Qu'est-ce qu'un expresso ?

Espresso is one of the most popular coffee drinks in the world. Are you wondering, what is espresso, how to make it and how to drink it? Espresso (pronounced “Eh-spress-o ”) is a concentrated form of strong coffee that is served in small portions. Each shot of espresso is around 30 milliliters or 1 ounce depending on where you live in the world. Espresso is a concentrated form of coffee that is made by using high pressure (usually around 9-10 bars) to force hot water through good quality, finely ground coffee. Espresso has a stronger more intense flavor, with a much thicker texture than normal coffee. This tiny coffee also has a layer of crema on top, which is formed during the brewing process. It's created when air bubbles mix with the coffee's oils, producing the perfect shot of espresso.

Grains d'espresso

When it comes to choosing coffee beans to brew your espresso, you need to know which beans are best for the type of coffee you want to make. It might surprise you that the espresso label you see on the packets of coffee beans doesn't actually refer to the beans themselves, but to the way they have been roasted. Most coffee beans sold, are either Robusta or Arabica beans, which are used in all sorts of coffee drinks. However, espresso beans are roasted longer and are much darker than the beans we would use for regular coffees. So when purchasing a bag of coffee beans, always choose one that is labeled espresso beans or says dark roasted, doing this will ensure you always have a perfect-tasting espresso.

Comment conserver les grains de café ?

Il est indispensable de stocker correctement vos grains de café, car ils peuvent rapidement se détériorer et perdre leur saveur s'ils sont exposés à certains éléments tels que la chaleur, la lumière et l'humidité. Une fois ouvert, le café doit toujours être conservé à température ambiante dans un récipient opaque et hermétique. Il est important de ne pas stocker les grains de café dans un récipient en verre, car la lumière peut en fait faire expirer les grains plus rapidement. Si le café est correctement stocké, les grains peuvent rester relativement frais pendant 8 à 9 mois, mais peuvent se dégrader lentement pendant cette période. Pour un café au meilleur goût, une bonne règle de base est qu'un sac de grains de café ouvert doit être dégusté dans les 2 à 4 semaines suivant le processus de torréfaction et d'emballage. Une excellente façon de stocker vos grains de café est dans une boîte de stockage de café en céramique Airscape. Il a un couvercle intérieur avec une valve à deux voies qui préserve le café pour une fraîcheur optimale.

Expresso Caféine

Considering espresso is served in a tiny cup, it has quite a bit more caffeine ounce for ounce than most other coffee drinks. Each shot of espresso is around 30 milliliters or 1 ounce and an espresso contains about 63 mg of caffeine. Whereas a regular cup of coffee contains between 12 -16 mg of caffeine per 30 milliliters or 1 ounce, that's quite a big difference between the two. The amount of caffeine in an espresso gives it a stronger more intense flavor and thicker texture that we all love. The FDA recommande de ne pas boire plus de 400 milligrammes de caféine par jour, soit environ 6 expressos.

Comment boire un expresso ?

As with most food and drink, there's an etiquette, and drinking espresso is no different. Although espresso is served as a shot, it's not meant to be drunk in one big mouthful. It's supposed to be enjoyed and sipped slowly. Espresso is meant to be appreciated for its unique characteristics of both texture and rich flavor. This can be done in 5 easy steps.

1. Step one, of course, is ordering or making your espresso. If you're ordering remember to pronounce espresso correctly “Eh-spress-o ”.
2. If you're at a posh coffee establishment, you may be given a glass of sparkling water along with your espresso. This is to cleanse your pallet before you begin to drink, so you can pick up the different notes of flavor as you sip your espresso.
3. This next step is optional. Which is to skim the crema from the top of your espresso with a teaspoon. The crema layer on top may look beautiful, but it doesn't actually taste good. In fact, it tastes a little bitter. Crema is a by product of escaping co2 under pressure during the brewing process. Many baristas would recommend this step, but if you like the flavor, you can of course leave it on.
4. Now that you've skimmed your crema, it's time to stir your espresso. This is an important step as the thicker parts of the shot tend to sink to the bottom of the cup while the lighter notes stay on top. Stirring evens out the flavor leaving you with the perfect espresso.
5. Now all that's left is to sip slowly and enjoy the rich dark coffee flavor.
