BUYING GUIDE

How to choose your coffee

It's never easy to find a coffee shop we like at first, and generally when we find one, we don't dare change it.
We also ask ourselves many questions about the terms used, the different roasting methods, and the different labels.

Ma Caféine therefore offers you this guide to help you find your way among the vast selection of coffee available.

In our opinion, this will require the following 4 criteria:

  • Arabica or Robusta?
  • 100% original or blend?
  • Roasting
  • The different labels

Arabica or Robusta?

You might be wondering what the difference is between the two, and especially which one is right for you. 100% Arabica? A blend of both?
Let's first define these two terms.

Arabica is the species of coffee plant called Coffea arabica, which comes from the word "Arab".
It consists of two varieties: typica and bourbon.
It has a very pronounced aromatic profile and contains little caffeine.

Robusta is the variety of the coffee plant species called Coffea canephora.
Its aromatic qualities are weak, and it contains more caffeine. Its main advantage is its low cost and ease of production. This makes it the most widely produced and marketed variety. It is primarily found in instant coffee and vending machines.

Coffea Arabica Coffea Canephora
Altitude 600 à 2400 mètres 0 à 700 mètres
Température 15 à 24 °C 24 à 30 °C
Maturité 6 à 9 mois 10 à 11 mois
Taux de caféine 0.6 à 1.4% 1.8 à 4%

IN SUMMARY

Avec un café à dominante arabica, vous irez chercher tous les arômes du café, et obtiendrez une boisson peu caféinée. Ce sont des cafés qui conviennent généralement aux personnes qui aiment les cafés veloutés, avec des notes fruitées par exemple. Tout leur potentiel est mis en valeur avec des extractions par machine manuelle notamment. Avec un café à dominante robusta, les arômes seront plus subtiles, et vous obtiendrez en revanche une boisson très caféinée. Ce sont des cafés qui conviennent généralement aux personnes qui aiment les cafés corsés, et ils s'adaptent bien aux boissons lattées.

100% Origin or blend?

In stores, you will find two types of coffee: 100% single origin ( pure origin ) and blends of several origins ( blend ).

The term single origin has several definitions, but the most widespread refers to a coffee whose beans come from a single terroir, harvested for example on the same farm.
We can also describe as pure origin the harvests from several farms put in the same washing station.

The blend , meanwhile, refers to a coffee whose beans have different origins, such as country or region.
It helps to harmonize the taste of coffee for the majority, and is widely preferred by manufacturers.
It should be noted that, when well-made, a blend can be just as good as a single-origin wine!

A little anecdote?

Honoré de Balzac, the famous French writer, was a coffee enthusiast and made his own blend by buying his beans from different places in Paris!
If you would like to try it yourself, you will first need to choose the brewing method that will be used with this coffee.
Next you will choose its color, which will determine its tasting profile (aroma, body, etc.)
Ultimately, you'll just have to find the right proportion that will please your palate!
Limit yourself to a maximum of 3 or 4 coffees to avoid diluting the aromas too much and your blend losing its personality.

In summary

Un café 100% origine provient d'une seule place.
Un mélange combine plusieurs origines.

Roasting

Roasting is the principle of cooking the coffee bean for a longer or shorter time in order to develop the aromas it contains.
It is important to know that each green coffee bean has its own potential for aromas and flavors, which it inherits from its variety, its terroir, its method of cultivation or processing.
Roasting allows the full potential to be revealed. The aromas develop during the drying phase and are generally three or four in number.
At the end of roasting, before the 2nd crack (see below) , approximately 800 aromas develop, as well as acidity, flavors, body, and sweetness.

A - Drying phase: during the 1st phase, the coffee bean changes from green to yellow, and its moisture content decreases. The bean then absorbs heat.

B - The internal moisture turns into steam under the heat, and the bean releases carbon dioxide. The pressure then increases to 25 bars, causing the first crack (the characteristic sound emitted by the bean during roasting).

C - Development phase: the grain then gains in volume (1.5 to 2 times more) but loses in mass (up to 11%). It emits heat and turns brown (Strecker reaction) , shedding a skin called "silver film".

The second crack occurs if roasting continues, thus causing the CO2 to continue its expansion.
The grain can then lose up to 22% of its mass.


D & E - Pyrolysis: The aromas are destroyed during this last phase and replaced by bitter flavors, which eliminates acidity and reduces body.

Beyond the second crack, the surface of the grain becomes oily and the texture charcoal-like.

IN SUMMARY

Plus le grain est foncé, plus la torréfaction est prononcée.
Le grain de café perd donc en masse, et mécaniquement le taux de caféine augmente.
Un café noir sera donc plus caféiné qu'un café brun.
De même, il café noir sera plus huileux, la torréfaction faisant ressortir l'huile du café.
Aussi, un café brun aura plus d'arômes qu'un café noir.

THE DIFFERENT LABELS

There are several labels in the world of coffee, which you have surely already seen on a bag and wondered what it could possibly mean.

It should be noted that coffee and tea were among the first products to obtain Fair Trade or Sustainable Development type certifications.

Here is a description of the main labels found on coffee bags to guide you in your choice, while respecting fair, responsible and sustainable consumption, if that is your choice.

IN SUMMARY

Tous ces labels ont des garanties différentes, et sont surtout indépendants les uns des autres. Par exemple, un café bio n’est pas forcément issu du commerce équitable et inversement.

Un label bio garantit principalement l’absence de pesticides et d’intrants chimiques dangereux dans les méthodes de culture, la protection de la biodiversité et le respect des conventions fondamentales de l’Organisation Internationale du travail.

Pour autant, ces labels et certifications sont aussi contestables.
D’une part, il est difficile d’en vérifier les effets, tant les origines de production sont fractionnées et isolées géographiquement. La plupart des fermes sont situées dans des régions montagnardes tellement reculées qu’il est impossible de les auditer régulièrement. Vous ne savez donc pas exactement quels sont les effets de votre achat.
