not immerse the grinder in
water.
out of the grinder .
These deposits, consisting of fats and
oils, due to the high temperatures developed between the mills, go rancid
quickly and create molds that damage
the ground coffee in an irreversible
way.
The cleaning of the mills and of the
mill chamber becomes extremely important. This must be performed with
a specic product (PL104 – not included), i.e a powder formed by small
crystals based on gluten-free food
starches with a very high absorbing
power for oils and fats.
Passing through the mills the crystals clean away the coffee deposits
enabling the grinding of a coffee powder free of odors.
PL104
Cleaning of the mills
It’s well known that the coarseness of
the ground coffee affects the quality
of the espresso in the cup.
During grinding, some coffee particles
deposit between the teeth of the millstones reducing the distance between
the discs, or between the cones and
consequently also the size of the
grains of coffee powder which come
Any eventual residues do not contain
harmful substances to the consumer
or to the grinder.
Cleaning the mills is very easy, just fol-
Page 19
low the following steps:
- Empty completely the beans hopper
(2).
- Press the grinding switch in order to
get rid completely of the remaining
coffee beans.
- Pour a pack of grinder detergent
powder (PL104) into the hopper (2),
paying attention to the fact that the
powder must penetrate the mills.
- Press the switch (4) for about 5 seconds so that the powder penetrates
completely through the mills.
- Fill the hopper (2) with coffee beans.
- Throw away the rst couple of portions of ground coffee.
- The cleaning is over.

Maintenance
We advise to replace the mills periodically, once worn out.
Maintenance has to be fullled just by
an authorized service center and with
original spare parts.
